Ewepo B. Central pattern generators are neuronal circuits that—when activated—can produce rhythmic motor patterns in the absence of sensory or descending inputs that carry specific timing information.

Rhima Nederland B. Because all brain areas are bidirectionally coupled, these connections between brain areas form feedback loops.

For instance, GABA concentration has been shown to be positively correlated with frequency of oscillations in induced stimuli. Nat Neurosci. Oscillatory activity can also be observed in the form of subthreshold membrane potential oscillations i.
