title: A study of reception with the use of focused ultrasound. I. Effects on the skin and deep receptor structures in man.
abstract: The possibility of use of focused ultrasound (focused beam of high-frequency mechanical waves) for stimulation of nerve structures was investigated. The stimulation of human hand resulted in various sensations: tactile, temperature, pain etc. The corresponding thresholds were determined and characteristic features of ultrasonically induced sensations were studied. The modality of temperature sensation (warmth-cold) was found to depend on the environmental temperature. The character of pain was dependent upon the type of tissue stimulated. Effective factors in ultrasonic stimulation are discussed.
