title: Neurons' and glia role in electrocephalogram--evoked potential (EEG-EP) dynamics.
abstract: These studies are concerned with the interactive mechanisms of the EEG-EP in the processing of sensory and cognitive information. The (EP) following auditory and visual stimulation are studied in unanesthesized free moving cats. Special attention is given to frequency and time domain studies of the (EEG) preceding stimulation and the changes in the EEG following auditory and visual stimuli. Special consideration is given to glial and neuronal interactive and their role in the electrogenesis of evoked potentials. Synchronous electrical activity of groups of neurons are likely to depolarize glial cells in distributed brain areas as in (EEG-EP) and sequences of (EP) in periodic flicker light stimulation. These may play a role in coupling processes in neuronal groups. Glial membranes share with neuronal membranes in the extracellular space which neuronal activities can enrich with potassium.
