Autor: Jelle A van Dijk, Maartje C de Jong, Gio Piantoni, Alessio Fracasso, Mariska J Vansteensel, Iris I A Groen, Natalia Petridou, Serge O Dumoulin

Publikováno v: PLoS ONE, Vol 17, Iss 8, p e0272087 (2022)

Numerosity is the set size of a group of items. Numerosity perception is a trait shared across numerous species. Numerosity-selective neural populations are thought to underlie numerosity perception. These neurons have been identified primarily using

Image identification from brain activity using the population receptive field model.

Autor: Wietske Zuiderbaan, Ben M Harvey, Serge O Dumoulin

Publikováno v: PLoS ONE, Vol 12, Iss 9, p e0183295 (2017)

A goal of computational models is not only to explain experimental data but also to make new predictions. A current focus of computational neuroimaging is to predict features of the presented stimulus from measured brain signals. These computational

Role of the parahippocampal cortex in memory for the configuration but not the identity of objects: converging evidence from patients with selective thermal lesions and fMRI

Autor: Veronique D Bohbot, John J.B. Allen, Alain eDagher, Serge O Dumoulin, Alan eEvans, Michael ePetrides, Miroslav eKalina, Katerina eStepankova, Lynn eNadel

The parahippocampal cortex and hippocampus are brain structures known to be involved in memory. However, the unique contribution of the parahippocampal cortex remains unclear. The current study investigates memory for object identity and memory of th

Cortical Connective Field Estimates from Resting State fMRI Activity

Autor: Nicolás eGravel, Ben eHarvey, Barbara eNordhjem, Koen V. Haak, Serge O Dumoulin, Remco eRenken, Branislava eĆurčić-Blake, Frans W. Cornelissen

Publikováno v: Frontiers in Neuroscience, Vol 8 (2014)

One way to study connectivity in visual cortical areas is by examining spontaneous neural activity. In the absence of visual input, such activity remains shaped by the underlying neural architecture and, presumably, may still reflect visuotopic organ

Decreased fixation stability of the preferred retinal location in juvenile macular degeneration.

Autor: Richard A I Bethlehem, Serge O Dumoulin, Edwin S Dalmaijer, Miranda Smit, Tos T J M Berendschot, Tanja C W Nijboer, Stefan Van der Stigchel

Publikováno v: PLoS ONE, Vol 9, Iss 6, p e100171 (2014)

Macular degeneration is the main cause for diminished visual acuity in the elderly. The juvenile form of macular degeneration has equally detrimental consequences on foveal vision. To compensate for loss of foveal vision most patients with macular de

Macular degeneration affects eye movement behaviour during visual search

Autor: Stefan eVan Der Stigchel, Richard A.I. eBethlehem, Barrie P. eKlein, Tos T.J.M. eBerendschot, Tanja eNijboer, Serge O Dumoulin

Publikováno v: Frontiers in Psychology, Vol 4 (2013)

Patients with a scotoma in their central vision (e.g. due to macular degeneration, MD) commonly adopt a strategy to direct the eyes such that the image falls onto a peripheral location on the retina. This location is referred to as the preferred reti

Cortico-Cortical Receptive Field Estimates in Human Visual Cortex

Autor: Koen V Haak, Jonathan Winawer, Ben M Harvey, Remco Renken, Serge O Dumoulin, Brian A Wandell, Frans W Cornelissen

Publikováno v: i-Perception, Vol 3 (2012)

Human visual cortex comprises many visual areas that contain a map of the visual field (Wandell et al 2007, Neuron 56 , 366–383). These visual field maps can be identified readily in individual subjects with functional magnetic resonance imaging (f

Population Receptive Field Properties from fMRI and Electrocorticography in Striate and Extrastriate Cortex of the Same Subject

Autor: Ben Mark Harvey, Mariska J Vansteensel, Chris H Dijkerman, Martine J E van Zandvoort, Cyrille Ferrier, Natalia Petridou, Frans S S Leijten, Nick F Ramsey, Serge O Dumoulin

Publikováno v: i-Perception, Vol 3 (2012)

Population receptive field (pRF) modelling reconstructs the properties of visually responsive neuronal populations, typically using fMRI in humans. However, fMRI is an indirect measure of neural activity. Electrocorticography (ECoG) measures electric

Objective Neurons cluster into sub-millimeter spatial structures and neural activity occurs at millisecond resolutions; hence, ultimately, high spatial and high temporal resolutions are required for functional MRI. In this work, we implemented a spin
