Figure 1. Clustering of experimentally recorded GPi single unit activity.

Figure 1

A, bar chart of mean normalised firing rate of each neuron over the time period 10–20 ms after the first inhibition (n = 42; zero corresponds here to tonic firing rate). B and C, means of PSTH data across the two identified clusters. B, mean of GPi neurons whose response to cortical impulse stimulation is biphasic (n = 6). C, mean of GPi neurons whose response to the same stimulus is triphasic (n = 36). Data from Tachibana et al. (2008). [Color figure can be viewed at wileyonlinelibrary.com]
