概括

这项研究研究了电性反,探索刺激的振幅和频率如何影响人类的感知. 更高的频率增加了刺痛的感觉和减少了脉冲,这表明感官神经元的发射率会影响感知.

科学领域:

生物医学工程生物医学工程
人与计算机的交互
神经科学是一个神经科学.

背景情况:

电性反提供了一种具有成本效益的方法来增强人与环境的互动.
它增强了自然的触觉反,但可能会引起叠加的刺感觉.
了解这种刺痛的感觉对于优化电系统至关重要.

研究的目的:

为了定量和定性地描述人类对电性反的感知.
研究刺激幅度和频率对感知感觉的影响.
为了探索电性反中刺痛感的起源.

主要方法:

进行了两项涉及人类受试者的实验.
建立了感知和不适的门.
试验对象对九种振幅和频率组合的感觉 (压力与刺痛,恒定与脉冲) 进行了评分.

主要成果:

刺激频率增加导致更多的刺痛和压力减少.
增加的频率也导致了更恒定的和更少的脉冲感觉.
感知变化主要取决于频率,而不是振幅.

结论:

电性刺激的频率显著影响感知到的感觉,特别是的质量.
感官神经元发射速率不一致可能解释了刺痛的感觉.
这些发现为完善通过皮肤进行的电刺激用于触觉增强提供了基础.

关键词:

Thermosensation

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
