Information comes into the hippocampal system from the cerebral cortex, including the visual, auditory, sensory cortices and the motor cortex.
The evidence for synaptic plasticity in adult primary visual cortex is growing rapidly and is paralleled by work in other adult sensory cortices as well.
Using transcranial magnetic stimulation, we found that productive and receptive linguistic tasks excite the motor cortices for both hands.
By contrast, learning a complex motor skill induces plasticity in motor areas of the brain such as the motor and cerebellar cortices.
The patients showed reduced activation in both visual cortices, with increased activation in a number of left-sided structures.
Again, whole cortices were isolated with no attempt made to correlate the images with either the animal or vegetal hemispheres.
Because the visual cortices of synapsids and sauropsids derive from different portions of the dorsal pallium, they cannot be homologous as visual cortices.
Rather, sensory cortices may receive input normally but fail to send and receive inputs from higher order association regions, due to deficient long distance connectivity.
