What does you know about the link between smell and memory . Find out why we so send a mental and other secrets of the brain. Now on tomorrow today. There is symbol and love. A nice smell wonderful. On that frequency can also help you learn new vocabulary. According to a gym and research team, the scent of roses helps the brain retain information advice just as we know thats and plays a very special role in learning. So we, by, you know, as many dates will come when we learn vocabulary or anything, we learn it in a specific context. One is keep flipping smells, something that you often smelled in your childhood. Youre immediately transported back to it and the contents of what fits into a level to investigate exactly how sense influence on the brain. Human biologist, you can call my on his team, conducted an experiment, is a 165 test subjects were given envelopes and how to study japanese vocabulary for 3 days. Cost study participants had a sent it over the field with dried rose petals. The control group and sent it on the loops filled with clean scraps of paper. Those who was surrounded by just send a rose as did best to in the vocabulary test. Remember, and on average 8 and a half percent move a category. The team observed that the sense proved especially effective when the autism and spot and the time pressure that decides when theres not much time or theres just a lot to learn. Theres sent appears to act like a kind of brain booster helping it retain as much as possible this month to move on to some of the study participants were exposed to the rose cent, not only while they studied, but also while they slipped. The research has wanted to know if this would help the brains still move to new information. Funding the so id be interested in question is, what are the criteria for our brains to decide what goes into the long term memory and what doesnt . And beyond that, can external factors influence this Decision Making process here for an hour and, and thats where sense comes into play when i come to, to fix. Thats because sense can influence the brain while were sleep or learning specifically to keep a compass which mediate between short and long term memory. Receiving smiles is directly connected to the compass. Information of sold the same time, 10 inches long term memory more deeply. At least not the theories, sleep also plays a crucial role experiments in a sleep. The board tree have shown that during the deep sleep phase, the brain reorganizes that these parts of what it is learned on decides which information is moved into the long term memory. Sense effectively reactivate, so what was the doing the day when these of them, when what was learned is reactivated into the brain, the probability increases that people be consolidated and it can only be what exactly happens in the brain during this process remains a mystery. But brain scans show that smells, can activate the compass even in deep sleep. If the brain has already associated information with a sense during the day, the sent alone can help it to store it at night. One possible explanation to say nerve cells activated. So what were ready finding when the person was awake, in order for the sense to help with learning, it has to be used in an actual test. For example, a vocabulary test. This helps the brain access to what it is learned, at least for a few days. But the scent of roses doesnt protect against guessing. The effect doesnt appear to be known to. However, it definitely can help would show 10 vocabulary learning. But why roses . Its actually quite random. It was the frequency used in the 1st study on the topic. Latest studies also use rogues sense, so that the results could be easily compact. This event is why we and many other colleagues use rows, fragrance because of the original study uses rose fragrance of a. But im firmly convinced that other frequences also work. But that has to be shown of course in further studies. So its possible that lavender posted trust, for example, can also help consolidate learning. At least initial tend, researches are still figuring out how the brain Stores Information in memory and processes it at night button. And then the next time someone gives you roses, they can also help you vocabulary learning skills. Or our brains also help us feel emotions. Debina bowes, it is a view from bosnia and herzegovina with a truly timeless question on this subject. What is love . Its a sensation that puts up bodies interest agents. Imagine, see, similar to when danger lose the offerings go into overdrive sending out like hotel if different, new, or transmit is that stimulates all senses and ignite a firework, of intense feelings. In the 1st phase of falling in love, applaud is flooded with a gentleman. Thats the same hormone thats triggered by exploration of stress and gives you bucks or flies in your stomach. It causes ops you polls to die late. The body is push on that causing Blood Pressure impulse to rise. Meanwhile, oxy towson helps with funding and developing trust oxy. Towson is often the cut all hormone as its produced through physical contact. The come in and serotonin. Notice the happy hormones are of course, also positive being in love, but in the early phase also are turning levels of from fluctuate. For example, when intoxicating happiness tends to desperate loaning, when was separated from the one we love, the studies of brain waves show that being in love especially activates the areas of the brain that are responsible for sexual edges. So can we conclude that this homeland cocktail was only created by nature to ensure that we focus on one pond during reproduction in time of bodies getting used to the high level of the says of home in the end after 2 to 3 years at the latest the immediate thrill of infatuation is the fact we do commit to long term partnerships and are keen to help each other out. Thats because we have social creatures who do arrive satisfaction from supposing each other. Researchers have identified specific parts of the brain that enable us to feel empathy. I found 20 years yesterday bridge monday, the 1st one ive been strictly schematic because my research has shown that we are all fundamentally empathetic people very much. So in new jersey to soon when ever the situation, we simply feel what other people feel attached to the ones i basically to have in our western world. We tend to see each other very much as individuals. But what my research has shown is how strongly were shaped by the people around us. And even though its a one say home, just young kinds of isnt numerous scientist. A lot of his research has focused on how well brains empathize with other people. His research was quite a presumptive experiment, 1st thought into for us to undergo