“…in the developing conditioned reaction. In addition to lowering the threshold of the involved cells (Burns, 1954(Burns, , 1955, the anodal current appears to confer upon these cell populations the property of retaining, at least for a short period of time, a representation of a stimulus imposed during the polarization. Indeed this may be demonstrated even more graphically if one shifts the polarizing electrode to the visual cortex and studies the effect of single or rhythmic stroboscopic stimulation.…”

“…This suggests that the functional unbalance exists in the organisation of the general regions of the brain and it is not always necessary to postulate a punctate localization of epileptogenic tissue in a definite area. The neurophysiological foundation for the disturbances of the organisation in the general regions of the brain will remain unknown until more precise illustrations of the mechanisms of neuronal nets (Burns, 1955) in which neurons are completely connected with each other and with other cells by their dendrites are made available.…”

“…A 200 msec 60 Hz current of 200 mA was applied by means of corneal saline-wick electrodes, This current intensity regularly produced maximal electroshock seizure patterns. These potential differences may arise by differential repolarization properties of contiguous portions of neurons (3,14) or as a result of mechanical deformation of part of a cortical neuron (20,29,30). 10 shows a dose-response curve relating the incidence of maximal seizure with dose.…”

“…Thus, Schmidt et al (20), Ward (29,30), Burns (3) and Pinsky and Burns (14) have suggested that the probable underlying mechanism in the generation of cortical high frequency nerve activity is a generator potential created by intra-neuronal potential differences. These potential differences may arise by differential repolarization properties of contiguous portions of neurons (3,14) or as a result of mechanical deformation of part of a cortical neuron (20,29,30). In any case the nerve axon, which is capable of rapid recovery, is exposed to some long-lasting cathodal influence and therefore fires repetitively.…”
