Influence of Mouse Motor Cortex on Vocal Musculature
… the pallial forebrain to the brainstem vocal motor neurons, which facilitate their vocal dexterity. Songbirds have been the standard model of vocal learning, but there are technical limits to our ability to test various hypotheses about the development and evolution of vocal learning circuits. …

A model for command generation in motor cortex
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2001.

Neural correlates of motor performance in primary motor cortex
… the behavior of cells in the primary motor cortex that correlate with movement of the upper limb. The patterns of behavior of cells before, during, and after the application of an external forcefield to the hand of a primate performing a motor reaching task have been described. In …

Distinct Populations of Layer 5B Pyramidal Neurons in the Primary Motor Cortex
<p>The ability of motor cortex to plan, execute, and refine different movements depends on the coordinated activity of many neurons found across its laminar structure. Layer 5b (L5b), a deep cortical layer that drives output signals from the cortex, contains excitatory pyramidal neurons that …

Neural correlates of motor learning/memory in primary motor cortex of macaque monkeys
Thesis (Ph. D.)--Massachusetts Institute of Technology, Whitaker College of Health Sciences and Technology, 1998.

The Acute GABAergic Effects of Mindfulness Meditation in the Motor Cortex of University Students
Background: Previous research demonstrated the cortical silent period (CSP) protocol, a measure of GABAB related cortical inhibition, reliably reflects differences between psychiatric populations and healthy controls. Furthermore, cognitive behaviour therapy (CBT) and mindfulness meditation (MM) …

Face Motor Cortex Neuroplasticity Associated with Alterations in the Oral Environment of the Adult Rat
Neuroplastic changes in motor representations within the primary motor cortex (M1) have been described after peripheral manipulations and implicated in motor learning and adaptation processes. It is unclear whether dental manipulations, which may result in altered oral sensorimotor functions, are …

Interactions Between Medical Prefrontal Cortex, Orbitofrontal Cortex and Motor Cortex in Value-based Decision Making
… how different sub-regions of rodent prefrontal cortex contribute to value-based decision making, by comparing neural signals related to animal’s choice, its outcome, and action value in orbitofrontal cortex (OFC) and medial prefrontal cortex (mPFC) of rats performing a dynamic two-armed bandit …

The Long-Term Teratogenic Effect of Prenatal Alcohol Exposure on the Somatosensory and Motor Cortex of Rats
… on the primary somatosensory (SI) and primary motor cortex (MI). For over 30 years, PAE has been shown to produce a triad of symptoms (growth deficits, craniofacial dysmorphologies and central nervous system disruptions) diagnosed as fetal alcohol syndrome (FAS) in children and adults. Since …

A wide field-of-view multi-area two-photon microscope for simultaneous imaging of sensory and motor cortex in the mouse brain
Sensorimotor processing is essential to the survival of all organisms, as they take in and act on information from their surroundings. Because of the similarities between the cortices of mice and humans, studying sensorimotor processing in mice can tell us more about the same processes in humans. …

The impact of primary motor cortex, spinal cord, and sciatic nerve cooling on spinal reflex activity in the rat: a reversible deactivation study
… parts of the reflex pathway, namely the primary motor cortex, spinal cord, and sciatic nerve, are incompletely known. This study aims to consider each of these to develop a better understanding of how spinal cord reflexes and the relationship between the central and peripheral nervous systems, …

Characterizing Effects of Sphingosine-1-Phosphate Receptor 1 Activation in Subtypes of Central Amygdala Neurons and Effects of Prenatal Methadone Exposure on Motor Cortex Neurons in Mice
… My second goal was to assess the physiology of motor cortex neurons in mice exposed to prenatal methadone. Methadone is a synthetic μ-opioid agonist used for opioid maintenance therapy and chronic pain management. Methadone treatment for opioid use disorder in pregnant women can result in …
