Your brain plays tricks to sync sights and sounds

To make sense of complex environments, brain waves constantly adapt, compensating for drastically different sound and vision processing speeds, researchers report. Every high-school physics student learns that sound and light travel at very different speeds. If the brain did not account for this difference, it would be much harder for us to tell where sounds came from, and how they are related to what we see. Instead, the brain allows us to make better sense of our world by playing tricks, so that a visual and a sound created at the same time are perceived as synchronous, even though they reach the brain and are processed by neural circuits at different speeds.

Study shows how our brains sync hearing with vision

E-Mail Every high-school physics student learns that sound and light travel at very different speeds. If the brain did not account for this difference, it would be much harder for us to tell where sounds came from, and how they are related to what we see. Instead, the brain allows us to make better sense of our world by playing tricks, so that a visual and a sound created at the same time are perceived as synchronous, even though they reach the brain and are processed by neural circuits at different speeds. One of the brain s tricks is temporal recalibration: altering our sense of time to synchronize our joint perception of sound and vision. A new study finds that recalibration depends on brain signals constantly adapting to our environment to sample, order and associate competing sensory inputs together.

Sugary brain implant is the softest ever made

Researchers used silicone and sugar to make the softest brain implant ever with a thickness of sewing thread and the consistency of soft pudding.

A sweet solution to hard brain implants

Implants can be used to monitor brain activity or stimulate parts of the brain using electrical pulses. In epilepsy, for example, brain implants can determine where in the brain seizures are happening. Over time, implants trigger a foreign body response, creating inflammation and scar tissue around the implant that reduces their effectiveness. The problem is that traditional implants are much more rigid than brain tissue, which has a softness comparable to pudding. Stress between the implant and the tissue caused by constant movement of the brain with respect to the implant signals the body to treat the implant as a foreign object. This interaction between the implant and the brain is similar
