Figure 3.
Comparison of effects of 5-HT1A and 5-HT1B agonists on spontaneous and evoked activity. A. Histogram of spontaneous spike rates in neurons tested with the agonists. Most neurons had low rates of spontaneous activity. B. Proportional changes in evoked versus spontaneous spike rates induced by 8-OH-DPAT and CP93129 for neurons with spike rates over 1.5 spikes/sec. Changes in spontaneous and evoked activity are represented as transformed values (log[drug/control+.1]), so that all values are nonzero.
