Loss of Motor Cortical Inputs to the Red Nucleus after CNS Disorders in Nonhuman Primates

The premotor (PM) and primary motor (M1) cortical areas broadcast voluntary motor commands through multiple neuronal pathways, including the corticorubral projection that reaches the red nucleus (RN). However, the respective contribution of M1 and PM to co ...

Metabolite concentration changes associated with positive and negative BOLD responses in the human visual cortex: A functional MRS study at 7 Tesla

Rolf Gruetter, Yohan Boillat, Lijing Xin, Wietske Van der Zwaag

Negative blood oxygenation-level dependent (BOLD) signal observed during task execution in functional magnetic resonance imaging (fMRI) can be caused by different mechanisms, such as a blood-stealing effect or neuronal deactivation. Electrophysiological re ...

Pathway-, layer- and cell-type-specific thalamic input to mouse barrel cortex

Carl Petersen, Berat Semihcan Sermet, Johannes Maria Mayrhofer

Mouse primary somatosensory barrel cortex (wS1) processes whisker sensory information, receiving input from two distinct thalamic nuclei. The first-order ventral posterior medial (VPM) somatosensory thalamic nucleus most densely innervates layer 4 (L4) bar ...

Distinct vestibular effects on early and late somatosensory cortical processing in humans

Olaf Blanke, Fosco Bernasconi, Christian Pfeiffer, Michiel van Elk

In non-human primates several brain areas contain neurons that respond to both vestibular and somatosensory stimulation. In humans, vestibular stimulation activates several somatosensory brain regions and improves tactile perception. However, less is known ...

Vision in clutter : neural correlates of visual crowding

Vitaly Chicherov

Perception of a visual target can strongly deteriorate in the presence of flanking elements (crowding). Crowding is the main limiting factor in reading and a major contributor to poor vision in amblyopia. In crowding, elements appear jumbled and thus are h ...

Neural correlates of visual crowding

Michael Herzog, Gijs Plomp, Vitaly Chicherov

In visual crowding, target discrimination strongly deteriorates when flanking elements are added. We have recently shown that crowding cannot be explained by simple low-level interactions and that grouping is a key component instead. We presented a vernier ...

The Contributions of Sensory Dominance and Attentional Bias to Cross-modal Enhancement of Visual Cortex Excitability

Micah Murray

Approaching or looming sounds (L-sounds) have been shown to selectively increase visual cortex excitability [Romei, V., Murray, M. M., Cappe, C., & Thut, G. Preperceptual and stimulus-selective enhancement of low-level human visual cortex excitability by s ...

Electrophysiological Evidence for Ventral Stream Deficits in Schizophrenia Patients

Michael Herzog, Maya Roinishvili, Gijs Plomp

Schizophrenic patients suffer from many deficits including visual, attentional, and cognitive ones. Visual deficits are of particular interest because they are at the fore-end of information processing and can provide clear examples of interactions between ...

Distinct illusory own-body perceptions caused by damage to posterior insula and extrastriate cortex

Olaf Blanke, Lukas Heydrich

Recent research in cognitive neuroscience using virtual reality, robotic technology and brain imaging has linked self-consciousness to the processing and integration of multisensory bodily signals. This work on bodily self-consciousness has implicated the ...

Age-related changes in visually evoked electrical brain activity

Michael Herzog, Gijs Plomp

Whereas much is known about the degenerative effects of aging on cortical tissue, less is known about how aging affects visually evoked electrical activity, and at what latencies. We compared visual processing in elderly and young controls using a visual m ...
