“…The records obtained with a micro-electrode from cats only show that cyclical activity of type-B neurones is occurring at two mean frequencies; there is no indication that the relatively slow oscillatory potential represents a complete discharge of the somata of these neurones. The greater part of the slow potential waves that are recorded may be a contribution from synaptic potentials (Eccles, 1953) similar to that postulated by Li & Jasper (1953) in their discussion of unit activity within the intact cerebral cortex. So far as the phases of potential change described in Fig.…”

“…This activity appears in the records as spikes of about 1 msec duration, and is predominantly either negative, positivenegative or positive in electrical sign. The discharge of these three varieties of spikes can be elicited by afferent volleys, and are believed to be generated from the cell bodies of cortical neurones (Amassian & Thomas, 1952;Li, McLennan & Jasper, 1952;Baumgarten & Jung, 1952;Amassian, 1953;Li & Jasper, 1953;Buser & Albe-Fessard, 1953;Tasaki, Polley & Orrego, 1954). However, it must be borne in mind that the recording of these spike potentials is carried out by blind searching of the microelectrode in the depth of the cortex.…”

“…These data demand careful attention to the biophysical possibilities for neuronal coupling by other than classical synaptic mechanisms. Regardless of the mechanism underlying these relationships between extracellular potentials and unit activity, there is an inescapable implication that the linkage between unit firing and local slow potentials depends critically upon the state of the organism and the specific behavioral operation being performed.It is clear that use of anesthetic agents alters not only the behavioral capacity of the organism, but also the relationship between unit activity and slow potentials (e.g., Li and Jasper, 1953). Even the use of unanesthetized, paralyzed animals is not likely to escape this problem, since uncontrollable shifts in arousal level and attention occur in such preparations.…”
