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...

Visual mental imagery is a complex process that may be influenced by the content of images. Neuropsychological evidence from patients with hemineglect suggests in domain environments and objects represented separately selectively affected brain lesions. In present study, we used functional magnetic resonance imaging (fMRI) to assess possibility neural segregation among images depicting parts an object, environment (imagined first-person perspective), geographical map, using both mass...

KEEPING ORIENTED IN THE ENVIRONMENT IS A MULTIFACETED ABILITY THAT REQUIRES KNOWLEDGE OF AT LEAST THREE PIECES INFORMATION: one's own location ("place") and orientation ("heading") within the environment, which in environment one is looking at ("view"). We used functional magnetic resonance imaging (fMRI) humans to examine neural signatures of these information. Participants were scanned while viewing snapshots varied for place, view heading a virtual room. observed adaptation effects,...

Abstract To plan movements toward objects our brain must recognize whether retinal displacement is due to self‐motion and/or object‐motion. Here, we aimed test motion areas are able segregate these types of motion. We combined an event‐related functional magnetic resonance imaging experiment, mapping techniques, and wide‐field stimulation study the responsivity motion‐sensitive pure self‐ object‐motion conditions during virtual movies a train running within realistic landscape. observed...

The parieto-frontal circuit underlying grasping, which requires the serial involvement of anterior intraparietal area (aIPs) and ventral premotor cortex (PMv), has been recently extended enlightening role dorsal (PMd). supplementary motor (SMA) also suggested to encode grip force for grasping actions; furthermore, both PMd SMA are known play a crucial in imagery. Here, we aimed at assessing dynamic couplings between left aIPs, PMv, PMd, primary (M1) by comparing executed imagined right-hand...

Abstract Monkey neurophysiology and human neuroimaging studies have demonstrated that passive viewing of optic flow stimuli activates a cortical network temporal, parietal, insular, cingulate visual motion regions. Here, we tested whether the areas involved in processing signals simulating self‐motion are also activated by active lower limb movements, hence likely guiding locomotion. To this aim, used combined approach task‐evoked activity resting‐state functional connectivity fMRI. We...

Individuals vary widely in their ability to orient and navigate within the environment. Previous neuroimaging research has shown that hippocampus (HC) scene-responsive regions (retrosplenial complex [RSC] parahippocampal gyrus/parahippocampal place area [PPA]) were crucial for spatial orienting navigation. Resting-state functional connectivity a self-reported questionnaire of navigational used examine hypothesis pattern reciprocal connections between these reflects individual differences It...

Abstract The ability to detect and assess world‐relative object‐motion is a critical computation performed by the visual system. This computation, however, greatly complicated observer's movements, which generate global pattern of motion on retina. How system implements this poorly understood. Since we are potentially able moving object if its differs in velocity (or direction) from expected optic flow generated our own motion, here manipulated relative between observer within stationary...

Abstract Mental imagery and visual perception rely on the same content‐dependent brain areas in high‐level cortex (HVC). However, little is known about dynamic mechanisms these during perception. Here we disentangled local inter‐regional underlying HVC hippocampus (HC), a key region for memory retrieval imagery. Nineteen healthy participants watched or imagined familiar scene face fMRI acquisition. The neural code landmarks faces was distributed across HC, although with different...

Central post-stroke pain is a neuropathic syndrome characterized by intolerable contralesional and, in rare cases, somatic delusions. To date, there limited evidence for the effective treatments of this disease. Here we used caloric vestibular stimulation to reduce and somatoparaphrenia 57-year-old woman suffering from central pain. Resting-state functional magnetic resonance imaging was assess neurological effects treatment. Following observed impressive improvements motor skills, pain, In...

Visual cues coming from the lower visual field (VF) play an important role in guidance of upper and limb movements. A recently described region situated dorsomedial parietal cortex, area hPEc (Pitzalis et al. NeuroImage 202:116092, 2019), might have a integrating visually derived information with somatomotor signals to guide interaction environment. In macaque, it has been demonstrated that PEc receives mostly but, date, there no systematic investigation VF preference newly defined human...

Neuroimaging studies associate specific functional roles to distinct brain regions investigating separate cognitive processes using dedicated tasks. For example, both correlative (i.e., fMRI) and causal TMS) approaches it has been shown the involvement of intra-parietal sulcus (IPS), as part dorsal attention network, in spatial attentional tasks well importance angular gyrus (AG), default mode during selection relevant information semantic memory. Nonetheless, our daily life memory are...
