The Coordinated Noninvasive Studies (CNS) Project. Phase 1
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 and/or substance abuse.
