| German | German Beschreibung der Registriertechnik zur transcutanen Ableitung von Nervenaktionspotentialen aus Hautnerven (Mikroneurographie). Die rezeptiven Felder von Mechanorezeptoren (Typen: SA I, SA II, RA, HF) und von spezifischen Wärme- und Kälterezeptoren werden definierten mechanischen bzw. thermischen Reizen ausgesetzt und die neurale Reizantwort aufgezeichnet. Analyse der Resultate. Real- und Trickaufnahmen. |
| English | English The film begins by showing the topography of the superficial branch of the radical nerve. By means off particular electrophysiological methods the action potenstial of single skin neves can be recorded in conscious human subjects (microneurography). The experimental procedure for recording of the activity of specific mechanoreceptive and thermoreceptive skin afferents is shown andd the corresponding eletronic stimulators for the quantitative mechanical and thermal stimulation of the skin were demonstrated. The rresonse properties of slowly- and rapidly adaopting mechanoreceptors when stimulated by rectangular-, ramp-, ram- and sinusoidal mechanical stimuli were shown by means of original records and animated drawings. Furtchermore, the respones of specific warm and cold receptors when changing the skin temperature were shown. |
