Human awareness of left space may be disrupted by cerebral lesions to the right hemisphere (hemispatial neglect). Current knowledge on anatomical bases this complex syndrome is based results group studies that investigated primarily best known aspect syndrome, which visual neglect for near extrapersonal (or peripersonal) space. However, another component-neglect personal space-is more often associated with, than double-dissociated from, neglect, especially, in chronic patients. The present...
Abstract Functional magnetic resonance imaging was used to compare the neural correlates of three different types spatial coding, which are implicated in crucial cognitive functions our everyday life, such as visuomotor coordination and orientation topographical space. By manipulating requested reference during a task relative distance estimation, we directly compared viewer-centered, object-centered, landmark-centered coding same realistic 3-D information. Common activation found bilateral...
The retinotopic organization of a newly identified visual area near the midline in dorsalmost part human parieto-occipital sulcus was mapped using high-field functional magnetic resonance imaging, cortical surface-based analysis, and wide-field stimulation. This found all 34 subjects that were mapped. It represents contralateral hemifield both hemispheres subjects, with upper fields located anterior medial to areas V2/V3, lower slightly V3/V3A. contains representation center gaze distinct...
Cortical-surface-based functional Magnetic Resonance Imaging mapping techniques and wide-field retinotopic stimulation were used to verify the presence of pattern motion sensitivity in human area V6. Area V6 is highly selective for coherently moving fields dots, both at individual group levels even with a visual stimulus standard size. This localizer The wide stimuli here also revealed map middle temporal cortex (area MT/V5) surrounded by several polar-angle maps that resemble mosaic small...
Previous studies have indicated that largely overlapping parts of a complex, mainly fronto-parietal, neural network are activated during both observation and execution an action. If these two processes inextricably linked, increases activity contingent upon action should be found only for movements can actually performed. Using functional magnetic resonance imaging, we investigated whether possible biomechanically impossible fingers the same systems. Thirteen healthy subjects were scanned...
In macaque monkeys, V6A is a visuomotor area located in the anterior bank of POs, dorsal and to retinotopically-organized extrastriate V6 (Galletti et al., 1996). Unlike V6, represents both contra- ipsilateral visual fields broadly retinotopically organized 1999b). The contralateral lower field over-represented V6A. central 20°–30° mainly represented dorsally (V6Ad) periphery ventrally (V6Av), at border with V6. Both sectors contain arm movement-related cells, active during...
The optic flow generated when a person moves through the environment can be locally decomposed into several basic components, including radial, circular, translational and spiral motion. Since their analysis plays an important part in visual perception control of locomotion posture it is likely that some brain regions primate dorsal pathway are specialized to distinguish among them. aim this study explore sensitivity different types egomotion-compatible stimulations human motion-sensitive...
Abstract Neuroimaging studies have revealed two separate classes of category-selective regions specialized in optic flow (egomotion-compatible) processing and scene/place perception. Despite the importance both recognition to estimate changes position orientation within environment during self-motion, possible functional link between egomotion- scene-selective has not yet been established. Here we reanalyzed magnetic resonance images from a large sample participants performing well-known...
Recent research shows that emotional facial expressions impact behavioral responses only when their valence is relevant to the task. Under such conditions, threatening faces delay attentional disengagement, resulting in slower reaction times and increased omission errors compared happy faces. To investigate neural underpinnings of this phenomenon, we used functional magnetic resonance imaging record brain activity 23 healthy participants while they completed two versions go/no-go In emotion...
Abstract Because sensory systems use different spatial coordinate frames, cross‐modal integration and sensory–motor transformations must occur to build integrated representations. Multimodal neurons using non‐retinal body‐centred reference frames are found in the posterior parietal frontal cortices of monkeys. We used functional magnetic resonance imaging reveal regions human brain coordinates code position both visual somatic stimuli. Participants determined whether a visible vertical bar...
Abstract The perception of tactile stimuli on the face is modulated if subjects concurrently observe a being touched; this effect, termed visual remapping touch (VRT), maximum for observing one's own face. In present fMRI study, we investigated neural basis VRT effect. Participants in scanner received stimuli, near perceptual threshold, their right, left, or both cheeks. Concurrently, they watched movies depicting face, another person's ball that could be touched only approached by human...
