Brain circuits refer to the intricate network of interconnected neurons in the brain that communicate and work together to process information, control behavior, and regulate various bodily functions. These circuits are responsible for carrying out complex cognitive functions, such as perception, memory, emotions, and motor control. Researchers study brain circuits to better understand how the brain functions, how different regions of the brain are connected, and how disruptions in these circuits can lead to neurological disorders and mental health conditions. This research area often involves using neuroimaging techniques, such as fMRI and EEG, as well as animal models and computational approaches to map and study the activity and connectivity of brain circuits. Understanding brain circuits is crucial for developing new treatments and interventions for neurological and psychiatric disorders.
