During this period, higher cognitive functions such as planning, problem-solving, and decision-making gradually mature. Yet, the underlying mechanisms of neural circuit development remain poorly understood.<\/p>\n<p>Key to this process are synapses\u2014the functional connections between neurons allow information to flow through the brain. Previously, it has long been hypothesized that synapse numbers increase during childhood and then decrease during adolescence. It has also been proposed that excessive \u201csynaptic pruning,\u201d a process that refines neural circuits by eliminating unused or weak connections, may lead to neuropsychiatric disorders. One example is schizophrenia, a condition characterized by hallucinations, delusions, or disorganized thinking.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers from Kyushu University discovered a previously unrecognized synaptic \u201chotspot\u201d that forms during adolescence, challenging the long-held view that adolescent brain development was dominated by synaptic pruning.
