Repeated apneas are associated with severe hypoxemia that may ultimately lead to loss of consciousness in some breath-hold divers. Despite increasing number practitioners, the relationship between apnea-induced hypoxia and neurocognitive functions is still poorly understood sport free diving. To shed light onto this phenomenon, we examined impact long-term diving training on attentional processing, short-term memory, mnesic executive functions. Thirty-six men matched for age, height, weight...
The relationship between posttraumatic stress disorder (PTSD) and focal epilepsy is poorly understood. It has been hypothesized that there a complex reciprocal potential reinforcement of the symptoms each condition. In this study, we investigated whether are PTSD-specific brain changes in temporal lobe (TLE). Brain fluorodeoxyglucose positron emission tomography (PET) metabolism was compared controls two groups TLE patients: one group 15 patients fulfilling criteria for diagnosis PTSD...
The perceptual salience and semantic relevance of objects for the meaning a scene were evaluated with multiple criteria then manipulated in change-detection experiment that used an original combination one-shot tachistoscopic divided-visual-field paradigms to study behavioural hemispheric asymmetry. Coloured drawings depicted meaningful situations presented centrally very briefly (120 ms) only changes lateralised by adding object right or left visual hemifield. High high improved both...
Abstract Visual categorization improves when object-context associations in scenes are semantically consistent, thus predictable from schemas stored long-term memory. However, it is unclear whether this due to differences early perceptual processing, matching of memory representations or later stages response selection. We tested these three concurrent explanations across five experiments. At each trial, participants had categorize a scene context and an object briefly presented within the...
Age-related differences in visual search have been extensively studied using simple item arrays, showing an attentional decline. Little is known about how aging affects guidance during more complex scenes. To study this issue, we analyzed eye-movement behavior realistic scene search. We examined age-related top-down guidance, manipulating target template specificity (picture vs. word cue) and target-scene semantic consistency (consistent inconsistent), bottom-up perceptual salience (high...
BACKGROUND: Breath-hold (BH) training over several years may result in mild but persistent neurocognitive impairment. Paradoxically, the acute effects of repeated BH generating intermittent hypoxia on functions are still poorly understood. Therefore, we decided to examine impact five-repeated maximal attention, processing speed, and reasoning abilities.METHODS: Thirty six men separated 3 groups (12 elite divers: EBHD; 12 novice NBHD; non CTL) performed before after 5 BHs, neuropsychological...
Visual search is a crucial task in daily life, but Alzheimer's disease (AD) it has usually been investigated using simple arrays. Here, we used scenes depicting real environments and studied the time course of attentional guidance.
Alzheimer's disease (AD) is a progressive neurodegenerative disorder that affects the corpus callosum (CC), which plays key role in interhemispheric coupling high-demand conditions. Using 3D callosal measurements and letter-matching paradigm, this 2-part study investigated neural substrate of individuals with AD or amnestic mild cognitive impairment (a-MCI) age-matched healthy (HC).Thirty-three right-handed participants were MRI scanned to measure volume CC 5 sections. In Study 1, AD, a-MCI,...
Aim: Praxis assessment in children with developmental coordination disorder (DCD) is usually based on tests of adult apraxia, by comparing across types gestures and input modalities. However, the cognitive models praxis processing are rarely used a comprehensive critical interpretation. These generally involve two systems: conceptual system production system. Heterogeneity deficits consistently reported DCD, involving other skills such as executive or visual-perceptual visuospatial...
