Electroencephalogram of an unanaesthetized rabbit taken 3 weeks after production of an ethyl chloride lesion in the area designated by cross hatching. Discharges originating in the primary lesion (electrode 2) and in the secondary region (electrode 7) are unrelated in time of occurrence. Note also that there is some depression of activity in electrodes just posterior to the primary lesion while this is not true of electrodes posterior to the mirror focus. Calibration: 50 microvolts and i Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Council for International Organizations of Medical Sciences; Fessard, A.
