Retained Primitive Reflexes

With a very broad brush, we can say that the basal ganglia were the primitive motor system, the cerebellum learned precise timing relationships of events, and the hippocampus stored memories of specific events and places.

V1 is concerned with low-level visual features such as tiny edge-segments, smallscale components of motion, binocular disparity (for stereovision), and basic color and contrast information.

Neural learning is reflected in physiological changes in the nerve cells and their connections. Practice leads to the growth of an increasing number of interconnecting fibers that can synapse between cells. The more synapses between adjoining cells, the more likely there will be a direct communication between them, and the stronger the neural netwo

(The same crossover is true for our sense of touch, which is represented farther back in the brain, in a zone of the parietal lobe called the “somatosensory strip.”)
