Active tactile exploration using a brain-machine-brain interface

Hannes Bleuler, Solaiman Shokur, Miguel Nicolelis, Mikhail Lebedev

Brain–machine interfaces1, 2 use neuronal activity recorded from the brain to establish direct communication with external actuators, such as prosthetic arms. It is hoped that brain–machine interfaces can be used to restore the normal sensorimotor function ...

Integration of a virtual reality based arm in primary somatosensory cortex

Hannes Bleuler, Solaiman Shokur, Miguel Nicolelis, Mikhail Lebedev

Abstract: Recent advances in brain-machine interfaces (BMIs) have demonstrated the possibility of motor neuroprosthetics directly controlled by brain activity. Ideally neuroprosthetic limbs should be integrated in the body schema of the subject. To explore ...

Motor control by sensory cortex

Carl Petersen, Varun Sreenivasan, Rachel Aronoff, Céline Matéo, Ferenc Mátyás, Fred Marbach, Catherine Wacongne

Classical studies of mammalian movement control define a prominent role for the primary motor cortex. Investigating the mouse whisker system, we found an additional and equally direct pathway for cortical motor control driven by the primary somatosensory c ...

Long-range connectivity of mouse primary somatosensory barrel cortex

Bernard Schneider, Carl Petersen, Rachel Aronoff, Céline Matéo, Ferenc Mátyás

The primary somatosensory barrel cortex processes tactile vibrissae information, allowing rodents to actively perceive spatial and textural features of their immediate surroundings. Each whisker on the snout is individually represented in the neocortex by ...

Application of Tactile Perception Enhancement

Sylvain Cardin

Surrounding environment is mainly perceived through sight and hearing. Our sense of touch is mostly dedicated to explore the surface of objects using hands and fingers. Tactile sensitivity of the body skin is rather limited in common life, however this rep ...

Properties of neocortical microcircuits

Thomas Berger

The mammalian neocortex is one of the most complex brain areas, integrating all sensory modalities and allowing the animal to perform high level cognitive operations. Despite some cytoarchitectural specializations, the general neocortical structure is rema ...

Designable Visual Markers

Jeffrey Huang, Enrico Costanza

Visual markers are graphic symbols designed to be easily recognised by machines. They are traditionally used to,track goods, but there is increasing interest in their application to mobile HCI. By scanning a visual marker through a camera phone, users can ...

Motor intention in the posterior parietal cortex

Jugoslava Acimovic

The complexity of processes occurring in the brain is an intriguing issue not just for scientists and medical doctors, but the humanity in general. The cortex ability to perceive and analyze an enormous amount of information in an instance of time, the par ...

Pointing with the eyes: The role of gaze in communicating danger

Nouchine Hadjikhani

Facial expression and direction of gaze are two important sources of social information, and what message each conveys may ultimately depend on how the respective information interacts in the eye of the perceiver. Direct gaze signals an interaction with th ...

The functional organization of the barrel cortex

Carl Petersen

The tactile somatosensory pathway from whisker to cortex in rodents provides a well-defined system for exploring the link between molecular mechanisms, synaptic circuits, and behavior. The primary somatosensory cortex has an exquisite somatotopic map where ...
