Abstract
Recent investigations into the slow, sometimes rhythmic oscillations seen in extracellularly recorded EEGs have attributed them to oscillations in neuronal membrane potentials (Elul, 1972). Evidence has largely come from simultaneous intracellular recording of membrane potential and grossly recorded EEGs (Fujita and Sato, 1964; Elul, 1964, 1968). Elul (1972) suggests that regular EEG waves, especially of high amplitude, represent synchronous oscillations of potential in many neurons. Although EEG waves of this type may not be a result of summation of action potentials, several workers have related neuronal activity to particular stages of the EEG cycle (Verzeano, 1972; Creutzfeldt et al., 1965; Frost and Gol, 1966; Fox and Norman, 1968). Few of these have considered a possible adaptive function for this relationship, however.
