Figure 5.
Comparison of neural and behavioral data. For the behavioral data, the horizontal axis shows time relative to saccade onset, and the right vertical axis indicates normalized contrast sensitivity as taken from the study by Diamond et al. (2000). Neuronal data were shifted along the time axis to correct for response and processing latencies (see Results) and represent neuronal excitability (left vertical axis) of the MT and MST populations (cyan and blue curves, respectively) and the VIP population (red curve). The time course of neuronal excitability in all three motion areas of the macaque shows a good qualitative match with the time course of perceptual loss of sensitivity around saccades in human subjects.
