By optically controlling the activity of pyramidal cells, we demonstrate that these excitatory neurons induce vasoconstriction when their action potential firing is increased by releasing glutamate ...
The process of deciphering information conveyed by neurons in the human brain is known as neural coding. Conventionally, it has been done by considering how neurons change their rate of firing ...
But in humans, the technical challenges of identifying and analyzing new neurons in adult brains, combined with their rarity, had led scientists to doubt their significance to brain function.
the internal processes that make and remake the brain—the birth of new neurons and death of old ones, the creation and dissipation of neural connections, and more—persist across the lifespan.
