Non-invasive brain stimulation in neurological diseases

Non-invasive brain stimulation has shown its potential to modulate brain plasticity in humans. Endeavour has been made to utilize brain stimulation in neurological diseases to enhance adaptive processes and prevent potential maladaptive ones. In stroke for ...

Selective Enhancement of Motor Imagery Features Using Transcranial Direct Current Stimulation

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Robert Leeb, Andrea Biasiucci

Transcranial Direct Current Stimulation (tDCS) has been shown to selectively modulate cortical responses in memory, motor and perceptual tasks. Here we show that this type of stimulation results in targeted enhancement of brain patterns elicited during mot ...

Analysis of fractal electrodes for efficient neural stimulation

Laleh Golestanirad

Planar electrodes are increasingly used in therapeutic neural stimulation techniques such as functional electrical stimulation, epidural spinal cord stimulation and cortical stimulation. Recently, optimized electrode geometries have been shown to increase ...

Investigating Ocular Movements and Vestibular Evoked Potentials for a Vestibular Neuroprosthesis: Response to Pulse Trains and Baseline Stimulation

Silvestro Micera, Thuy Anh Khoa Nguyen

No adequate treatment currently exists for bilateral vestibulopathy, which can result in significant decreases of social and physical functioning. To improve patients' quality of life, vestibular neuroprostheses are being developed. Efficacy of current pro ...

Long-lasting visual integration of form, motion, and color as revealed by visual masking

Michael Herzog

When two similar visual stimuli are presented in rapid succession at the same location, they fuse. For example, a red and a green disk are perceived as one single yellow disk. Likewise, verniers with opposite offset directions are perceived as one vernier ...

Freeing the visual channel by exploiting vibrotactile BCI feedback

José del Rocio Millán Ruiz, Robert Leeb

Controlling a brain-actuated device requires the participant to look at and to split his attention between the interaction of the device with its environment and the status information of the Brain-Computer Interface (BCI). Such parallel visual tasks are p ...

A polymer-based interface restores light sensitivity in rat blind retinas

Diego Ghezzi

Purpose: Sight restoration is one of the new frontiers for prosthetic devices that enable the electrical stimulation of neurons. In particular, diseases that affect the retinal pigment epithelium and photoreceptors but preserve the inner retinal layers are ...

Ultrafast Ca2+ wave in cultured vascular smooth muscle cells aligned on a micropatterned surface

Jean-Jacques Meister, Jean-Louis Bény, Benoît Vianay, Jairo Camilo Quijano Perez

Communication between vascular smooth muscle cells (SMCs) allows control of their contraction and so regulation of blood flow. The contractile state of SMCs is regulated by cytosolic Ca2+ concentration (Ca2+) which propagates as Ca2+ waves over a sign ...

Feel the BCI vibe – vibrotactile BCI feedback

José del Rocio Millán Ruiz, Robert Leeb

Controlling a device via a brain-computer interface (BCI) requires the participant to look and to split the attention between the device and the BCI feedback, which is partly contradictory. Therefore, a stimulation system based on 6 coin-motors is develope ...

Motor Recovery After Stroke by Means of BCI-Guided Functional Electrical Stimulation

José del Rocio Millán Ruiz, Robert Leeb, Andrea Biasiucci

Brain-Computer Interfaces (BCIs) provide a mean to access the damaged motor network of the brain after stroke, and could be used to drive and promote beneficial plasticity. Among the available therapeutic approaches, Functional Electrical Stimulation (FES) ...
