A comparison of neural and psychophysical responses in the somesthetic system

"Neural and subjective responses to electrical stimulation of the ulnar nerve in the arm were measured as a function of the interval between two successive stimuli . . .. Both were found to increase monotonically as the interpulse interval increased. The results suggest that subjective intensity in this modality is a simple additive function of the amplitude of the neural response within the range of interpulse intervals studied here. Measures of the conduction velocity of the nerve impulse suggest that A fibers are primarily responsible for the observed phenomena." From Psyc Abstracts 36:02.
