Table 1: Qualitative expression of Ar mRNA distribution by nuclei in postnatal and adult mouse brain.
−, +/−, +, ++, +++, and ++++ represent not detected, very low, low, moderate, high, and very high expression of silver grain deposits corresponding to Ar mRNA. The Allen Mouse Brain Atlas was used as a reference for names, abbreviations, and location of nuclei.
