Summary

Functional near-infrared spectroscopy (fNIRS) revealed occipito-parietal cortex activation patterns in response to checkerboard stimuli. Hemoglobin changes mapped brain tissue activation, with pattern-reversal stimulation showing the most significant response.

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
