Ventral Premotor-Motor Cortex Interactions in the Macaque Monkey during Grasp: Response of Single Neurons to Intracortical Microstimulation [PDF]
Recent stimulation studies in monkeys and humans have shown strong interactions between ventral premotor cortex (area F5) and the hand area of primary motor cortex (M1).

Mapping quantal touch using 7 Tesla functional magnetic resonance imaging and single-unit intraneural microstimulation. [PDF]
Using ultra-high field 7 Tesla (7T) functional magnetic resonance imaging (fMRI), we map the cortical and perceptual responses elicited by intraneural microstimulation (INMS) of single mechanoreceptive afferent units in the median nerve, in humans ...

Estimation of electrode location in a rat motor cortex by laminar analysis of electrophysiology and intracortical electrical stimulation [PDF]
While the development of microelectrode arrays has enabled access to disparate regions of a cortex for neurorehabilitation, neuroprosthetic and basic neuroscience research, accurate interpretation of the signals and manipulation of the cortical neurons ...

Behavioral assessment of sensitivity to intracortical microstimulation of primate somatosensory cortex. [PDF]
Significance Electrical stimulation of sensory structures in the brain is a powerful tool to investigate neural circuits and may provide a means to restore sensation for patients for whom stimulation of the nerve is not an option. For both purposes, however, it is critical to understand how the design of the stimulation shapes the evoked ...

A robot hand testbed designed for enhancing embodiment and functional neurorehabilitation of body schema in subjects with upper limb impairment or loss. [PDF]
Many upper limb amputees experience an incessant, post-amputation "phantom limb pain" and report that their missing limbs feel paralyzed in an uncomfortable posture.

Post-ischemic reorganization of sensory responses in cerebral cortex
IntroductionSensorimotor integration is critical for generating skilled, volitional movements. While stroke tends to impact motor function, there are also often associated sensory deficits that contribute to overall behavioral deficits.

Frontal eye field, where art thou? Anatomy, function, and non-invasive manipulation of frontal regions involved in eye movements and associated cognitive operations [PDF]
The planning, control and execution of eye movements in 3D space relies on a distributed system of cortical and subcortical brain regions. Within this network, the Eye Fields have been described in animals as cortical regions in which electrical ...

Cortical Response to Acute Implantation of the Utah Optrode Array in Macaque Cortex
Delivering light deep into the brain over a large volume while causing minimal tissue damage is a major challenge for non‐human primate optogenetics. This study evaluates Utah Optrode Array designs in vivo, revealing how changes in shank geometry, surface texture, and insertion parameters minimize acute damage—offering a path toward high‐precision ...
