Neural Computation of Pattern Motion : Modeling Stages of Motion Analysis in the Primate Visual Cortex

This book describes a neurally based model, implemented as a connectionist network, of how the aperture problem is solved. How does the visual system compute the global motion of an object from local views of its contours? Although this important pro

The involvement of left inferior frontal and middle temporal cortices in word production unveiled by greater facilitation effects following brain damage

Autor: Grégoire Python, Bertrand Glize, Marina Laganaro

Publikováno v: Neuropsychologia, vol. 121, pp. 122-134

In stroke-induced aphasia, left hemispheric lesions generally disturb the word production network. The left inferior frontal gyrus (LIFG) and the left middle temporal gyrus (LMTG) are involved in word production, but their respective contribution rem

Real and predicted influence of image manipulations on eye movements during scene recognition

Autor: Harding, G., Bloj, M.

In this paper, we investigate how controlled changes to image properties and orientation affect eye movements for repeated viewings of images of natural scenes. We make changes to images by manipulating low-level image content (such as luminance or c

Population receptive field (pRF) mapping based on functional magnetic resonance imaging (fMRI) is an ideal method for obtaining detailed retinotopic information. One particularly promising application of pRF mapping is the estimation and quantificati

Unconscious categorization of sub-millisecond complex images

Can people categorize complex visual scenes unconsciously? The possibility of unconscious perception remains controversial. Here, we addressed this question using psychophysical methods applied to unmasked visual stimuli presented for extremely short

Brain mechanisms for perceiving illusory lines in humans

Autor: Jean-François Knebel, Jacques Anken, Ruxandra I. Tivadar, Micah M. Murray

Publikováno v: NeuroImage, vol. 181, pp. 182-189

Illusory contours (ICs) are perceptions of visual borders despite absent contrast gradients. The psychophysical and neurobiological mechanisms of IC processes have been studied across species and diverse brain imaging/mapping techniques. Nonetheless,

Visual search accelerates during adolescence

We studied changes in visual-search performance and behavior during adolescence. Search performance was analyzed in terms of reaction time and response accuracy. Search behavior was analyzed in terms of the objects fixated and the duration of these f

Recent studies have shown that it is feasible to record simultaneously intracerebral EEG (icEEG) and functional magnetic resonance imaging (fMRI) in patients with epilepsy. While it has mainly been used to explore the hemodynamic changes associated w

Individuals with 22q11.2 deletion syndrome (22q11.2DS) are impaired at exploring visual information in space; however, not much is known about visual form discrimination in the syndrome. Thirty-five individuals with 22q11.2DS and 41 controls complete
