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.

Researchers control heart rhythm by light

Researchers were able to control the direction of spiralling electrical waves in heart cells using computer-generated light patterns.
