A study co-led by Columbia scientists suggests a nutrient transporter located at the blood-brain barrier could be commandeered to sneak therapeutic drugs into the brain.
Mice lacking an olfactory system have had their sense of smell restored with rat neurons, the first time scientists have successfully integrated the sensory apparatus of one species into another.
An analysis of more than 40,000 primary sensory neurons in the skin has found multiple different types, each sensing a more complex range of stimuli than previously assumed.
Researchers have identified two types of neurons that enable the spinal cord to control skilled forelimb movement. The findings could lead to new ways to treat movement disorders.
Neurologist Scott A. Small participated in a Kavli Foundation roundtable on the link between the brain's ability to make new cells and age-related memory loss.
Using stem cells from patients, P&S researchers have created a model of age-related macular degeneration in a dish, which may lead personalized treatments to prevent vision loss.
