To stay in balance, the brain depends on two types of neurons: Excitatory neurons (in white), which increase activity, and inhibitory neurons (in black), which damp down signals. Scientists have now ...

The human brain is a product of evolution. Many psychotherapies and medications focus on adjusting the activity of brain networks that evolved long ago and helped early Homo sapiens survive and ...

The human brain is made up of billions of nerve cells (neurons) that communicate with each other in vast, interconnected networks. For the brain to function reliably, there must be a fine balance ...

University of North Carolina-led researchers have used brain connectivity charts built from functional MRI data as a tool for tracking early childhood brain development. Charts mapped the maturation ...
