Blindsight refers to the ability of some patients with destruction of the primary visual cortex (V1) to respond to stimuli presented in their clinically blind visual field despite lack of visual awareness. Here we tested a rare and well-known patient

Early Human Visual Cortex Encodes Surface Brightness Induced by Dynamic Context
Autor: Vincent van de Ven, Rainer Goebel, Peter De Weerd, Bert Jans
Publikováno v: Journal of Cognitive Neuroscience, 24(2), 367-377. MIT Press
Visual scene perception owes greatly to surface features such as color and brightness. Yet, early visual cortical areas predominantly encode surface boundaries rather than surface interiors. Whether human early visual cortex may nevertheless carry a

Dynamic brightness induction in V1: Analyzing simulated and empirically acquired fMRI data in a 'common brain space' framework

Computational neuromodeling may help to further our understanding of how empirical neuroimaging findings are generated by underlying neural mechanisms. Here, we used a simple computational model that simulates early visual processing of brightness ch

Time-limited consolidation and task interference: no direct link
Autor: Bert Jans, Marin Been, P De Weerd
Publikováno v: Journal of Neuroscience, 31(42), 14944-14951. Society for Neuroscience
Perceptual skills improve with daily practice (Fahle and Poggio, 2002; Fine and Jacobs, 2002). Practice induces plasticity in task-relevant brain regions during an “offline” consolidation period thought to last several hours, during which initial

Visual spatial attention to multiple locations at once: the jury is still out
Autor: Peter De Weerd, Judith C. Peters, Bert Jans
Publikováno v: Psychological Review, 117(2), 637-684. American Psychological Association
Psychological Review, 117, 637-682. American Psychological Association
Although in traditional attention research the focus of visual spatial attention has been considered as indivisible, many studies in the last 15 years have claimed the contrary. These studies suggest that humans can direct their attention simultaneou

A non-trivial connection for the metric-affine Gauss–Bonnet theory in D = 4
Autor: Bert Janssen, Alejandro Jiménez-Cano, José Alberto Orejuela
Publikováno v: Physics Letters B, Vol 795, Iss , Pp 42-48 (2019)
We study non-trivial (i.e. non-Levi-Civita) connections in metric-affine Lovelock theories. First we study the projective invariance of general Lovelock actions and show that all connections constructed by acting with a projective transformation of t

Projective symmetries and induced electromagnetism in metric-affine gravity
Autor: Bert Janssen, Alejandro Jiménez-Cano
Publikováno v: Physics Letters B, Vol 786, Iss , Pp 462-465 (2018)
We present a framework in which the projective symmetry of the Einstein–Hilbert action in metric-affine gravity is used to induce an effective coupling between the Dirac lagrangian and the Maxwell field. The effective U(1) gauge potential arises as

On the (non-)uniqueness of the Levi-Civita solution in the Einstein–Hilbert–Palatini formalism
Autor: Antonio N. Bernal, Bert Janssen, Alejandro Jiménez-Cano, José Alberto Orejuela, Miguel Sánchez, Pablo Sánchez-Moreno
Publikováno v: Physics Letters B, Vol 768, Iss C, Pp 280-287 (2017)
We study the most general solution for affine connections that are compatible with the variational principle in the Palatini formalism for the Einstein–Hilbert action (with possible minimally coupled matter terms). We find that there is a family of
