Distinct contributions by frontal and parietal cortices support working memory
http://biorxiv.org/content/early/2017/01/31/104430 [PDF] Although subregions of frontal and parietal cortex both contribute and coordinate to support working memory (WM) functions, their distinct contributions remain elusive. Here, we demonstrate that perturbations to topographically organized…
SfN 2016: Visual field maps constrain working memory precision
http://www.abstractsonline.com/pp8/index.html#!/4071/presentation/18729 Working memory (WM) suffers from severe capacity limitations that vary greatly both between individuals and across the lifespan. Recent psychophysical work suggests that WM is a finite resource, and that this…
Visual field map clusters in human frontoparietal cortex
http://biorxiv.org/content/early/2016/10/27/083493 [PDF] The visual neurosciences have made enormous progress in recent decades, in part because of the ability to drive visual areas by their sensory inputs, allowing researchers to reliably define visual…
Human parietal cortex lesions impact the precision of spatial working memory
http://jn.physiology.org/content/early/2016/06/10/jn.00380.2016 [PDF] The neural mechanisms that support working memory (WM) depend on persistent neural activity. Within topographically organized maps of space in dorsal parietal cortex, spatially selective neural activity persists during WM…
SFN 2014: Visual field maps in human association cortices
Recently, topographic maps in human frontal and parietal cortex were discovered using modified versions of the standard traveling wave method for mapping early visual cortex. The standard traveling wave method is effective…
