Kandel’s research showed that although the connections are invariant, their specific strength is not. Homosynaptic changes occur in a synapse because of activity in that synapse, while heterosynaptic ch ...

The outer layer of the cerebral cortex is divided into different areas specialized for detecting and processing sensory signals from the eyes and ears and from receptors for touch, taste, and smell. Differences between these sensory areas may reflect variations in the rate of evolution of the five s ...
