Me, Myself, and I: Neural Activity for Self versus Other across Development

Solange Noémie Jeanne Denervaud, Paola Zanchi

Although adults and children differ in self-vs.-other perception, a developmental perspective on this discriminative ability at the brain level is missing. This study examined neural activation for self-vs.-other in a sample of 39 participants spanning fou ...

Cortical sensory processing across motivational states during goal-directed behavior

Carl Petersen, Matthieu Pierre Auffret, Georgios Foustoukos, Sami El-Boustani, Johannes Maria Mayrhofer, Maëlle Guyoton

Behavioral states can influence performance of goal-directed sensorimotor tasks. Yet, it is unclear how altered neuronal sensory representations in these states relate to task performance and learning. We trained water-restricted mice in a two-whisker disc ...

The structural connectome and motor recovery after stroke: predicting natural recovery

Jean-Philippe Thiran, Friedhelm Christoph Hummel, Gabriel Girard, Takuya Morishita, Elena Beanato, Maximilian Jonas Wessel, Chang-Hyun Park, Philipp Johannes Koch, Philip Egger, Giorgia Giulia Evangelista

Stroke patients vary considerably in terms of outcomes: some patients present ‘natural’ recovery proportional to their initial impairment (fitters), while others do not (non-fitters). Thus, a key challenge in stroke rehabilitation is to identify individual ...

Anatomically and functionally distinct thalamocortical inputs to primary and secondary mouse whisker somatosensory cortices

Carl Petersen, Georgios Foustoukos, Sami El-Boustani, Berat Semihcan Sermet

Subdivisions of mouse whisker somatosensory thalamus project to cortex in a region-specific and layer-specific manner. However, a clear anatomical dissection of these pathways and their functional properties during whisker sensation is lacking. Here, we us ...

First-person body view modulates the neural substrates of episodic memory and autonoetic consciousness: A functional connectivity study

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Bruno Herbelin, Thomas William Arthur Bolton, Nathan Quentin Faivre, Baptiste Gauthier, Robin Mange, Florian Lance, Lucie Bréchet

Episodic memory (EM) is classically conceived as a memory for events, localized in space and time, and characterized by autonoetic consciousness (ANC) allowing to mentally travel back in time and subjectively relive an event. Building on recent evidence th ...

Gray-matter-specific MR imaging improves the detection of epileptogenic zones in focal cortical dysplasia: A new sequence called fluid and white matter suppression (FLAWS)

Tobias Kober, Xin Chen, Thomas Yu, Nan Chen

Objectives: To evaluate the diagnostic value and characteristic features of FCD epileptogenic zones using a novel sequence called fluid and white matter suppression (FLAWS). ...

Common and distinct brain regions processing multisensory bodily signals for peripersonal space and body ownership

Olaf Blanke, Andrea Serino, Petr Grivaz

We take the feeling that our body belongs to us for granted. However, recent research has shown that it is possible to alter the subjective sensation of body ownership (BO) by manipulating multisensory bodily inputs. Several frontal and parietal regions ar ...

Illusory hand ownership in a patient with personal neglect for the upper limb, but no somatoparaphenia

Olaf Blanke, Andrea Serino, Roberta Ronchi, Lukas Heydrich

The symptoms of patients with left personal neglect are characterized by inattention towards contralesional (left) body parts while at the same time explicitly ascertaining ownership for the neglected hemibody. It is currently unknown if personal neglect i ...

From the early steps of whisker formation to its evolutionary disappearance: the (curious) case of Prdm1 and its regulation

Pierluigi Giuseppe Manti

Whiskers (also known as vibrissae) are sensory organs that are thought to have first appeared in Therapsida, a group of synapsids that includes mammals and evolutionary ancestors like the Thrinaxodon(1). They are highly conserved among mammals to the notab ...

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 ...

Cortical Sensorimotor Reverberations

Carl Petersen, Sylvain Crochet

In this issue of Neuron, Manita et al. (2015) report that reciprocal excitatory interactions between higher-order frontal motor cortex and primary sensorimotor cortex might play a key role in hindlimb sensory perception in mice. In this issue of Neuron, Ma ...

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 ...

How to Measure Cortical Folding from MR Images: a Step-by-Step Tutorial to Compute Local Gyrification Index

Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer

Cortical folding (gyrification) is determined during the first months of life, so that adverse events occurring during this period leave traces that will be identifiable at any age. As recently reviewed by Mangin and colleagues2, several methods exist to q ...

Human Primary Auditory Cortex Follows the Shape of Heschl's Gyrus

Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Melissa Saenz, Stephanie Clarke

The primary auditory cortex (PAC) is central to human auditory abilities, yet its location in the brain remains unclear. We measured the two largest tonotopic subfields of PAC (hA1 and hR) using high-resolution functional MRI at 7 T relative to the underly ...

Induction of an illusory shadow person

Olaf Blanke

Stimulation of a site on the brain's left hemisphere prompts the creepy feeling that somebody is close by. The strange sensation that somebody is nearby when no one is actually present has been described by psychiatric and neurological patients, as well as ...
