Exploring dynamic functional connectivity by incorporating prior knowledge of brain structure

The synchronized firing of distant neuronal populations gives rise to a wide array of functional brain networks that underlie human brain function. Given the enormous perception, learning, and cognition potential of the human brain, it is not surprising th ...

Cortical circuits for transforming whisker sensation into goal-directed licking

Carl Petersen, Sylvain Crochet, Georgios Foustoukos, Vahid Esmaeili, Keita Tamura, Anastasiia Oryshchuk

Animals can learn to use sensory stimuli to generate motor actions in order to obtain rewards. However, the precise neuronal circuits driving learning and execution of a specific goal-directed sensory-to-motor transformation remain to be elucidated. Here, ...

Multisensory haptic system and method

Olaf Blanke, Simon Gallo, Giulio Rognini

A computer-implemented method for operating a haptic device, the haptic device comprising a plurality of tactile displays configured to provide haptic stimuli to a user, the method including the steps of (a) processing an audio signal derived from an audio ...

Imagined paralysis alters somatosensory evoked-potentials

Olaf Blanke, Fred Mast, Christophe Lopez, Estelle Palluel, Silvia Marchesotti

Recent studies employing body illusions have shown that multisensory conflict can alter body representations and modulate low-level sensory processing. One defining feature of these body illusions is that they are sensory driven and thus passive on behalf ...

Towards everyday brain-computer interfacing through decoding visual cognition

Ruslan Aydarkhanov

Decoding visual cognition from non-invasive measurements of brain activity has shown valuable applications. Vision-based Brain-Computer Interfaces (BCI) systems extend from spellers to database search and spatial navigation. Despite the high performance of ...

Crossmodal Congruency Enhances Performance of Healthy Older Adults in Visual-Tactile Pattern Matching

Friedhelm Christoph Hummel

One of the pivotal challenges of aging is to maintain independence in the activities of daily life. In order to adapt to changes in the environment, it is crucial to continuously process and accurately combine simultaneous input from different sensory syst ...

Increased Neural Strength and Reliability to Audiovisual Stimuli at the Boundary of Peripersonal Space

Jean-Paul Noel, Andrea Serino

The actionable space surrounding the body, referred to as peripersonal space (PPS), has been the subject of significant interest of late within the broader framework of embodied cognition. Neurophysiological and neuroimaging studies have shown the represen ...

Optimal integration of intraneural somatosensory feedback with visual information: a single-case study

Silvestro Micera, Ivo Strauss, Giacomo Valle, Francesco Iberite

Providing somatosensory feedback to amputees is a long-standing objective in prosthesis research. Recently, implantable neural interfaces have yielded promising results in this direction. There is now considerable evidence that the nervous system integrate ...

Creating a neuroprosthesis for active tactile exploration of textures

Solaiman Shokur, Miguel Nicolelis

Intracortical microstimulation (ICMS) of the primary somatosensory cortex (S1) can produce percepts that mimic somatic sensation and, thus, has potential as an approach to sensorize prosthetic limbs. However, it is not known whether ICMS could recreate act ...

Characterization of multi-channel intraneural stimulation in transradial amputees

Pablo Garcia del Valle, Edoardo D'Anna, Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle, Fiorenzo Artoni

Although peripheral nerve stimulation using intraneural electrodes has been shown to be an effective and reliable solution to restore sensory feedback after hand loss, there have been no reports on the characterization of multi-channel stimulation. A deepe ...

TacTiles: Dual-Mode Low-Power Electromagnetic Actuators for Rendering Continuous Contact and Spatial Haptic Patterns in VR

Herbert Shea, Juan José Zarate, Ronan Julien Hinchet

We introduce TacTiles, light (1.8g), low-power (130 mV), and small form -factor (1cm(3)) electromagnetic actuators that can form a flexible haptic array to provide localized tactile feedback. Our novel hardware design uses a custom 8 -layer PCB, dampening ...

Sensorimotor processing in the rodent barrel cortex

Carl Petersen

Tactile sensory information from facial whiskers provides nocturnal tunnel-dwelling rodents, including mice and rats, with important spatial and textural information about their immediate surroundings. Whiskers are moved back and forth to scan the environm ...
