In Brief: Writer's cramp is partly in your head - but where?
Writer's cramp is partly in your head — but where?
Writer's cramp is a painful spasm that may afflict anyone who wields a pen. Clearly writer's cramp involves hand muscles, but its brain basis remains unclear.
Previous studies have suggested that the basal ganglia, a part of the brain that plays an important role in motor coordination, might be involved in writer's cramp. But more recent research is implicating the cerebellum, which also helps to control movement by activating a different neural network.
