WebMar 7, 2011 · Beginning at puberty, the brain is reshaped. Neurons (gray matter) and synapses (junctions between neurons) proliferate in the cerebral cortex and are then gradually pruned throughout adolescence. Eventually, more than 40% of all synapses are eliminated, largely in the frontal lobes. WebThe dorsal raphe nucleus (DRN) is a heterogeneous brainstem nucleus located in the midbrain and pons. Via widespread projections, which target a multitude of brain areas, its neurons utilize many transmitters to control various physiological functions, including learning, memory and affect.