an m r i scan. So it has things you want to understand how our brains enable us to empathize with other peoples feelings. Countries. We needed to be able to trigger certain emotions during the scan and for this high speed review, most of them. So we had to find a stimulus that could be vocal powerful emotions. And con, when i remember, please got to be a good form. And one way we found him doing that was the place and a seizure mask on the test person, and then introduce various smells through the mask during the scan. And im thinking most trigo Chain Reaction in our range that when mostly unaware of within many seconds, we register whether the smell is pleasant or notes. And we respond accordingly. Also with a physical reaction. If the smell is repulsive, we automatically put a face and once leave stomach attract new stream cases, we might even throw out it was these kind of repulsive smells. Christian kinases tested. Im the one smell that works really well is blue teoric acid is it really smells like butter thats gone. Really rancid. Couple of nice in the next run, the test participants, just the videos of people looking disgusted without smelling anything for themselves. The facility, whats shown here is what happens when the test participants smells something unpleasant themselves get kicked up the so called in say there is exit, which we know is involved in processing smiles. Where it gets interesting is when we look and see what happens when the touch of the candidates, just see other people responding to bad smells even days. The twos guns on top of each other. The i b as in white show where they call relate, then come on even q. You can see how a part of their own experience have discussed was reactivated activity. It said, then they in see they really feel their stomach contracting. For example, somebody speak the magnitude or they sense the unpleasant tastes or smells and it gets smack out. Would that cause they sure, and the insane the knowing how bad we feel when were in pain, we have an automatic edge to help the brain rewards us for them. When we do something good, it releases the whole names. They lower our stress levels and strengthen means systems that even effects on the dna dining down so called risk genes, which would otherwise promote information or chronic conditions like cardiovascular disease, cancer, or dimensions. So choices of remaining healthy increase but some people dont seem to have any sense of entities to others at all. Christian and kaiser studies this going to to understand what happens and what goes wrong. In these cases, we worked with a number of psycho pads from high security jails and also because of the investigative dodd. And what we observed is that when the psychopaths watched others suffering pain, the area of the brain involved and feeling pain was hardly activated at all. On the tune for the ice deep so. So at 1st we thought ok, maybe psychopaths do the terrible things they do because they just cant feel pain in thinking kind of but psych of us are often very good me placing people to do that. They actually have to be able to empathize quite well. So the research has told them to actively imagine themselves in the place of the victim he was currently experiencing pain. Suddenly the brains responded, just like those of the sophie test participants, that they can be a good man to single one of us that made us realize that the problem is not that psycho pads. So were unable to emphasize. Its just that they dont empathize spontaneously on. They only do it when they want to know done it to finish the material volume. Another surprising finding, we can old regulate on level of empathy according to the response to meet it. Hello, did you burn yourself depending on the situation . Im the on your lets go on cool. Let christy on kaiser is now studying whether its possible to help people with mental disorders become more empathetic. Tea already succeeded in doing the opposite in another study setting that entity can be suppressed. If i do find the experiment was actually quite simple and we showed each candidate a person being slapped on the hand on them. And then we gave them 6 zeros each and said they could choose what to do with it. They could keep the 6 euros, but then this poor person would have to be slapped again just as hard and with what does or they could give some of it away. Right . Every year they gave away the slap would be 110th less painful, because for that test, on the 1st go, they found the heart of the slump, the more money the candidates gave away. Once, once its gone, then we measured how that behavior changed. Because when i use the magnetic stimulus to disrupt the activity in the so matters sense, record checks and teeth ends and lots of things organize can call, takes a touch through it. Thats the part of the brain that receives pain, even when just watching it being inflicted on audits. The temporary disruption to this function meant the candidates response no longer depended on the strength of the something. They couldnt differentiate the pain anymore. So several parts of the brain, the networks have to Work Together in order for us to be suitably empathetic, being empathetic, his own natural state. When we use that to help others, if youre feeling better, ask you to them, getting them empathy to actually make us happy and content which could help us to keep healthy. Myself. In may 2023. This story gone at global interest, a paralyzed man walking again. Thanks to electronic brain implants, these devices, we quote his brain signals and send the data to a possible computer. That data has been transmitted to another implant in his spinal cord, which poses only instructions. The simple daily task of going to the market to get for st with something that get to you on really messed the 40 year old with less paralyzed officer an accident 12 years ago. Now he can once again enjoy this simple pleasure. The dutchman is the 1st person to receive a new type of double implant that creates a direct new, or electrical link between the brain and the spinal cord. Via a wireless digital interface. Doubt to young can control his paralyzed legs with his intentions. Its cool, it was the 1st time i bought something in the market while walking. So the right spirit, john comfortable, perfectly. So he can do things that were until recently, impossible for him. With a walking age he can stand, woke, and to even climb stairs through training. His movements are improving from day to day. Listen, you are a scientist. So being researching the technology for many years now in a fast version, that was just an implant in the spinal cord. The come ons to walk came via a tablet. Now this and 5 the brain to a processing unit, and the movements