项目摘要

Kinesthesia, the ability to accurately perceive the position and movement of the body without the aid of vision, is vital for the control of human movement. The study of this remarkable ability has had a long and interesting history. Initially, "corollary" commands from the brain, associated with the descending command to move, were thought to mediate our kinesthetic senses. Subsequently, receptors in joints held favor as the main kinesthetic input signals. Since the 1970's, however, signals from muscle spindles (length sensitive receptors in muscle) have consistently been demonstrated to provide signals that are important for kinesthesia. In more recent years, evidence has accumulated that signals from receptors in the skin also contribute. The prosed research program is designed to determine how signals from multiple sensory modalities work together for kinesthesia. Feedback from cuntaneous receptos, muscle spindles and bvison will be manipulated to determine how the different sources of kinesthetic information are "integrated" to provide our kinesthetic ability. Cutaneous receptors will be activated by stretching the skin to mimic the way that skin stretches during natural movements. Muscle spindles will be activated by exploiting history dependent changes in their discharge (thixotropy), to evoke illusions of altered postion, and vibration will be used to produce illusions of movement. Vision will be manipulated by having participants view their arm in a virtual reality space in which at times the virtual hand accurately reflects their own movements and other times the virtual hand is controlled by the experimenter. The various input signals (cutaneous receptors, muscle spindles, vision, corollary discharge) will be manipulated such that they are either all consistent with a given movement (i.e. flexion or extension) or conflict (i.e. cutaneous and muscle input consistent with flexion, vision and corollary discharge consistent with extension). In some experiments participants will match perceived movements of the (stationary) experimental limb with voluntary movements around the homologous joint on the opposite side of the body. The amplitude of the voluntary "matching'" movements will be used to quantify the amplitude of illusory movements perceived under different conditions. In other experiments, participants will reach or point to virtual targets and the influence of the various input signals will be assessed by errors in trajectories and end points. The results of these experiments will contribute to our understanding of how different sensory modalities are used for kinesthesia.
动觉是一种在没有视觉帮助的情况下准确感知身体位置和运动的能力,对于人体运动的控制至关重要。对这种非凡能力的研究有着悠久而有趣的历史。最初,来自大脑的“必然”命令,与下行命令相关联,被认为是调节我们的动觉感官。随后,关节中的受体作为主要的动觉输入信号而受到青睐。然而,自20世纪70年代以来,来自肌梭(肌肉中的长度敏感受体)的信号一直被证明提供对动觉重要的信号。近年来,越来越多的证据表明,来自皮肤受体的信号也有贡献。该研究计划旨在确定来自多种感觉方式的信号如何共同作用于动觉。从电流感受器,肌梭和bvison的反馈将被操纵,以确定如何不同来源的动觉信息是“整合”,以提供我们的动觉能力。皮肤感受器将通过拉伸皮肤来激活,以模仿皮肤在自然运动期间拉伸的方式。肌梭将通过利用其放电(触变性)中的历史依赖性变化来激活,以唤起位置改变的错觉,振动将用于产生运动的错觉。视觉将通过让参与者在虚拟现实空间中观察他们的手臂来操纵,在虚拟现实空间中,有时虚拟手准确地反映他们自己的动作,而其他时候虚拟手由实验者控制。将操纵各种输入信号(皮肤感受器、肌梭、视觉、必然放电),使得它们全部与给定运动一致(即屈曲或伸展)或冲突(即皮肤和肌肉输入与屈曲一致,视觉和必然放电与伸展一致)。在某些实验中,参与者会将(静止的)实验肢体的感知运动与身体另一侧同源关节周围的自愿运动相匹配。自愿“匹配”运动的幅度将被用来量化在不同条件下感知的错觉运动的幅度。在其他实验中,参与者将到达或指向虚拟目标,各种输入信号的影响将通过轨迹和终点的误差来评估。这些实验的结果将有助于我们理解不同的感觉方式是如何用于动觉。
