Optimal Control of Saccades by Spatial-Temporal Activity Patterns in the Monkey Superior Colliculus
Figure 4
Burst magnitude across the SC motor map.
Three different activity measures were used to quantify the magnitude of the saccade-related bursts of SC neurons for movements towards the center of their movement field as a function of their rostral-to-caudal location in the SC motor map: A) number of spikes in the burst, B) mean firing rate and C) peak spike density. Cells were selected for having at least five saccades into the center of their movement field (within 0.5⋅σmf). Highlighted cells (asterisks) in four clusters of cells (dashed circles) were selected for producing ∼18 spikes for their preferred saccade (c.f., Fig. 5). Linear regression lines (solid) were fitted to the data from all n = 103 cells.
