Figure 2
From: Response of SI cortex to ipsilateral, contralateral and bilateral flutter stimulation in the cat
Surface plots of absorbance evoked in SI by contralateral, ipsilateral, and bilateral stimulation. Data displayed is a subset of the data displayed in Figure 1. Region of interest is indicated by the dashed box shown in the OIS image (top left). Orientation of the selected region is indicated by X (medial-lateral) and Y (anterior-posterior) labels on the dashed box and axes (in ipsilateral map). Cortical space along X and Y axes is measured in mm. Z axis is absorbance which is represented by both the height of the graphic as well as the color indicated by the color bar to the right. Surface plots represent absorbance values within the ROI at 5 seconds after stimulus onset and demonstrate that 1)response in SI to ipsilateral stimulation is small or nonexistent and, 2)magnitude of evoked absorbance in response to contralateral stimulation is slightly larger than the response evoked by bilateral stimulation.
