[Effect of various concentrations of corticoliberin on long-term potentiation in slides of the rat olfactory cortex].

Perfusion of the rat olfactory cortex slices with 1 mcM corticotropin-releasing factor (CRF) increased the rate of initiation of the posttetanic potentiation. The latter had a shorter supporting phase than in the control. With the perfusion, with 0.1 mcM the potentiation had a longer supporting phase than in the control.
