Subtle changes in fractal motor activity regulation in cognitively healthy women may be a sign of preclinical Alzheimer's disease, researchers report.
For Parkinson's patients, golf is better than tai chi at improving movement and balance.
A new study challenges the popular theory of intrinsic, dynamic patterns control motor behaviors. Researchers found neuron population dynamics in the motor cortex are different during reaching and grasping behaviors.
The brain processes motor commands, not just through fine muscle contractions, but also via higher-level motor areas that provide a blueprint for performing more complex motor functions, such as grasping, no matter if the toes or fingers are used.
Researchers induced arm movements in macaque monkeys by using optogenetics to target the motor cortex.
Neural networks that are directly responsible for the coordination of walking movements are located in the spinal cord. A specific group of neurons in the brainstem signal to the spinal cord and control direction.
Using robotics, researchers uncover mechanisms in the cerebellum and spinal cord that determine how the nervous system responds to induced changes in step length. The findings could have implications for physical rehabilitation programs for people with movement disorders.
