Neuroscience

Neuroscience is the multidisciplinary study of the nervous system and a rapidly growing area of expertise at OVC. Our biomedical researchers focus on a variety of topics including characterization of pattern formation during normal brain development, the identification and characterization of novel mechanisms of synaptic plasticity, gene expression patterns and signaling pathways activated in aging and Alzheimer's Disease, the characterization of mutant ion channels in disease and the role of sex hormones in brain function. OVC is also home to veterinary neurologists who study comparative epilepsy, electroencephalography, translational genetics of neurologic disease, neuroimaging, 3D medical modelling, neuroncology, CNS inflammatory diseases, and neurosurgical techniques.
