A contact thermal stimulator for neurobehavioral research on temperature sensation

A thermal stimulation system is described which is suitable for use in psychophysical, behavioral and neurophysiological studies of temperature sensation. Skin temperature over a restricted area can be maintained at temperatures of 30 to 60[deg]C. Heating from this initial temperature can be achieved at rates from 1.0[deg]C to 30[deg]C/second, up to a maximum temperature of 70[deg]C. Stimulus duration can be varied from 1-15 sec. Safety features are employed to avoid accidental burning of subjects. The system can be used during electrophysiological recording with no electronic interference.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24444/1/0000718.pd
