Value is expressed as mean ± SE; SON, supraoptic nucleus; OT, oxytocin; FR, firing rate; B, burst; Amp (amplitude) of B: spikes/burst; PF, peak FR. ^*P < 0.05 and ^**P < 0.01 compared with the in vivo bursts by Student's t-test, or other parameters with the basal activity in correlation analysis; †P < 0.05 by comparison between basal firing rates of 20 s and 1 min preceding the burst.
