One class of optic flow is spiral motion, defined by the angle between a local vector direction and the direction of the steepest increase in local speed. By discriminating among such angles, an organism could discern between different flow patterns and effectively interact with the environment. In primates, spiral-selective neurons in medial superior temporal area are thought to provide the substrate for this ability. We found that these cells show higher discrimination thresholds than found behaviorally in humans, suggesting that when discriminating spiral motions the brain integrates information across many of these neurons to achieve its high perceptual performance."],["dc.identifier.doi","10.1097/wnr.0b013e32833312c7"],["dc.identifier.gro","3151561"],["dc.identifier.pmid","19957382"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8370"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0959-4965"],["dc.title","Comparing neuronal and behavioral thresholds for spiral motion discrimination"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

In this study, we use functional imaging to demonstrate that a subregion of MT/V5 is more strongly activated by unidirectional motion with speed gradients than by other motion patterns. Our results suggest that like the monkey homolog middle temporal area (MT), human MT/V5 contains neurons selective for the processing of speed gradients. Such neurons may constitute an intermediate stage of processing between neurons selective for the average speed of unidirectional motion and neurons selective for different combinations of speed gradient and different motion directions such as expanding optical flow patterns."],["dc.identifier.doi","10.1097/00001756-200504040-00004"],["dc.identifier.gro","3151545"],["dc.identifier.pmid","15770147"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8354"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0959-4965"],["dc.title","Selectivity for speed gradients in human area MT/V5"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
