Our memories reside in specific brain cells: MIT researchers

Our memories reside in specific brain cells: MIT researchers

The researchers used optogenetics to show that memories really do reside in very specific brain cells, and that simply activating a tiny fraction of brain cells can recall an entire memory.

How brain retrieves specific memories

How brain retrieves specific memories

A team of US researchers has used light to erase specific memories in mice, giving an impetus to the basic theory of how different parts of the brain work together to retrieve episodic memories.
