Abstract:

The CNS Project combines several noninvasive methods for monitoring brain structure and function in a test battery. Phase One 1988-1991 focussed on neuroanatomical and neurophysiological correlates of behavioral ear advantages for two sets of complex sounds. Fifteen subjects neurologically normal according to conventional standards were tested with dichotic listening 2 measures, NM 2 measures, evoked potentials 2 measures, and qEEG 4 measures. One subject was also tested under similar conditions with PET. Results indicated 1 Each individual had a distinct sidedness bias articulated in terms of a combination of anatomical and physiological variables, 2 These individual patterns cut across conventional categories such as gender and handedness, 3 In some of the subjects, these CNS profiles comprised internally consistent patterns of asymmetries linking subcortical physiology, cortical anatomy and cortical physiology, 4 In others, departures from such consistency signalled evidence of a variety of subtle neuropathologies, such as stuttering, mild learning disorder, central auditory dysfunction, or a history of hyperactivity andor substance abuse.
