Figure 6.
Effects of α-methyl-5-HT (an agonist of 5-HT2A receptors) on the subthreshold BF shifts elicited by the 15 min conditioning (A, C) or the long-term BF shifts elicited by the 30 min conditioning (B, D). α-Methyl-5-HT augmented the subthreshold-BF shifts elicited by the 15 min conditioning (A, open triangles) and the BF shift elicited by the 30 min conditioning (B, open triangles). C, D, The effect of 10 mm α-methyl-5-HT applied before 15 or 30 min conditioning on the frequency-response curves of two single neurons tuned to 23.0 or 33.0 kHz. See Figures 2 and 3 legends for the symbols and abbreviations.
