histamine receptor h3 (hrh3) plays roles in anxiety and cognition, and recent findings suggest that this receptor could be a potential therapeutic target for ASD (Baronio et al., 2015; Eissa et al., 2018), but mao+/+ and mao+/− brains presented similar levels of this transcript (n=4 for each genotype; P>0.05; Fig. 8C). This evidence concerns the gene HRH3 and Anxiety.
