Analysis of Paradoxical Phenomenon Caused by Presenting Thermal Stimulation on Three Spots
نویسندگان
چکیده
Thermal referral (TR) and thermal grill illusion (TGI), known as illusions of thermal sensation, have been well studied. In a previous study, an experiment using two thermal-tactile stimulations to the forearm revealed that these illusions simultaneously occurred. In this experiment result, a few subjects perceived a hot stimulation as a cold sensation and/or a cold stimulation as a hot sensation. This paradoxical phenomenon of thermal sensation, which is not discussed specifically in the previous study, could be a fatal problem in the case presenting thermal stimulation on multiple spots intentionally. Therefore, we decided to analyze this paradoxical phenomenon. In this paper, we confirmed that this phenomenon occurs when we present thermal stimulation on two spots and three spots. In comparing the results of thermal stimulation on two spots and three spots, the occurred probability increased on three spots.

متن کاملThe role of Na+-K+-ATPase in the basic and rate-dependent properties of isolated perfused rabbit Atrioventricular Node
Introduction: Ouabaine is a well-known atrioventricular (AV) node depressant agent, but its effects on functional properties of the AV node have not been cleared. The aim of the present study was to determine how ouabaine administration modifies the rate-dependent properties of the AV node. Methods: Selective stimulation protocols were used to quantify independently electrophysiological prop...
متن کاملEffects of electrical stimulation of the mesencephalon and diencephalon on the paradoxical phase of sleep.
During paradoxical sleep electrical stimulation of the mesencephalic reticular formation and emotiogenic structures in the mesencephalon and diencephalon produced depression or an increase in the theta rhythm of the hippocampal and entorhinal electrical activity. However, stimulation not involving behavioral arousal did not cause a transition from paradoxical phase into slow wave sleep. The ces...
