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.

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

A new Nature Communications study reveals that mouse hippocampal CA3 circuits start life as dense, randomly connected networks before shedding many synapses to form sparse, organized structures suited ...

The brain’s memory center may begin life more like a crowded web than an empty canvas. Researchers discovered that early ...

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 ...

A new study reveals that neuron networks in the brain's hippocampus, the memory centre, become sparser but more structured and refined as animals mature.

Researchers have developed TD-MCL, a spiking neural network framework inspired by how infant brains grow and prune synapses. The method enables AI to learn new tasks without forgetting old ones while ...
