Get real: Orbitofrontal cortex mediates the ability to sense reality in early adolescents

Dimitri Nestor Alice Van De Ville, Roberto Martuzzi, Vanessa Siffredi

Introduction Orbitofrontal reality filtering (ORFi) is a memory mechanism that distinguishes whether a thought is relevant to present reality or not. In adults, it is mediated by the orbitofrontal cortex (OFC). This region is still not fully developed in p ...

Functional imaging of rostrocaudal spinal activity during upper limb motor tasks

Dimitri Nestor Alice Van De Ville, Silvestro Micera, Elvira Pirondini, Nawal Noëlle Kinany, Roberto Martuzzi

The spinal cord is the main interface between the brain and the periphery. It notably plays a central role in motor control, as spinal motoneurons activate skeletal muscles involved in voluntary movements. Yet, the spinal mechanisms underlying human moveme ...

Bilateral Rolandic operculum processing underlying heartbeat awareness reflects changes in bodily self-consciousness

Olaf Blanke, Bruno Herbelin, Andrea Serino, Roy Salomon, Roberto Martuzzi, Javier Bello Ruiz, Maria Laura Blefari

Exteroceptive bodily signals (including tactile, proprioceptive and visual signals) are important information contributing to self-consciousness. Moreover, prominent theories proposed that visceral signals about internal bodily states are equally or even m ...

Upper limb cortical maps in amputees with targeted muscle and sensory reinnervation

Olaf Blanke, Andrea Serino, Michel Akselrod, Wietske Van der Zwaag, Roy Salomon, Giulio Rognini, Roberto Martuzzi, Elisa Canzoneri, Maria Laura Blefari

Neuroprosthetics research in amputee patients aims at developing new prostheses that move and feel like real limbs. Targeted muscle and sensory reinnervation (TMSR) is such an approach and consists of rerouting motor and sensory nerves from the residual li ...

Anatomical and functional properties of the foot and leg representation in areas 3b, 1 and 2 of primary somatosensory cortex in humans: A 7T fMRI study

Olaf Blanke, Andrea Serino, Michel Akselrod, Wietske Van der Zwaag, Roger Gassert, Roberto Martuzzi

Primary somatosensory cortex (S1) processes somatosensory information and is composed of multiple subregions. In particular, tactile information from the skin is encoded in three subregions, namely Brodmann areas (BAs) 3b, 1 and 2, with each area represent ...

The multisensory function of the human primary visual cortex

Roberto Martuzzi, Antonia Thelen

It has been nearly 10 years since Ghazanfar and Schroeder (2006) proposed that the neocortex is essentially multisensory in nature. However, it is only recently that sufficient and hard evidence that supports this proposal has accrued. We review evidence t ...

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 ...

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 ...

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 ...
