Change in set point in neuromuscular synapses could explain age-related decline in motor function

Scientists from the School of Medicine at The University of Texas Health Science Center at San Antonio have found a clue as to why muscles weaken with age. In a study published in The Journal of Neuroscience, they report the first evidence that "set points" in the nervous system are not inalterably determined during development but instead can be reset with age. They observed a change in set point that resulted in significantly diminished motor function in aging fruit flies."The body has a set point for temperature (98.
