Brain networks refer to the complex interconnected system of neural pathways in the brain that allow for communication and integration of information between different regions. These networks play a crucial role in various cognitive processes such as attention, memory, decision-making, and emotions. Research in this area aims to understand how different regions of the brain communicate with each other, how these networks develop and change over time, and how disruptions in these networks can lead to neurological and psychiatric disorders. This field often utilizes advanced imaging techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to study the dynamics of brain networks in both healthy individuals and patients with neurological conditions. This research has the potential to improve our understanding of the brain's complexity and could lead to new treatments for brain disorders.
