The neural correlates of topographical disorientation-a lesion analysis study

Olaf Blanke, Lukas Heydrich, Eva Blondiaux

Topographical disorientation refers to the selective inability to orient oneself in familiar surroundings. However, to date its neural correlates remain poorly understood. Here we use quantitative lesion analysis and a lesion network mapping approach in or ...

The role of population receptive field size and recurrent processing in learning to “de-crowd”

Michael Herzog, Bogdan Draganski, Ayberk Ozkirli, Maya Anna Jastrzebowska

In crowding, the perception of a target is impeded by surrounding clutter. While traditional models are feedforward and local, there is increasing behavioral and neural evidence for a critical role of recurrent processing across the visual hierarchy in cro ...

White matter hyperintensities at critical crossroads for executive function and verbal abilities in small vessel disease

Nathalie Heidi Meyer

The presence of white matter lesions in patients with cerebral small vessel disease (SVD) is among the main causes of cognitive decline. We investigated the relation between white matter hyperintensity (WMH) locations and executive and language abilities i ...

Spatially selective activation of the visual cortex via intraneural stimulation of the optic nerve

Silvestro Micera, Diego Ghezzi, Paola Vagni, Vivien Gaillet, Fiorenzo Artoni, Ariastity Mega Pratiwi, Dario Lipucci Di Paola

Retinal prostheses can restore a functional form of vision in patients affected by dystrophies of the outer retinal layer. Beyond clinical utility, prostheses for the stimulation of the optic nerve, the visual thalamus or the visual cortex could also serve ...

Dopaminergic modulation of cortical motor network lateralization

Michael Herzog, Maya Anna Jastrzebowska, Bogdan Draganski, Lester Melie Garcia, Renaud Marquis

Introduction Unilateral movements are primarily processed in contralateral cortical and subcortical areas and additionally in ipsilateral cerebellum, leading to an asymmetric pattern of neural activation. Decrease of lateralization is characteristic of agi ...

Visual-induced expectations modulate auditory cortical responses

Lukasz Grzeczkowski

Active sensing has important consequences on multisensory processing (Schroeder et al.,2010). Here, we asked whether in the absence of saccades, the position of the eyes and the timing of transient color changes of visual stimuli could selectively affect t ...

Post-Surgical Interval And Lesion Location Within The Limbic Thalamus Determine Extent Of Retrosplenial Cortex Immediate-Early Gene Hypoactivity

Guillaume Poirier

Four experiments examined the disruptive effects of selective lesions in limbic thalamic nuclei on retrosplenial cortex function, as characterized by striking changes in immediate-early gene activity. Major goals were to test the specificity of these retro ...
