Ready…Go: Amplitude of the fMRI Signal Encodes Expectation of Cue Arrival Time

Figure 5

Evidence for an expectation-dependent fMRI signal generalizes to an auditory ready-go experiment.

(A) Participants viewed a blank screen. A brief double beep served as the ready signal, and a brief single beep served as the go signal. (B) As in the visual condition (Figure 1), longer readiness periods correlate with higher post-go fMRI signal (p-values of the correlation inset). Solid line, data from the auditory experiment. For comparison, the dashed line shows the fMRI results from the visual experiment (Figure 1). Error bars SEM.
