A new study suggests that caffeine may alter how the brain responds to touch and body movements.
Researchers investigated how a 200mg dose of caffeine affects short-latency afferent inhibition (SAI), a brain process that filters sensory input for smooth movements.
The study, involving 20 healthy adults, found that caffeine enhanced SAI, increasing the brain’s ability to restrict muscle responses after a touch.
Scientists believe caffeine achieves this by blocking adenosine receptor proteins, leading to an increase in acetylcholine, a chemical messenger vital for sensory and muscle control.
These findings offer insights into caffeine’s physiological actions and its potential relevance to neurological conditions like Alzheimer’s and Parkinson’s disease.
