Adolescence is widely thought to be a time when the brain trims away excess neural connections, refining circuits through synaptic pruning. New research now suggests this view may be incomplete.

Researchers from Kyushu University discovered a previously unrecognized synaptic "hotspot" that forms during adolescence, challenging the long-held view that adolescent brain development was dominated ...

The hippocampus follows a "tabula plena" model, starting with dense, random connections that are pruned into an efficient ...

As animals experience new things, the connections between neurons, called synapses, strengthen or weaken in response to events and the activity they cause in the brain. Neuroscientists believe that ...

Researchers have mapped and catalogued more than 70,000 synaptic connections from about 2,000 rat neurons, using a silicon chip capable of recording small yet telltale synaptic signals from a large ...
