(A) Representative traces of loose patch recording from a Purkinje neuron at 7 dpf showing tonic (top trace) and bursting (bottom trace) activity patterns. Small amplitude events (red arrowheads) interspersed with large amplitude events (blue arrowheads) can be seen. (B) Superimposed events of large amplitude (blue) and small amplitude (red) events from one cell showing the mean in the respective colour (N = 6 cells). (C–E) Intracellularly, Purkinje neurons show three types of events. Current clamp recordings of spontaneous activity at −65 mV (C) and −45 mV (D) showing large amplitude events (blue arrowheads, C, D), small amplitude narrow spikes (red arrowheads, C, D) and broad spikes (green arrowheads, D). (E) Superimposed events from one cell with mean shown in the respective colour for each type of event.
