Figure 3.

Comparison of axons containing the serotonin reuptake transporter (SERT) in C57 (A) and BTBR (B) mice. Images are of comparable fields in the CA1 subfield of the hippocampus including strata pyramidale (P) radiatum (R) and lacunosum-moleculare (L-M). (C) SERT axon density in BTBR mice is about 16% less than in pair-matched controls, (P = 0.0007) N = 8 per group. Bar = 150 μm.
