  • Values are means ± SE. Statistical differences between the 4 types of green fluorescent protein (GFP)-positive neurons with different firing patterns, estimated based on post hoc Bonferroni test, are shown under the corresponding parameter (P < 0.05).

  • n, No. of cells in a group; incidence, occurrence of this type of neuron within the recorded lateral central amygdala (CEl) neuronal population; RMP, resting membrane potential; IR, input resistance; mAHP, medium afterhyperpolarization.
