Motor Learning Mechanism on the Neuron Scale
Motor learning neural mechanism cerebellum sensory-motor integration
2015/6/10
Based on existing data, we wish to put forward a biological model of motor system on the neuron scale. Then we indicate its implications in statistics and learning. Specifically, neuron’s firing frequ...
Researchers at MIT and the University of Vienna have created an imaging system that reveals neural activity throughout the brains of living animals. This technique, the first that can generate 3-D mov...
NEW YORK, NY (January 22, 2014) — Columbia University Medical Center (CUMC) researchers have identified a gene, called matrix metalloproteinase-9 (MMP-9), that appears to play a major role in motor ne...
Researchers from Queensland and the USA have made a unique discovery about how the brain computes sensory information.
The University of Queensland’s Queensland Brain Institute (QBI) has welcomed the support of the MND and Me Foundation in its quest to improve the understanding of Motor Neuron Disease (MND).
