Controlled Release of Bone Morphogenetic Protein-2 Improves Motor Function After Traumatic Brain Injury in a Rat Model Open
Severe traumatic brain injury (TBI) is a life-threatening condition characterized by internal brain swelling and commonly treated using a two-stage surgical approach. The interval between surgeries, generally spaced weeks to months, is ass…

Photoacoustic imaging of squirrel monkey cortical responses induced by peripheral mechanical stimulation Open
Non‐human primates (NHPs) are crucial models for studies of neuronal activity. Emerging photoacoustic imaging modalities offer excellent tools for studying NHP brains with high sensitivity and high spatial resolution. In this research, a p…

Corticocortical connections of the rostral forelimb area in rats: a quantitative tract-tracing study Open
The rostral forelimb area (RFA) in the rat is a premotor cortical region based on its dense efferent projections to primary motor cortex. This study describes corticocortical connections of RFA and the relative strength of connections with…

Spared Premotor Areas Undergo Rapid Nonlinear Changes in Functional Organization Following a Focal Ischemic Infarct in Primary Motor Cortex of Squirrel Monkeys Open
Recovery of motor function after stroke is accompanied by reorganization of movement representations in spared cortical motor regions. It is widely assumed that map reorganization parallels recovery, suggesting a causal relationship. We ex…

Reorganization of Ventral Premotor Cortex After Ischemic Brain Injury: Effects of Forced Use Open
Background Physical use of the affected upper extremity can have a beneficial effect on motor recovery in people after stroke. Few studies have examined neurological mechanisms underlying the effects of forced use in non-human primates. In…

Stimulation-Evoked Effective Connectivity (SEEC): An in-vivo approach for defining mesoscale corticocortical connectivity Open
Background Cortical electrical stimulation has been a versatile technique for examining the structure and function of cortical regions as well as for implementing novel therapies. While electrical stimulation has been used to examine the l…

Anatomical Plasticity of the Distal Forelimb Projection of the Ventral Premotor Cortex Four weeks After Primary Motor Cortex Injury Open
Brain injury affecting the isocortical frontal cortex is a common pathological occurrence. Many patients report severe deficits to functions of daily living. However, there is a variable degree of motor recovery that occurs with some indiv…

Functional Suppression of Premotor Activity in a Transient Model of Motor Cortex Injury Open
Cortical injuries (e.g. – strokes or traumatic brain injuries) can create a host of secondary events that further impair the brain’s sensory, motor, or cognitive capabilities. Here, we attempted to isolate the acute effects of the primary …

Task Related Neural Activity Following Primary Motor Cortical Ischemic Injury in Rats Open
Acquired injuries to primary motor cortex (M1) contribute to motor impairment and disability. Functional recovery is predicated on the reorganization of spared areas, which has been demonstrated through cortical motor map representations a…

Corticocortical Connections of the Rostral Forelimb Area in Rats: A Quantitative Tract-Tracing Study Open
The rostral forelimb area (RFA) in the rat is considered to be a premotor cortical region based primarily on its efferent projections to the primary motor cortex. The purpose of the present study was to identify corticocortical connections…

A miniaturized brain-machine-spinal cord interface (BMSI) for closed-loop intraspinal microstimulation Open
This paper reports on a fully miniaturized brain-machine-spinal cord interface (BMSI) for closed-loop cortical control of intraspinal microstimulation (ISMS). The system incorporates two identical 4-channel modules, with each module compri…

Reversibility of Murine Motor Deficits Following Hemi-Craniectomy and Cranioplasty Open
Motor deficits that are attributed to hemi-craniectomy bone defects alone are demonstrated in a mouse animal model. These motor deficits resemble some symptoms associated with human syndrome of the trephined.

Effects of Subdural Monopolar Cortical Stimulation Paired With Rehabilitative Training on Behavioral and Neurophysiological Recovery After Cortical Ischemic Stroke in Adult Squirrel Monkeys Open
Background. Cortical stimulation (CS) combined with rehabilitative training (RT) has proven effective for enhancing poststroke functional recovery in rats, but human clinical trials have had mixed outcomes. Objective. To assess the efficac…

Output Properties of the Cortical Hindlimb Motor Area in Spinal Cord-Injured Rats Open
The purpose of this study was to examine neuronal activity levels in the hindlimb area of motor cortex following spinal cord injury (SCI) in rats and compare the results with measurements in normal rats. Fifteen male Fischer-344 rats recei…
