Humans and animal species can move in controlled motion sequences because of a delicate balance in the signaling of certain neurons in the area of the brain called the striatum. In this brain region, some neurons tell muscles to move, while others tell muscles to hold steady. In the brains of patients with Parkinson’s disease, more of the neurons that signal movement are activated resulting...

Journeying along axons, microscopic powerhouses known as mitochondria provide cells with the energy they need to function. When something goes wrong with the axonal transport and mitochondria isn't delivered, the system fails, and the cell body dies. Scientists in the Department of Anatomy and Neurobiology at the Washington University School of Medicine in St. Louis study the cellular bases of neurological disorders. Their recent research focuses...

Patients suffering from Parkinson's disease may have a new way to manage their illness: gene therapy. Scientists at seven leading gene therapy centers across the US saw improvements in patients when a gene that helps produce the inhibitory transmitter GABA was introduced to quiet the subthalamic nucleus, an overactive region of the brain in Parkinson's patients. Twenty-two subjects from a group of 45 patients aged 30-75...

Optogenetics is a fairly new scientific field that combines optical stimulation with genetic engineering. According to a recent article in Wired magazine, neuroscientist, psychologist, and MBF Bioscience customer Dr. Karl Deisseroth and his team of researchers at Stanford University are making major optogenetic advancements - the kind that might lead to a cure for Parkinson's Disease. It all began in 1979, when one of the discoverers...
