Comparison of average percentage BOLD signal changes in response to nociceptive heat stimulation within parasylvian areas across animals. A–C, E–F. Plots of average % BOLD signal changes derived from contralateral (black lines) and corresponding ipsilateral (red lines) regions. Time courses obtained from control regions are plotted as gray lines. Error bars indicate standard errors. The 24 sec stimulus duration period is shown by the pale orange background block in each plot. *: magnitude difference is significant at p < 0.05. **: magnitude difference is significant at p < 0.001. &: magnitude of undershoot difference is significant at p < 0.01. D. Comparison of BOLD signal changes among parasylvian areas: bilateral pIns (solid and dash red lines), S2/PV (solid and dash green lines), Ri (solid and dash blue lines), and contralateral Ins (orange line). X-axis: time in image volume, one volume = 1.5 sec. Light orange background blocks indicate the stimulus duration of 24 sec.
