概括

患有发育协调障碍 (DCD) 的成年人表现出改变的触觉和视听感官处理. 这些感知差异与运动症状相关,这表明DDC在DDC中的作用.

科学领域:

神经科学是一个神经科学.
发展心理学发展心理学
发动机控制器的控制器

背景情况:

发育协调障碍 (DCD) 的特点是运动困难.
假设非典型的感官处理有助于DCD中的运动非典型性.
在DCD中感官变化的域特异性仍然不清楚.

研究的目的:

为了调查DCD成年人的领域特定与全球感官处理变化的研究.
检查患有DCD的个体的触觉感知和视听整合.
探索感官处理,时空融合和DCD症状严重程度之间的关系.

主要方法:

评估了触觉感知,视听集成 (声音诱导的双闪光幻觉) 和时空集成 (Tau-Kappa效应).
在患有DCD (N=16),可能的DCD (pDCD,N=12) 和神经类型成人 (NT,N=28) 的成年人中比较感官处理.
与自我报告的DCD症状严重程度相关的感官处理措施.

主要成果:

与NT成年人相比,在DCD和DCD+pDCD组中观察到触觉感知减少.
视听集成在DCD组中减少,而不是扩展的DCD+pDCD组.
时空整合能力 (Tau-Kappa效应) 在所有组中都完好无损;感官缺陷与DCD症状严重程度相关.

结论:

在DCD中存在低级感官处理 (触觉,视听) 的变化.
在DCD中,感官处理差异是域特定的,而不是全局的.
感知异常可能通过内部建模机制导致DDC的运动困难.

Somatosensation

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
