Nicotine-induced neuronal activation in polysialic acid-positive neurons in the hypothalamus. A Representative immunohistochemical images of the hypothalamus from WT and neu1-KO zebrafish. Fluorescence intensities are expressed relative to the WT value. n = 3. B Double immunofluorescence staining for c-Fos (red) and PSA (green) in WT zebrafish following Nco exposure, with merged images showing spatial association between neuronal activation and PSA-positive regions. Nuclei were counterstained with DAPI. PTN, posterior tuberal nucleus. HC, hypothalamic periventricular complex. Scale bars, 100 µm
