Long term potentiation (LTP) of responses (local field potentials) of the MGm to brief high frequency (100 Hz, 285 ms) stimulation of its afferents from the brachium of the inferior colliculus (BIC). (A) The average amplitude of the MGm response, with respect to the baseline (n = 7). Note the growth in amplitude over the 1 h post-stimulation recording period. (B) The mean latency to peak of the local field potential. Note the decrease in latency over time. Vertical bars represent ± 1 standard error of the mean. (Gerren and Weinberger, 1983)
