Within the human brain, movement is coordinated by a brain region called the striatum, which sends instructions to motor neurons in the brain. Those instructions are conveyed by two pathways, one that ...
Brain-robot interfaces — apparatuses where brain activity controls the movements of a robotic device that supports a hand or limb — show promise in rehabilitating paralyzed stroke patients. Yet the ...
Stroke and spinal cord injuries can severely impair motor functions, and understanding how to promote recovery is a critical challenge. While damaged neurons in the brain and spinal cord have limited ...
A Georgetown University neuroscience professor discussed her research on motor pathways at the Georgetown University Medical Center on Feb. 20. The department of biochemistry hosted the talk on ...
In a recent study published in Nature Neuroscience, a group of researchers explored how the cerebellum directly affects dopamine release in the substantia nigra compacta (SNc). While the cerebellum's ...
When a movement that has already been initiated must be suddenly stopped, a “hyperdirect” subthalamic nucleus pathway is called upon to override the primary motor control systems of the cerebral ...
Your nerves transmit messages within the brain, as well as among the brain, spinal cord, and the body. In order to do this, they use a combination of electrical and chemical signaling. Motor neurons ...
In 2020, as the COVID-19 pandemic escalated, many universities shut down or reduced the capacities of research laboratories in an attempt to limit the spread of the virus. At Washington University ...
New research shows that physical pressure from brain tumors or injuries triggers a "self-destruction" program in neurons, leading to irreversible brain damage.
