The excitability of pyramidal neurons was not changed after sexual attraction. (A) Action potentials were induced by current injection from 50 pA to 200 pA with 25 pA step. The number of spikes was counted at different current injections to measure the excitability of neurons. There was no change in the excitability of IM neurons between two groups. (B) No change in the number action potentials in RS neurons between two groups. (C) No change in the number action potentials in IB neurons between two groups.
