Firing pattern of Purkinje cells in single cell extracellular recordings (A and B) or MEA recordings (C and D).

<p>The main firing pattern observed were a tonic pattern (<b>A</b> and <b>C</b>, in blue) or a trimodal-like pattern consisting of a period of higher activity followed by a phase of tonic activity and a period of silence (<b>B</b> and <b>D</b>). Purkinje cell activity was comparable with both recording methods. For each example, a short portion of spike recordings (top trace), the firing rate (middle trace) and the auto-correlogram of the single neuron (bottom trace) are represented. The peaks in the correlograms show that cells are spiking with a regular period. Insets in (<b>C</b>) and (<b>D</b>) depict the waveform of averaged single units.
