Neural activation refers to the process by which neurons in the brain become active and communicate with each other, leading to various cognitive processes such as perception, memory, and decision-making. This research area aims to understand how neural activation patterns are associated with different cognitive functions and behaviors, using techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to measure brain activity. Researchers in this field seek to uncover the neural mechanisms underlying various mental processes and disorders, with the ultimate goal of improving our understanding of the brain and developing new treatments for neurological and psychiatric conditions.
