Prototype neuroprosthetic enables wireless recording of 2,000 neurons across multiple cortical areas

This manuscript describes a novel approach that integrates state-of-the-art microelectrode cubes that can record, for the first time in the literature, from volumes of cortical tissue, a large scale wireless transmission system for over-the-air transmission of these signals, and the … Continue reading

Long-Term Spinal Cord Stimulation Stalls Parkinson’s Symptoms

Researchers at Duke Medicine have shown that continuing spinal cord stimulation appears to produce improvements in symptoms of Parkinson’s disease, and may protect critical neurons from injury or deterioration. The study, performed in rats, is published online Jan. 23, 2014 … Continue reading

Monkeys Use Minds to Move Two Virtual Arms

In a study led by the Nicolelis Lab, monkeys have learned to control the movement of both arms on an avatar using just their brain activity. The findings, published on Nov. 6, 2013, in the journal Science Translational Medicine, advance efforts … Continue reading

TOUCH AND MOVEMENT NEURONS SHAPE THE BRAIN’S INTERNAL IMAGE OF THE BODY

The brain representation of the body, called the body schema, is susceptible to plasticity. For instance, subjects experiencing a rubber hand illusion develop a sense of ownership of a mannequin hand when they view it being touched while tactile stimuli … Continue reading

FIRST BRAIN-TO-BRAIN INTERFACE ALLOWS TRANSMISSION OF TACTILE AND MOTOR INFORMATION BETWEEN RATS

A brain-to-brain interface (BTBI) enabled a real-time transfer of behaviorally meaningful sensorimotor information between the brains of two rats. In this BTBI, an ‘‘encoder’’ rat performed sensorimotor tasks that required it to select from two choices of tactile or visual … Continue reading

Simultaneous Top-down Modulation of the Primary Somatosensory Cortex and Thalamic Nuclei during Active Tactile Discrimination

The rat somatosensory system contains multiple thalamocortical loops (TCLs) that altogether process, in fundamentally different ways, tactile stimuli delivered passively or actively sampled. To elucidate potential top-down mechanisms that governTCLprocessing in awake, behaving animals, we simultaneously recorded neuronal ensemble activity … Continue reading

Neuroprosthesis Gives Rats the Ability to “Touch” Infrared Light

Sensory neuroprostheses show great potential for alleviating major sensory deficits. It is not known, however, whether such devices can augment the subject’s normal perceptual range. Here we show that adult rats can learn to perceive otherwise invisible infrared light through … Continue reading
