Quantitative activity-induced manganese-dependent MRI for characterizing cortical layers in the primary somatosensory cortex of the rat

Rolf Gruetter, Mario Gaetano Lepore, Nathalie Just, Matthieu Pierre Auffret, Idrees Samim

The ability of Mn2+ to follow Ca2+ pathways upon stimulation transform them into remarkable surrogate markers of neuronal activity using activity-induced manganese-dependent MRI (AIM–MRI). In the present study, a precise follow-up of physiological paramete ...

We present a first-draft digital reconstruction of the microcircuitry of somatosensory cortex of juvenile rat. The reconstruction uses cellular and synaptic organizing principles to algorithmically reconstruct detailed anatomy and physiology from sparse ex ...

Stroking or Buzzing? A Comparison of Somatosensory Touch Stimuli Using 7 Tesla fMRI

Rolf Gruetter, Wietske Van der Zwaag, Roberto Martuzzi

Studying body representations in the brain helps us to understand how we humans relate to our own bodies. The in vivo mapping of the somatosensory cortex, where these representations are found, is greatly facilitated by the high spatial resolution and high ...

Pathway-specific reorganization of projection neurons in somatosensory cortex during learning

Bernard Schneider, Atanas Stankov

In the mammalian brain, sensory cortices exhibit plasticity during task learning, but how this alters information transferred between connected cortical areas remains unknown. We found that divergent subpopulations of cortico-cortical neurons in mouse whis ...

Voxel-based lesion-symptom mapping of stroke lesions underlying somatosensory deficits

Friedhelm Christoph Hummel

The aim of this study was to investigate the relationship between stroke lesion location and the resulting somatosensory deficit. We studied exteroceptive and proprioceptive somatosensory symptoms and stroke lesions in 38 patients with first-ever acute str ...

Distinct contributions of Brodmann areas 1 and 2 to body ownership

Rolf Gruetter, Olaf Blanke, Andrea Serino, Wietske Van der Zwaag, Roberto Martuzzi, Sebastian Dieguez Falcon

Although body ownership – i.e. the feeling that our bodies belong to us – modulates activity within the primary somatosensory cortex (S1), it is still unknown whether this modulation occurs within a somatotopically defined portion of S1. We induced an illu ...

Parallel pathways from motor and somatosensory cortex for controlling whisker movements in mice

Carl Petersen, Varun Sreenivasan

Mice can gather tactile sensory information by actively moving their whiskers to palpate objects in their immediate surroundings. Whisker sensory perception therefore requires integration of sensory and motor information, which occurs prominently in the ne ...

Detection of Optogenetic Stimulation in Somatosensory Cortex by Non-Human Primates - Towards Artificial Tactile Sensation

Fabien Bertrand Paul Wagner, David Allenson Borton

Neuroprosthesis research aims to enable communication between the brain and external assistive devices while restoring lost functionality such as occurs from stroke, spinal cord injury or neurodegenerative diseases. In future closed-loop sensorimotor prost ...

Behaviour-dependent recruitment of long-range projection neurons in somatosensory cortex

Bernard Schneider, Stefano Carta

In the mammalian neocortex, segregated processing streams are thought to be important for forming sensory representations of the environment(1,2), but how local information in primary sensory cortex is transmitted to other distant cortical areas during beh ...

Digit somatotopy in the human cerebellum: A 7T fMRI study

Rolf Gruetter, Olaf Blanke, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Roberto Martuzzi, Remy Kusters

The representation of the human body in the human cerebellum is still relatively unknown, compared to the well-studied homunculus in the primary somatosensory cortex. The investigation of the body representation in the cerebellum and its somatotopic organi ...
