Two distinct dorsal flows have been proposed: the inferior parietal (ventro-dorsal (v-d)) and superior parietal (dorso-dorsal (d-d)) streams. We aimed to elucidate how the two dorsal streams are altered in patients with amnestic mild cognitive impairment (aMCI) and AD. Thus, the psychophysical threshold measurements and visual event-related potentials (ERPs) were recorded in patients with aMCI and AD, and in…
