Abstract

The electrical tetanization of the lateral olfactory tract at a frequency of 30/sec for 15 sec elicited the development of posttetanic potentiation of populational EPSP and IPSP in surviving slices of rat olfactory cortex. The stimulation of the lateral olfactory tract by series of stimuli at a constant frequency of 10/sec and with intervals of 4–5 sec between series facilitates the emergence of the phenomenon of frequency potentiation. The data obtained indicate that such forms of functional plasticity as posttetanic and frequency potentiation are manifested in the pyriform cortex.
