Normal grasping actions towards real objects are target-directed, mediated via real-time visuomotor control, and provide haptic feedback. Studies of visual form agnosic patient DF suggest that pantomime (pretend) grasps are different; they recruit the visual Ventral stream (inferior temporal cortex), while normal grasps recruit the visual Dorsal stream (posterior parietal cortex). This functional duality underlies the eponymous Two Visual Systems Hypothesis (TVSH). Critics of the TVSH emphasize the multimodal nature of sensory processing and propose a model, termed the Common Source Hypothesis (CSH), of a single more localized system. Existing studies of natural prehension during interleaved trials of normal and …

Concussions are a prevalent injury that affect a wide range of individuals. Commonly seen amongst individuals who play contact sports, there are many underlying factors that doctors and clinicians have yet to understand which include properties such as proper diagnosis standards or lasting impacts. In this study, we look at those impacts by using electroencephalographic (EEG) measures to study the changes in event related potentials (ERPs) associated with sensory gating and how this cognitive property is affected in those who have a self-reported concussion. Here we show that a visual attention and gating mechanism exists in both populations (control and …
