Home > Conscious > 4. Neural Oscillations

 

Neural oscillations are rhythmic or repetitive neural activity in the central nervous system. In single neurons, it may display as periodic changes in the membrane potential below threshold, or a train of nerve impulses (Figure 4-1). A population of neurons may also oscillate synchronously. The brain waves recorded by electroencephalography (EEG) are the results of synchronized oscillations. They play crucial roles in conscious perception and memory functions.
