Levels of transcripts for 5-HT1A, 5-HT1B, 5-HT2A, 5-HT2C, 5-HT6 and 5-HT7 receptors were significantly reduced (decreases ranged from -48.9 to -75.8%) in AHA group (n=5) when compared to controls (n=8). Transcripts in the PFC were normalized against the geometric mean of Hprt1 and Gapdh mRNA levels. Data are expressed as mean and SEM, *p<0.05.
