Brain network research focuses on studying the complex network of connections within the human brain. This field examines how different regions of the brain communicate and work together to support various cognitive functions such as perception, memory, decision-making, and emotion. Researchers use techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to map these connections and understand how disruptions in brain networks can lead to neurological and psychiatric disorders. The goal of brain network research is to improve our understanding of brain function and ultimately develop better treatments for various brain-related conditions.
