Document Summary
Resting state: when the brain is not subject to any stimuli. Resting state network: a group of neurophysiological regions that show resting state functional connectivity. Function connectivity: referring to regions of the brain that share functional behaviour. In other words, spatially remote neurophysiological events (neurons ring, synapses communicating) that seem to be temporally correlated (occur at the same time at a frequency greater than chance). Functional connectivity is expressed with and without a stimulus. Structural connectivity: regions of the brain that are anatomically attached. Structural connectivity functional connectivity and vice versa. There may be a link in certain cases, but this is by no means established. Resting state functional connectivity: neurophysiologically related areas during a state of rest as determined by bold testing (usually). Can be illustrated in averages or over time (see dynamic functional connectivity). Dynamic functional connectivity: observable changes in functional connectivity that occur over time (time scale of seconds).
