背景情况:
- 每天的上肢活动需要分散注意力,通过双任务干扰 (DTi) 来研究.
- 自身感知对于运动规划和运动控制至关重要.
- 研究DTi对意识上肢自觉感应的影响至关重要.
研究的目的:
- 检查双任务干扰如何影响意识上肢自觉.
- 在认知和运动双重任务条件下,在主动关节重新定位任务期间评估自身感知准确性.
主要方法:
- 42名健康的成年人 (18-35岁) 进行了积极关节重新定位任务 (AJRT).
- 任务在三个条件下进行:基线,双认知 (连续减法) 和双动力 (非主导手动).
- 使用Biodex System III和PRO-Reach测量自身感知错误 (PE),从基线分析干扰变化得分.
主要成果:

01:33Somatosensation
36.9K
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.

01:14Motor and Sensory Areas of the Cortex
8.1K
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

01:28Major Somatic Sensory Pathways
3.2K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...
