Abstract
The method of one-dimensional current source density (CSD) analysis was applied to field potentials recorded from piriform cortex in the isolated adult guinea-pig brain, mantained in vitro by arterial perfusion. Field potentials were elicited by stimulation of the lateral olfactory tract (LOT), and recorded along 50 μm-step penetrations perpendicular to the lamination of the olfactory cortex. The CSD analysis of the LOT-evoked field potential profiles showed an early monosynaptic sink in the most superficial portion of lamina I (layer Ia), and a second disynaptic sink localized deeper in layer Ib, associated with a source in lamina II.
