A team of researchers has observed what they believe are the building blocks of memories in a mouse brain. In their paper, the researchers describe how they caused certain neurons to become illuminated when they fired, allowing them to watch in real time as memories were made and then later as they were replayed while the mouse was sitting idle.
What are you afraid of? Like it or not your brain knows and now, scientists are starting to understand how it does it.
Scientists at Columbia University in New York have found the neurons responsible for preventing mice from forming fearful memories by looking at a part of the brain called the hippocampus [no, that isn’t where hippos go for an education; yes, that was a awful attempt at a joke].
