The neural basis of centre-surround interactions in visual motion processing [PDF]
, 2011 Perception of a moving visual stimulus can be suppressed or enhanced by surrounding context in adjacent parts of the visual field. We studied the neural processes underlying such contextual modulation with fMRI.

Understanding Mechanisms of Whole Brain and Regional Grey Matter Atrophy in Children With MOGAD
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To investigate the mechanisms driving whole brain and regional grey matter (GM) volume changes along with their clinical correlates in paediatric myelin oligodendrocyte glycoprotein antibody (MOG‐Ab)–associated disease (MOGAD). Methods One‐hundred‐nine paediatric MOGAD patients from two UK centres underwent MRI at attack nadir and ...

Neural Plasticity, 2022 Background. Visual symptoms are common in patients with migraine, even in interictal periods. The purpose was to assess the association between dynamic functional connectivity (dFC) of the visual cortex and clinical characteristics in migraine without ...

Identification of Dementia With Lewy Bodies by Skin Biopsy in Recent‐Onset Cognitive Impairment
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Immunofluorescence for phosphorylated alpha‐synuclein in skin biopsy samples is an emerging biomarker in synucleinopathies comprising Dementia with Lewy bodies. In this pilot study, 19 patients with recent‐onset (≤ 18 months) cognitive impairment underwent skin biopsy at baseline, with follow‐up clinical re‐evaluation.

Emotional modulation of visual cortex activity: A functional nearinfrared spectroscopy study [PDF]
, 2009 Functional neuroimaging and electroencephalography reveal emotional effects in early visual cortex. Here, we used fNIRS to examine haemodynamic responses evoked by neutral, positive and negative emotional pictures, matched for brightness, contrast, hue,

Dynamic architecture of the visual cortex
Brain Research, 1970 Several aspects of the organization of the visual cortex in the mouse have been examined in Golgi preparations. Special attention has been devoted to the afferent systems innervating the basal dendrites of pyramidal cells of layers III and V. A computer analysis using matrix algebra of the projected dendritic field of the basal and apical-collateral ...

Thalamic nuclei convey diverse contextual information to layer 1 of visual cortex
Nature Neuroscience, 2015 Sensory perception depends on the context in which a stimulus occurs. Prevailing models emphasize cortical feedback as the source of contextual modulation.
