GABA signaling prunes back copious 'provisional' synapses during neural circuit assembly
Quite early in its development, the mammalian brain has all the raw materials on hand to forge complex neural networks. But forming the connections that make these intricate networks so exquisitely functional is a process ...

How does the brain know what the tongue knows?
Each taste, from sweet to salty, is sensed by a unique set of neurons in the brains of mice, new research reveals. The findings demonstrate that neurons that respond to specific tastes are arranged discretely in what the ...
