A tactile stimulator for studying motion processing in the somatic sensory system of primates

A tactile stimulator was built for studying motion processing in the somatic sensory system of primates. This stimulator is used for assessing the responses of neurons of the somatic sensory system to stimuli moving in any traverse distance (range: 2-20 mm), with a variety of velocities (range: 4-120 mm/s), forces (range: 0-60 gf), and in any scanning direction. The stimulator is highly automated and can be used in combined psychophysical and neurophysiological studies in humans and in behaving monkeys.
