Functional Localization of Visual Motion Area FST in Humans.

ABSTRACT: The fundus of the superior temporal sulcus (FST) in macaque monkeys is implicated in the processing of complex motion signals, yet a human homolog remains elusive. To better understand the neural mechanisms underlying the analysis of complex motion signals in humans, it is crucial to understand if and where a region homologous to FST exists. Here, we considered potential localizers and evaluated their effectiveness in delineating putative FST (pFST) from two nearby motion-sensitive areas, hMT and MST, in humans. Nine participants underwent fMRI scanning sessions with 2D and 3D motion localizers, as well as population receptive field (pRF) mapping. We observed consistent anterior and inferior activation relative to hMT and MST in response to stimuli that contained coherent 3D, but not 2D, m
