Human Brain Mapping, Volume 45, Issue 18, December 15, 2024.Functional imaging of the somatosensory cortex in people with spinal cord injury enabled planning for precise electrode array placement in the brain for a brain–computer interface. Stimulation through electrodes in the somatosensory cortex generated sensations of touch in digits that matched the functional imaging results used for placement.

Optogenetic Brain Interfaces [PDF]
, 2013 The brain is a large network of interconnected neurons where each cell functions as a nonlinear processing element. Unraveling the mysteries of information processing in the complex networks of the brain requires versatile neurostimulation and imaging ...

Rat whisker motor cortex is subdivided into sensory-input and motor-output areas
Frontiers in Neural Circuits, 2013 Rodent whisking is an exploratory behavior that can be modified by sensory feedback. Consistent with this, many whisker-sensitive cortical regions project to agranular motor (MI) cortex, but the relative topography of these afferent projections has not ...

Subtype-specific plasticity of inhibitory circuits in motor cortex during motor learning. [PDF]
, 2015 Motor skill learning induces long-lasting reorganization of dendritic spines, principal sites of excitatory synapses, in the motor cortex. However, mechanisms that regulate these excitatory synaptic changes remain poorly understood.

A shared neural network for emotional expression and perception: An anatomical study in the macaque monkey [PDF]
, 2015 Over the past two decades, the insula has been described as the sensory interoceptive cortex. As a consequence, human brain imaging studies have focused on its role in the sensory perception of emotions.

Epilepsia Open, Volume 9, Issue 6, Page 2518-2521, December 2024.Abstract Hybrid depth electrodes are increasingly being used for epilepsy monitoring and human neurophysiology research. Microwires extending from the tip of the Behnke‐Fried (BF) electrode into (sub)cortical areas allow to isolate single neurons and perform microstimulation.

Restoring tactile and proprioceptive sensation through a brain interface
Neurobiology of Disease, 2015 Somatosensation plays a critical role in the dexterous manipulation of objects, in emotional communication, and in the embodiment of our limbs. For upper-limb neuroprostheses to be adopted by prospective users, prosthetic limbs will thus need to provide ...

FEF inactivation with improved optogenetic methods [PDF]
, 2016 Optogenetic methods have been highly effective for suppressing neural activity and modulating behavior in rodents, but effects have been much smaller in primates, which have much larger brains. Here, we present a suite of technologies to use optogenetics

Intracortical Microstimulation Parameters Dictate the Amplitude and Latency of Evoked Responses
Brain Stimulation, 2016 Microstimulation of brain tissue plays a key role in a variety of sensory prosthetics, clinical therapies and research applications. However, the effects of stimulation parameters on the responses they evoke remain widely unknown.We aimed to investigate the contribution of each stimulation parameter to the response and identify interactions existing ...
