Open AccessLong Covid: where we stand and challenges ahead
Post-acute sequelae of SARS-CoV-2 (PASC), also known as Post-Covid Syndrome, and colloquially as Long Covid, has been defined as a constellation of signs and symptoms which persist for weeks or months after th...

Open AccessWhite matter deficits correlate with visual motion perception impairments in dyslexic carriers of the DCDC2 genetic risk variant
Motion perception deficits in dyslexia show a large intersubjective variability, partly reflecting genetic factors influencing brain architecture development. In previous work, we have demonstrated that dyslex...

Bariatric surgery restores visual cortical plasticity in nondiabetic subjects with obesity
Obesity leads to changes in synaptic plasticity. We aimed at investigating the impact of bariatric surgery (RYGB) on visual neural plasticity (NP) and its relationship with the main gut peptides, leptin, and b...

Open AccessThe visual white matter connecting human area prostriata and the thalamus is retinotopically organized
The human visual system is capable of processing visual information from fovea to the far peripheral visual field. Recent fMRI studies have shown a full and detailed retinotopic map in area prostriata, located...

Open AccessBehavioural oscillations in visual orientation discrimination reveal distinct modulation rates for both sensitivity and response bias
Perception is modulated by ongoing brain oscillations. Psychophysical studies show a voluntary action can synchronize oscillations, producing rhythmical fluctuations of visual contrast sensitivity. We used sig...

Open AccessCortical BOLD responses to moderate- and high-speed motion in the human visual cortex
We investigated the BOLD response of visual cortical and sub-cortical regions to fast drifting motion presented over wide fields, including the far periphery. Stimuli were sinusoidal gratings of 50% contrast m...

Open AccessAutism is associated with reduced ability to interpret gras** actions of others
We investigated the ability of children with ASD to discriminate a small cylinder from a large cube by observing a point-light movie of an actor gras** the object, either from an allocentric or egocentric vi...

Open AccessSpatial localization of sound elicits early responses from occipital visual cortex in humans
Much evidence points to an interaction between vision and audition at early cortical sites. However, the functional role of these interactions is not yet understood. Here we show an early response of the occip...

Visual information from observing gras** movement in allocentric and egocentric perspectives: development in typical children
Development of the motor system lags behind that of the visual system and might delay some visual properties more closely linked to action. We measured the developmental trajectory of the discrimination of obj...

Article
Open AccessPerceived visual time depends on motor preparation and direction of hand movements
Perceived time undergoes distortions when we prepare and perform movements, showing compression and/or expansion for visual, tactile and auditory stimuli. However, the actual motor system contribution to these...

Visual mislocalization during saccade sequences
Visual objects briefly presented around the time of saccadic eye movements are perceived compressed towards the saccade target. Here, we investigated perisaccadic mislocalization with a double-step saccade par...

Spatial maps for time and motion
In this article, we review recent research studying the mechanisms for transforming coordinate systems to encode space, time and motion. A range of studies using functional imaging and psychophysical technique...

Auditory dominance over vision in the perception of interval duration
The “ventriloquist effect” refers to the fact that vision usually dominates hearing in spatial localization, and this has been shown to be consistent with optimal integration of visual and auditory signals (Al...

Spatiotopic selectivity of BOLD responses to visual motion in human area MT
Many neurons in the monkey visual extrastriate cortex have receptive fields that are affected by gaze direction. In humans, psychophysical studies suggest that motion signals may be encoded in a spatiotopic fa...
