My brain cells are dying in their trillions.

I like nonsense; it wakes up the brain cells.

Ideas not coupled with action never become bigger than the brain cells they occupied.

A meticulous virtual copy of the human brain would enable basic research on brain cells and circuits or computer-based drug trials.

This is a well-studied part of the brain. These are large cells that weren't really hiding.

Throughout our lifetimes, we are constantly regenerating new brain cells in the hippocampus, a process called neurogenesis. New stem cells are constantly being born in the hippocampus that ultimately differentiate into fully functional neurons.
