A, in one state, cells rest at a moderate RMP and generate tonic firing of APs. B, in another state, MHb neurones display DLAMOs. C, in a third state, MHb cells are mostly highly depolarised and silent. D, in a fourth intermediate state, MHb neurones switch between firing AP-like spikes and DLAMOs. Insets: enlarged AP (a), DLAMO (b) and AP-like spike (d). Note the different vertical scales. The AP-like spikes are significantly different from APs in amplitude (P < 0.001), but not in width (P > 0.05). The oscillations of the DLAMO cells have significantly shorter amplitude and a longer duration than other neuronal states (P < 0.0001). E, the mean RMP is significantly different in the four electrical states of MHb neurones (P < 0.0001). The oscillations of the DLAMO cells have significantly lower amplitudes (F) and longer durations (G) than other neurone states. In E–G, the mean and SEM are plotted.
