This project endeavored to create an educational module including methodology to instruct physical medicine and rehabilitation residents in the evaluation and appropriate treatment of patients with neuromuscular disorders. It further sought to verify acquired competencies in neuromuscular rehabilitation through objective evaluation methodology. An American Association of Neuromuscular and Electrodiagnostic Medicine board-certified physician with 10 yrs of clinical experience in neuromuscular and general rehabilitation trained 19 residents using a standardized competency-based module.

GAL transgenic (GAL-tg) mice overexpressing endogenous GAL show deficits on the probe trial of the Morris water maze spatial learning task, on the social transmission of food preference olfactory memory task, and on the trace cued fear conditioning emotional learning and memory task. Knockout mice deficient in the GAL-R1 receptor subtype were normal on most memory tasks, while showing a small deficit in trace cued fear conditioning, suggesting a selective role for the GAL-R1 in aversive memories, and implicating other GAL receptor subtypes in spatial learning and olfactory social memory.

Three G-protein-coupled galanin receptor subtypes, designated GAL-R1, GAL-R2 and GAL-R3, have been cloned. The present study examined the role of GAL-R1 in cognition by testing mice with a null mutation in Galr1 on several different types of learning and memory tasks.

Previous findings suggested that galanin modulates anxiety-related behaviors in rodents. Three galanin receptor subtypes have been cloned; however, understanding their functions has been limited by the lack of galanin receptor subtype-selective ligands.
