Long-term potentiation induced by physiologically relevant stimulus patterns

Single pulse stimuli were delivered to the Schaffer collaterals in the in vitro hippocampal slice preparation.

Zusammenfassung:Single pulse stimuli were delivered to the Schaffer collaterals in the in vitro hippocampal slice preparation. Local application of bicuculline to the Ca 3 region resulted in a series of population cell bursts in CA 3, resembling the neuronal patterns which occur in the normal, freely moving rat during hippocampal sharp waves. These bicuculline-induced cell bursts in CA 3 resulted in long-term potentiation (LTP) of the CA 1 response. These findings suggest that the naturally occurring hippocampal sharp waves may reflect events analogous to artificially induced LTP.
