Representative traces demonstrating the spontaneous activity of the mHb neurons in a cell-attached mode from TMEM16A cKO mice compared to the one from littermate controls. D. A summary bar graph showing the frequencies of spontaneous firing of the mHb neurons in TMEM16A cKO (4 mice) and littermate controls (The numbers inside each bar indicate the numbers of recorded cells from 4 mice each, paired Student t-test, data are presented as mean values ± s.e.m.).
