Resting-state connectivity is a research area in neuroscience that focuses on understanding the intrinsic functional organization of the brain by studying the patterns of spontaneous neural activity that occur when an individual is at rest, rather than engaged in a specific task. This type of connectivity analysis involves examining the synchronous activity of different brain regions and networks to identify patterns of functional connectivity that may be related to underlying brain function and cognitive processes. Resting-state connectivity studies have provided valuable insights into brain dynamics, neural networks, and neurological conditions such as Alzheimer's disease, schizophrenia, and autism.
