The cause is unclear, but the contractions may involve abnormalities in neural communication. (scientificamerican.com)
Xu hopes these insights into how difficult it is for the brain to amend its plans — a task that only gets harder as we age and neural communication slows — can eventually help researchers devise ways to intervene and help us make faster, safer decisions. (scientificamerican.com)
This prevents the release of neurotransmitters, cutting off neural communication between muscles and the brain. (newscientist.com)
