26 Multiple visual tasks can be performed on the same visual input, with different tasks presumably 27 engaging different neuronal populations. The modular layout of the visual system implies that specific 28 cortical regions carry more information about certain stimulus attributes than others. Thus, it is reasonable 29 to assume that decisions during a(More)
Performance in many visual tasks is impaired when observers attempt to divide spatial attention across multiple visual field locations. Correspondingly, neuronal response magnitudes in visual cortex are often reduced during divided compared with focused spatial attention. This suggests that early visual cortex is the site of capacity limits, where finite(More)
Early descriptions of floating limb behaviors in monkeys were associated with isolation rearing, a practice that ended more than two decades ago. The present authors named various forms of behaviors in which a leg is elevated for no apparent reason: "Floating Limb Suite" (FLS). Floating limb behaviors, identified in laboratory monkeys at the Washington(More)
INTRODUCTION There is substantial interest in the use of population receptive field (pRF) 1 modeling to examine cortical reorganization after vision loss. Our lab has been developing methods for quantifying bottom-up changes in population receptive fields that are independent from the effects of spatio-temporal BOLD nonlinearities and various top-down(More)
Adult female macaques (Macaca nemestrina) in the laboratory with alopecia from known or suspected overgrooming were subjects in a study evaluating effectiveness of a grooming device. The intervention evaluated was a paint roller on a metal bar hung on the cage, replaced weekly for 6 weeks. In a within-subjects design, 6 monkeys were randomly assigned to(More)
