Subtle changes in fractal motor activity regulation in cognitively healthy women may be a sign of preclinical Alzheimer's disease, researchers report.
Primates with larger brains can solve much more complex tasks using their hands than smaller-brained primates. However, improved dexterity comes at a cost. In humans and other large-brained primates, it takes longer for infants to learn the simplest hand and finger movements than our smaller-brained counterparts.
Researchers combined intact neurons from a rat's spinal cord with a tissue-engineered 3D muscle system, creating a biohybrid robot, or biobot. After culturing the system for seven days, the motor neurons from the spinal cord produced electrical activity, causing contractions in the artificial muscles and mimicking the behavior of the peripheral nervous system. The findings could have positive implications for the treatment of neurodegenerative disorders that affect motor control.
The latest Silicon Valley crazy of dopamine fasting promises to "reset" the brain to be more effective and appreciate the smaller things in life more easily, but does it work? Researchers look at the effect of dopamine fasting on brain health.
A new fruit fly study reveals a simple genetic system is behind complex movements. The finding sheds light on motor control issues associated with neurodegenerative diseases.
Study identifies a population of neurons in an area of the midbrain, called the red nucleus, that alter when fine motor skills are learned. The more an action is practiced, the stronger the connections between these neurons become.
Polydactyly, a condition where one is born with an extra finger, has significant benefits when it comes to motor skill and control. fMRI neuroimaging reveals those with extra fingers are able to move the digits independently of other fingers. The findings could help with the development of new prosthetics that extend motor abilities.
Astrocytes can alter neurons to drive behaviors associated with ADHD. Researchers believe astrocytes may be used to develop targeted treatments for behavioral deficits associated with a range of mental illnesses.
