1P1-A04 Understanding the Mechanism of Addition of Thermal Sensation to Tactile Stimulation(Tactile and Force Sensing(3))

Abstract

When the heat stimulation is presented to tip of the index finger and the vibratory stimulation is presented to tip of the middle finger, the middle finger is also perceived to be warm. This phenomenon is known as a kind of the thermal illusion called Thermal Referral. To reveal the mechanism of the Thermal Referral, we focused on tactile mechanoreceptors. We varied the frequencies of vibratory stimulation to stimulate different mechanoreceptors, and we evaluate the mechanoreceptors concerned with Thermal Referral.
