The brain contains many cell types, from the prominent neurons to the lesser-known microglia. The latter are integral to the brain's immune system and play a crucial role as the brain's cleanup crew.

Tiny cellular tubes between neurons and brain cells called microglia serve as conduits for the export of toxic protein aggregates from neurons and the import of healthy organelles, keeping ...

Every movement you make and every memory you form depends on precise communication between neurons. When that communication is disrupted, the brain must rapidly rebalance its internal signaling to ...
