Research Abstract

It is well known that the higher-level dorsal stream integrates local motion signals from V1 into global motion. Thus, coherent motion stimuli will be able to use for evaluating the global motion defects. In addition, there are several types of global motion including radial optic flow (OF) and horizontal motion (HO). In this study, ERPs elicited by coherent OF and HO stimuli were recorded and analyzed in healthy young and old adults, and mild cognitive impairment patients. In the results, two major components (N170 and P200) were obtained in healthy young adults. N170 with V5/MT origin was evoked by both stimuli. In contrast, P200 with an IPL (BA 40) origin was elicited only by OF. These findings suggested that N170 was a nonspecific motion-related component originating from V5/MT, while P200 was an OF-specific component generated by the IPL. Therefore, a combined approach of ERPs using coherent motion (particularly OF) can be useful for discriminating MCI and AD patients from healthy old adults.
