There are important developmental changes occurring during infancy in visual cortical structures that underlie higher-order perceptual abilities. Using high-density electrophysiological recording techniques, the present study aimed to examine the development of visual mechanisms, during the first year of life, associated with texture segregation. Forty-two(More)
This study investigated the redundant target effect (RTE) in partial split-brain (anterior section sparing the splenium), total split-brain, and neurologically intact individuals. All completed an RTE protocol in which targets were presented on the midline or in an inter- or intrahemispheric manner. Stimuli of different nature (luminance, equiluminant(More)
Visual evoked potentials (VEPs) were recorded to textures segregated by gradients in orientation or motion. Recordings were obtained in traumatic brain-injured (TBI) subjects and in normal controls. We analyzed both the low-level VEPs (llVEPs) evoked by homogenous stimuli, as well as the components associated with texture segregation (tsVEP) obtained(More)
OBJECTIVES This article reviews research, policy and programming in Australia, Canada and the US on the child welfare response to EDV. METHOD The review draws on searches of standard research databases, interviews with researchers and practitioners, and the authors' own research. RESULTS Although EDV is underreported, across studies 7% to 23% of youths(More)
OBJECTIVE This article critically assesses and reviews analyses derived from three cycles of the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS) published between 2001 and October 2011. METHODS Articles were retrieved from the Public Health Agency of Canada's data request records, which tracked database access and ensuing publications.(More)
This study investigated interhemispheric transfer in ten normal, four anterior-, and four totally-split-brain individuals, through measures of manual asynchrony and bimanually-recorded crossed-uncrossed difference (CUD). The CUD relied on the difference between crossed and uncrossed responses whereas the asynchrony measure relied on the reaction time(More)
Research on split-brain individuals started to flourish approximately 70 years ago and has since then significantly contributed to our understanding of hemispheric specialization. This overview aims to capture the essential of its progress. Amongst other things, the disconnection syndrome is exposed through a description of its manifestations on sensory,(More)
