Subtle changes in fractal motor activity regulation in cognitively healthy women may be a sign of preclinical Alzheimer's disease, researchers report.
Researchers have developed a new model that represents the planning of movement from seeing an object to grasping it.
People whose computer mouse drifted toward a safer option on the screen, even when they ultimately decided to select a riskier option, may be more risk avoidant than their choices would indicate.
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.
Much of a sea star's locomotion is determined by local sensory-motor response at the tube feet level as opposed to global sensory-motor commands. It appears the nervous system relies on the physics of the interaction between the body and the environment to control movement. The findings will help with the development of new robotic systems that utilize a decentralized component to learn hierarchically.
Fruit flies exposed to blue light had significantly reduced longevity than those exposed to natural light or kept in darkness. Exposure to blue light for 12 hours a day accelerated aging phenotypes, causing retinal damage, neurodegeneration, and impaired locomotion.
Columbia team harnesses powerful technology to uncover never-before-seen details of the nervous system, demonstrating SCAPE's broad potential to decipher the brain.
Researchers say the 4.5 million-year old fossil shows evidence of greater reliance on bipedalism than previously suggested.
