For over 100 years, scientists have agreed that discrete collections of brain cells fire off signals to other brain areas through a series of interconnected fibers. In a new study, researchers applied ...

From a tiny sample of tissue no larger than a grain of sand, scientists have come within reach of a goal once thought unattainable: building a complete functional wiring diagram of a portion of the ...

It provides a draft of the connections in the cerebral cortex – the outer layer of the brain responsible for activities such as reasoning and planning – and fills in some of the important blanks ...

The brain of a common fruit fly (Drosophila melanogaster) is no larger than a poppy seed, but the miniscule piece of tissue holds tens of thousands of neurons joined by tens of millions of synapses.

Comparing a map of the neurons in a nematode worm - the connectome - with a map of how signals travel across those neurons ...

Adolescents who regularly choose solitude over social connection show measurable differences in brain structure and function, according to a large neuroimaging study.
