Developmental plasticity: Pruning
... The GM density on MRI is an indirect measure of a complex architecture of glia, vasculature, and neurons with dendritic and synaptic processes. Studies of GM maturation show a loss in cortical GM density over time, which temporally correlates with postmortem findings of increased synaptic pruning du ...

... The Cerebrum is the largest area of our brain. It makes up almost two-thirds of the volume of the total brain. The outward appearance of the cerebrum has a wrinkled surface. This “wrinkling” allows for a greater surface area so that more nerve cells (neurons) can fit into a smaller space. (Think abo ...
