In the prefrontal cortex, what ages show the greatest rate of decline in synapses (can you give approx. number of synapses per age)?
Same question for the visual cortex?
What accounts for this synaptic rearrangement and why does it occur when it does?© BrainMass Inc. brainmass.com March 4, 2021, 10:54 pm ad1c9bdddf
The human brain at birth contains close to 100 billion neurons. Huttenlocher reported that infants, at birth, have almost the same synaptic densities as adults.
The frontal cortex peak of synaptic density, around 1 to 2 years of age, is 50 percent higher than for an
average adult. At two to 16 years ...
Various phases of the human brain development are discussed.
