Document Summary
Two weeks before brain surgery, went to hospital for series of tests. Had brain tumor on right auditory-vestibular cranial nerve. Had to have it excised (cut out) Balance (vestibular function) was tested by injecting cold water into his ear. Hearing in right ear was poor - right vestibular nerve was barely functioning. One last test - skin on right cheek was lightly pricked while eeg responses of somatosensory cortex were recorded from his scalp. One main risk of removing tumors on auditory-vestibular cranial nerve is damaging the facial cranial nerve, and that would make the right side of your face sag. Methods of visualizing and stimulating the living human brain. Before 1970s - biopsychological research was impeded by the inability to obtain images of the organ of primary interest - human brain. Conventional x-ray photography - useless for this purpose.
