Mice Can Mirror Pain, Fear and Emotions of Each Other through Social Contact, Says Study
FOLLOW US ON:
Be it feelings of pain or pain relief, new research has shown that mice can mirror those emotions in their brain and, as a result, feel the same way as their companions.
For example, if an injured mouse come across a healthy companion, the social contact is enough to pass on the pain to the fellow mouse. Soon, the bystander mouse will start behaving as though it is in pain. And this transfer of emotions isn’t just restricted to pain it’s the same for fear and pain relief as well.
In pain and pain relief, mice may feel for each other.
Research has shown that mice can “catch” the emotions of an injured or fearful fellow. When some mice are injured, other healthy mice living alongside them behave as though in pain. Now, a study suggests that not only can pain be passed along, but also pain relief is contagious too.
In the last decade, researchers have done a lot of work showing that animals can pick up and share each other’s emotions, particularly fear (

New tool for watching and controlling neural activity
A new molecular probe from Stanford University could help reveal how our brains think and remember. This tool, called Fast Light and Calcium-Regulated Expression or FLiCRE (pronounced “flicker”), can be sent inside any cell to perform a variety of research tasks, including tagging, recording and controlling cellular functions.
“This work gets at a central goal of neuroscience: How do you find the system of neurons that underlie a thought or cognitive process? Neuroscientists have been wanting this type of tool for a long time,” said Alice Ting, professor of genetics in the Stanford School of Medicine and of biology in the School of Humanities and sciences, whose team co-led this work with the lab of Stanford psychiatrist and bioengineer, Karl Deisseroth.
