Figure 2.

Spikelet-related variance increases with CS synchrony among PCs within a single zebrin band. (A) Plotting of electrode array from one experiment onto the zebrin map of crus IIa. Each black dot represents the position of an electrode in the array. Ellipses indicate the two PC groups whose CS activity was analyzed from this experiment. White-filled circles indicate locations of dye injections that were used to align the recording array with the zebrin map. (B) Plots of average variance as a function of group synchrony for the two PCs indicated by arrows in (A). (C) Average variance for the lowest and highest synchrony levels for the population. Each circles represents data from one PC, bars indicate population averages, and error bars are one SD.
