Neural circuitry is the field of neuroscience that investigates the complex network of interconnected neurons in the brain and nervous system. This network of neurons forms the basis for all cognitive and behavioral functions, including perception, memory, decision-making, and motor control. Researchers in this field study how individual neurons communicate with each other to form circuits, and how these circuits are organized and function to process information. Understanding neural circuitry is crucial for elucidating the mechanisms underlying various neurological and psychiatric disorders, as well as for developing new treatments and interventions.
