The density of pCCK⁺ interneurons was reduced in CA2 after PILO-SE. The density of pCCK⁺ interneurons was significantly reduced across all subfields of the hippocampus. A, pCCK⁺ interneuron density was reduced in CA1 in SO, SP, and SR. B, pCCK⁺ interneuron density in CA2 was reduced in PILO-SE mice in SO, SP, SL, and SR. C, pCCK⁺ interneuron density was reduced in CA3 in SO, SP, SL, and SR, although the statistical significance of the decrease varied in some layers of CA3b and CA3c, as indicated.