a mo, natural socratic with the preprogrammed stimulation walking was much more robotic, not very fluid. Now though, because the brain directly controls the stimulation, we have a very smooth coordinated gate escape and well send updates in this with paraplegic center, the research is being followed with great interest. Its not yet secure, but its the best possible technical solution says the head physician. These, if you those of fi, these is concepts, the concept with them. This development is fantastic to close time to come to i believe its the future, at least until we have a therapy with which we can heal spinal cord injuries, island can assist you. Its definitely new and exciting and will trigger a great amount of emotions amongst our patients, how houses and bios im putting in this new concept. Harolds a new era in the treatment of maybe 2 deficits in the future. Some of the technology will likely be able to restore the function of the ohms and hands as well. Brain implants can also use the symptoms of parkinsons. The treatment can reduce, trim is and muscle rigidity using electrical stimulation. Many patients who suffer from the disease have benefits. Jim is idle is conscious during the operation to implant electrodes into his brain. The surgeon needs him to respond and speak desirable was diagnosed with parkinsons in his mid forties. Despite heavy medication, his tremors wont go away. Hes hoping deep brain stimulation will help the citizens. We can see the tremors very clearly. Now were going to stimulate individual contacts the day before the procedure. The went down for a walk. Hes not scared. He just longs for the tremors to stop. You can see how much im trembling with the im not shivering due to the cold. Its the tremor hunter, my handwriting is affected. I also leisure activities going out to eat with my wife. Some people just see me for the 1st time. Think i can count up to 3, they talk down to me. So 1st of this guidance parkinsons forced him to cut down his working hours. He cant go on business trips, let alone run them, our phone, and the drugs that are intended to boost doping mean levels in his brain effect his mood. I want my life that due to being ins, university hospital, they have long experience with deep brain stimulation. This brain piece baker can be adjusted as the illness gets more severe or symptoms change to be able to respond quickly. They have recently begun to use a smart watch to measure tremors, agility and sleeping patterns by his sensors. On the inside of the high can see your hand is moving about and also your arm a little bit. The legal does on those movements are now being recorded and stored. Its like a long term monitoring fee and hes on long testimony. Totally. Numerous parkinsons sufferers have already under gotten this procedure world wide. It almost doesnt draw any blood. Tiny holes have to be drilled into this go for the electrode implants from there on its a highly delicate operation. Planned with c t images during the operation measurements are taken to gauge whether the electrodes are in the right place. Were going to check the shows in the region step by step 10, up to flip the switch. They have to be implanted several centimeters deep into the brain. Tims idle has to continue to raise his arm. The system that gets all the tremor is also being measured via the motion sensors on your arm and the watch which we fitted yesterday with the well. If it gets done on the block column, after 4 hours the electrodes are finally in place, no jim sidle can finally sleep. Under general anesthetic, they connect together the cables under his skin and implants, the brain pace, maker below his collarbone. A deep brain stimulation is becoming increasingly sophisticated. Growing knowledge about individual areas of the brain means more precision. As part of an international study, they are now testing how closely they can monitor a patients condition by collecting data via smartwatch. Definitely technology now gives us access to a constant stream of information from what we know about daytime fluctuations. We know whether things are better or worse mornings or afternoons. We know whether a patient would benefit from an adjustment in the mid to long term from an annoying items to them for the treatment is working for teams. Idol. He is back in the hospital 8 weeks later, for minor tweaks. Neurologist daniel, vice switches off the brain piece. Baker 1st to see how bad the symptoms are without any correction. Yes, your right hand is an out trembling a lot more if its too uncontrollably. Uncontrollably told you are like that again. My leg is a starting now. One thing ill switch the stimulate around again, and the tremor disappears with the flick of a switch. Thats it takes just a 2nd source when you switch it on or off, the effect is immediate. On like tablets that can take a long time. My upside, im really pleased. Its worked for me, but thats something that jim sidle can write neatly again. I can easily eat and work in the garden with his wife the others because i dont have to take care of my parkinsons anymore. And i can look after myself and plan and didnt join my leisure time. Can you give me the tools again . I can also use a chain, sorry to cut down a branch, but i prefer to do it by hand as well. I enjoy the fact that i can team is wife or even planning a trip on a tim, the elbow to but the procedure doesnt work as well for everyone. Deep brain stimulation can also cause side effects just like medication symptoms can persist or return. But the 2 of them just want to look ahead lets go back on quality of life. We still have plans ahead of us and hes so young and so you would have been a shame if he hadnt done a shot events. Enough missed you must. It is another huge benefit. He doesnt have to go to the hospital as much anymore is brain pace maker can be adjusted remotely. How have you been likely . Uh, ive had to take much less medication. The tremor is really diminished as soon as the negative on the doctors can access his implanted pacemaker from the hospital. Of course, Data Security has to be very tied a customer, thats what we get slightly increase the stimulation level today. And those comes i can do this right now. Fire Remote Control. Yes. Lets try and my stuff. Its mostly that. Okay. Then ill do it. You wont notice much, but ive switched it from 2 to 2 point one. Do you feel . All right . Yeah, yes. I think its working on electrical impulses relayed via Remote Control just a few years ago. That would have been science fiction. Today. Its reality. This technology is improved and teams, idols, quality of life, along with it. Let us read. Why do you have a science question . Send it to us as a video, text or voice message.
