Could There Eventually be a Cure for Huntington’s Disease?
Huntington’s disease, a neuro-degenerative disorder, affects roughly 5-10 out of every 100,000 people. The disease acts by deteriorating many structures in the brain, beginning with the Caudate Nucleus, which is involved in motor control. By the end of their lives, patients are expected to lose about 30% of their brain mass. In the last few […]
Somewhere Over the Brainbow
Because of the brain’s amazing and incomprehensible complexity, there are billions of neurons that connect and network all the major areas of the brain with the small intricate parts as well. So how can we distinguish one of these neurons from the billions of others? Well, within the past five years more advanced techniques have […]
Licking Rat Pups: The Genetics of Nurture
What would happen if humans were like turtles – alone at birth with no mom to guide them back home? We probably would not survive very long before getting attacked and/or eaten by something bigger than us. For many animal species, instinct guides survival. But for humans and other mammal species, nurture as an infant […]
Light-Up Brains
Studying neurological disorders and identifying the brain regions associated with them often involves selective activation and deactivation of neurons. Blue light has been used in the past to activate cells, but recently Stanford University neuroscientists have figured out a way to use different colors of light to inhibit neurons. Their growing area of research, optogenetics, […]
