IHC identification of MNCs recorded in SON slices. (a, b) Double IHC staining for AVP-neurophysin and oxytocin-neurophysin in the MNCs of Lac3 rats injected with biocytin at the end of the recording. The biocytin-labeled cell expresses AVP-neurophysin in (a), whereas OXY-neurophysin in (b). Asterisks indicate recorded cells
