Abstract
Negative shifts of the cortical DC potential can be conceived as valid indicators of cortical activity. DC shifts are associated with excitatory post-synaptic potentials which arise in dendritic trees of neurons located in superficial layers of the cortex (Caspers et al., 1980). Although being of neural origin, DC shifts may be mediated to some degree by glial cells which serve as a local buffer for potassium (Bauer, this volume; Laming, this volume) or, in scalp recordings, by regulatory mechanisms of the blood-brain barrier. Surface-recorded DC shifts seem to be more directly linked to neural activity than are, for example, measurements of blood flow and metabolism obtained by PET (Positron Emission Tomography) or SPECT (Single Photon Emission Computerised Tomography). Joint studies of DC shifts and regional cerebral blood flow, as carried out by our group, revealed converging results between those methods but that of DC shifts showed a higher sensitivity to event-related patterns of cortical activity (Lang et al., 1988a; Goldenberg et al., 1989; Uhl et al., 1990a). This has motivated us to use DC shifts for functional localisation.
