Figure 2

(a,b) The comparison of the signal amplitude and the latency of the intrinsic signals evoked by stimulating contralateral whiskers in the ischemic and healthy hemispheres. The yellow rectangle and colored bars show the stimulation period and the latency of the responses, respectively. The latency of signal in healthy and stroke hemisphere are shown in blue and red bars, respectively. The comparison between the spatial extent of the intrinsic response evoked by stimulating contralateral whiskers is shown in the motor (c,d) and somatosensory (e,f) cortices. c and e are related to the stroke hemisphere and (d,f) are related to the healthy hemisphere. The regions in red color illustrate the areas activated in response to stimulation. The calculations are done for every 10 × 10-pixel block and the coordinates of the brain areas under study and the spatial scale are shown in this figure. The waveforms of the expected responses used in the ‘pattern detection algorithm’ in the panels (c–f) are shown in the upper left corners of these panels.
