Effective Connectivity of Depth-Structure–Selective Patches in the Lateral Bank of the Macaque Intraparietal Sulcus
Premereur, Elsie; Van Dromme, Ilse C.; Romero, Maria C.; Vanduffel, Wim; Janssen, Peter (Public Library of Science, 2015)Extrastriate cortical areas are frequently composed of subpopulations of neurons encoding specific features or stimuli, such as color, disparity, or faces, and patches of neurons encoding similar stimulus properties are ... -
The Extraction of Depth Structure from Shading and Texture in the Macaque Brain
Nelissen, Koen; Joly, Olivier; Durand, Jean-Baptiste; Todd, James T.; Vanduffel, Wim J.M.; Orban, Guy A. (Public Library of Science, 2009)We used contrast-agent enhanced functional magnetic resonance imaging (fMRI) in the alert monkey to map the cortical regions involved in the extraction of 3D shape from the monocular static cues, texture and shading. As ... -
The impact of orientation filtering on face-selective neurons in monkey inferior temporal cortex
Taubert, Jessica; Goffaux, Valerie; Van Belle, Goedele; Vanduffel, Wim; Vogels, Rufin (Nature Publishing Group, 2016)Faces convey complex social signals to primates. These signals are tolerant of some image transformations (e.g. changes in size) but not others (e.g. picture-plane rotation). By filtering face stimuli for orientation ... -
Increased Visual Stimulation Systematically Decreases Activity in Lateral Intermediate Cortex
Nasr, Shahin; Stemmann, Heiko; Vanduffel, Wim; Tootell, Roger B. H. (Oxford University Press, 2014)Previous studies have attributed multiple diverse roles to the posterior superior temporal cortex (STC), both visually driven and cognitive, including part of the default mode network (DMN). Here, we demonstrate a unifying ... -
Multimodal analysis of cortical chemoarchitecture and macroscale fMRI resting‐state functional connectivity
van den Heuvel, Martijn P.; Scholtens, Lianne H.; Turk, Elise; Mantini, Dante; Vanduffel, Wim; Feldman Barrett, Lisa (John Wiley and Sons Inc., 2016)Abstract The cerebral cortex is well known to display a large variation in excitatory and inhibitory chemoarchitecture, but the effect of this variation on global scale functional neural communication and synchronization ... -
Neurovascular coupling to D2/D3 dopamine receptor occupancy using simultaneous PET/functional MRI
Sander, C. Y.; Hooker, Jacob M; Catana, Ciprian; Normandin, Marc D; Alpert, Nathaniel Moritz; Knudsen, G. M.; Vanduffel, Wim J.M.; Rosen, Bruce; Mandeville, Joseph B. (Proceedings of the National Academy of Sciences, 2013)This study employed simultaneous neuroimaging with positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) to demonstrate the relationship between changes in receptor occupancy measured by PET ... -
Posterior Parietal Cortex Drives Inferotemporal Activations During Three-Dimensional Object Vision
Van Dromme, Ilse C.; Premereur, Elsie; Verhoef, Bram-Ernst; Vanduffel, Wim; Janssen, Peter (Public Library of Science, 2016)The primate visual system consists of a ventral stream, specialized for object recognition, and a dorsal visual stream, which is crucial for spatial vision and actions. However, little is known about the interactions and ... -
A practical application of text mining to literature on cognitive rehabilitation and enhancement through neurostimulation
Balan, Puiu F.; Gerits, Annelies; Vanduffel, Wim (Frontiers Media S.A., 2014)The exponential growth in publications represents a major challenge for researchers. Many scientific domains, including neuroscience, are not yet fully engaged in exploiting large bodies of publications. In this paper, we ... -
A Receptor-Based Model for Dopamine-Induced fMRI Signal
Mandeville, Joseph B.; Sander, Christin Y.M.; Jenkins, Bruce Gorton; Hooker, Jacob M; Catana, Ciprian; Vanduffel, Wim J.M.; Alpert, Nathaniel Moritz; Rosen, Bruce; Normandin, Marc D (Elsevier BV, 2013)This report describes a multi-receptor physiological model of the fMRI temporal response and signal magnitude evoked by drugs that elevate synaptic dopamine in basal ganglia. The model is formulated as a summation of ...
