• © 2015 The Physiological Society. The present study evaluated learning-related synaptic operations across the serial stages of the olfactory cortex-hippocampus network. Theta frequency stimulation produced very different time-varying responses in the Schaffer-commissural projections than in the lateral perforant path, an effect associated with distinctions in transmitter mobilization. Long-term potentiation had a higher threshold in LPP field potential studies but not in voltage clamped neurons;…Read more
