Altered functional magnetic resonance imaging resting-state connectivity in periaqueductal gray networks in migraine

Objective: The periaqueductal gray matter (PAG), a known modulator of somatic pain transmission, shows evidence of interictal functional and structural abnormalities in migraineurs, which may contribute to hyperexcitability along spinal and trigeminal noci ...

The mammalian circadian timing system: synchronization of peripheral clocks

David Michael Suter

Mammalian physiology has to adapt to daily alternating periods during which animals either forage and feed or sleep and fast. The adaptation of physiology to these oscillations is controlled by a circadian timekeeping system, in which a master pacemaker in ...

Electrical source dynamics in three functional localizer paradigms

Michael Herzog, Gijs Plomp

The visual cortex exhibits functional specialization that can be routinely demonstrated using hemodynamic measures like fMRI and PET. To understand the dynamic nature of cortical processes, however, source imaging with a high temporal resolution is necessa ...

Long-range connectivity of mouse primary somatosensory barrel cortex

Bernard Schneider, Carl Petersen, Rachel Aronoff, Céline Matéo, Ferenc Mátyás

The primary somatosensory barrel cortex processes tactile vibrissae information, allowing rodents to actively perceive spatial and textural features of their immediate surroundings. Each whisker on the snout is individually represented in the neocortex by ...

BOLD responses to trigeminal nerve stimulation

Rolf Gruetter, Carl Petersen, Nathalie Just

The current study investigates a new model of barrel cortex activation using stimulation of the infraorbital branch of the trigeminal nerve. A robust and reproducible activation of the rat barrel cortex was obtained following trigeminal nerve stimulation. ...

Frontal and mesial temporal brain areas contribute to early visual evoked responses as revealed by electrical source imaging

Michael Herzog, Gijs Plomp

Distributed EEG source imaging can reveal the electrical activity underlying visual perception in both cortical and deeper sources. How well electrical source imaging localizes functionally specialized visual areas, such as V1 and MT, has so far not been d ...

Supplementary motor area and anterior intraparietal area integrate fine-graded timing and force control during precision grip

Dominique Chapuis, Roger Gassert, Etienne Burdet

We investigated the neuronal processing of the physiologically particularly important precision grip (opposition of index finger and thumb) by the combination of functional magnetic resonance imaging (fMRI) and an MR-compatible haptic interface. Ten health ...

A (fascinating) litmus test for human retino- vs. non-retinotopic processing

Michael Herzog, Thomas Otto, Marco Boi

In human vision, the optics of the eye map neighboring points of the environment onto neighboring photoreceptors in the retina. This retinotopic encoding principle is preserved in the early visual areas. Under normal viewing conditions, due to the motion o ...

Body ownership and embodiment: vestibular and multisensory mechanisms

Olaf Blanke, Christophe Lopez, Pär Halje

Body ownership and embodiment are two fundamental mechanisms of self-consciousness. The present article reviews neurological data about paroxysmal illusions during which body ownership and embodiment are affected differentially: autoscopic phenomena (out-o ...

Thalamic nuclei clustering on High Angular Resolution Diffusion Images

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Leila Cammoun, Azzurra Grassi

Thalamic nuclei can be distinguished by their characteristic fiber orientations, which influence the diffusion. Fiber orientations are relatively aligned within a nucleus due to the fact that the cerebrocortical striations within a nucleus all target the s ...
