A new in-home device that monitors movement and gait speed can evaluate Parkinson's disease severity, progression, and a patient's response to medication.
A new study sheds light on why humans often use hand movements while talking. Researchers report rhythmic hand gestures affect rib cage movements, leading to a change in lung volume and ultimately aspects of the voice. Infants connect early vocal babbling with hand gestures, demonstrating an early connection between movement and vocal production.
Data collected from a tetraplegic man learning a BCI to play Simon showed the brain replays the learned information during sleep.
Focusing on the largest pyramidal neurons in the motor cortex, researchers found dendritic branches do not simply pass movement information forward. Each sub-branch calculates the information and passes it to larger sub-branches, which in turn, perform the same operation. Multiple dendritic branchlets can interact with each other to amplify their combined computational product.
Latinos aged 55 and older who participated in Latin dance classes for eight months showed significant improvement in working memory over their peers who did not partake in Latin dance.
When learning how to coordinate a new movement, the nervous system first explores and evaluates many different coordinated patterns. With experience, the nervous system then adapts specific aspects of movements and simultaneously decreases pattern variability.
When reaching for a target object, we anchor our gaze to the target of the reach moment, thereby looking at the target for longer periods. This helps make our reach more accurate.
Non-essential amino acids influence the brain in a way that curbs appetite and promotes exercise.
