Figure 2: Nonlinear amplitude modulation of the trial response across stimulus durations in each ROI.

Figure 2:

A) Schematic of parameter estimation from the trial response. B) Area of the trial response for each ROI and stimulus duration shows a nonlinearity in which shorter stimuli elicit proportionally larger responses. Area is normalized to the value of the 4 s stimulus. C) The peak amplitude of the trial response declines with shorter stimulus duration in each region. For the longest stimulus, V1 has larger responses than SC, but for the shortest stimulus there is no significant difference across regions. Error bars indicate 95% confidence intervals drawn from bootstrap across subjects (n=23 subjects).
