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 ...

Muscle synergies and spinal maps are sensitive to the asymmetry induced by a unilateral stroke

Silvestro Micera, Martina Coscia

Background: Previous studies have shown that a cerebrovascular accident disrupts the coordinated control of leg muscles during locomotion inducing asymmetric gait patterns. However, the ability of muscle synergies and spinal maps to reflect the redistribut ...

Structural plasticity of remote cortical brain regions is determined by connectivity to the primary lesion in subcortical stroke

Friedhelm Christoph Hummel

Cortical atrophy as demonstrated by measurement of cortical thickness (CT) is a hallmark of various neurodegenerative diseases. In the wake of an acute ischemic stroke, brain architecture undergoes dynamic changes that can be tracked by structural and func ...

Detection of hyperacusis condition in tinnitus patients based on PLSC features that link audiogram and fMRI tonotopy responses

Dimitri Nestor Alice Van De Ville, Melissa Saenz, Wietske Van der Zwaag, Naghmeh Ghazaleh

Tinnitus is the chronic perception of ringing or other phantom sounds. Some tinnitus patients addi- tionally suffer from loudness hyperacusis that is the over-sensitivity to environmental sounds. Here, we recruited eight patients with unilateral hearing lo ...

Intrahemispheric cortico-cortical connections of the human auditory cortex

Jean-Philippe Thiran, Alessandra Griffa, Reto Meuli, Patric Hagmann, Leila Cammoun, Stephanie Clarke

The human auditory cortex comprises the supratemporal plane and large parts of the temporal and parietal convexities. We have investigated the relevant intrahemispheric cortico-cortical connections using in vivo DSI tractography combined with landmark-base ...

Retinotopy of visual masking and non-retinotopic perception during masking

Michael Herzog

Due to the movements of the observer and those of objects in the environment, retinotopic representations are highly unstable during ecological viewing conditions. The phenomenal stability of our perception suggests that retinotopic representations are tra ...

Whisking-Related Changes in Neuronal Firing and Membrane Potential Dynamics in the Somatosensory Thalamus of Awake Mice

Carl Petersen

The thalamus transmits sensory information to the neocortex and receives neocortical, subcortical, and neuromodulatory inputs. Despite its obvious importance, surprisingly little is known about thalamic function in awake animals. Here, using intracellular ...

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 ...

High-field functional MRI (7 Tesla) mapping of Tonotopy in Human primary auditory cortex in patients with unilateral hearing loss and tinnitus.

Melissa Saenz, Wietske Van der Zwaag, Naghmeh Ghazaleh

Tinnitus, the chronic perception of ringing or other phantom sounds, is typically associated with hearing loss. Recent studies in mouse models have alleviated tinnitus symptom by reversing plastic reorganization observed in the tonotopic maps of primary au ...

Human finger somatotopy in areas 3b, 1, and 2: A 7T fMRI study using a natural stimulus

Rolf Gruetter, Olaf Blanke, Wietske Van der Zwaag, Roberto Martuzzi, Juliane Farthouat

To study the properties of human primary somatosensory (S1) cortex as well as its role in cognitive and social processes, it is necessary to noninvasively localize the cortical representations of the body. Being arguably the most relevant body parts for ta ...
