概括

软压力球通过激活特定的大脑区域来提供舒适性并减少不愉快的感觉. 然而,硬压力球会引起不适,并没有减轻压力.

科学领域:

神经科学是一个神经科学.
心理学心理学心理学
身体的感觉 (somatosensation) 是一种体内感觉.

背景情况:

关于愉快触摸的研究主要研究毛发皮肤中的C触觉纤维.
最近的发现显示,无毛皮肤中的C触觉纤维像手掌一样,增加了对手触觉刺激的兴趣.
活跃的触觉感知及其神经相关物,特别是在手中,仍然未被充分探索.

研究的目的:

调查活跃触摸期间愉快感觉的差异.
使用不同硬度的压力球检查与活跃触摸相关的大脑活动.
探索触觉舒适和手中的不适的神经基础.

主要方法:

功能磁共振成像 (fMRI) 测量了40名健康女性的大脑活动.
参与者积极抓住柔软,中等和硬质的压力球,交替休息时间.
对感知硬度和舒适度的主观评分是在9分级别上收集的.

主要成果:

软和中等压力球被认为是舒适的,激活了丘脑和左岛内皮层,同时减少了右岛内皮层的活动.
硬的压力球引起不适,激活岛屿皮层,丘脑和杏仁体,并降低前带皮层活动.
在感知舒适度和特定的大脑激活模式之间观察到明显的相关性.

结论:

软压力球可以通过增强感知舒适度来缓解厌恶刺激.
硬压力球与不适有关,不太可能在减轻压力方面有效.
通过积极触摸和不同的纹理进行触觉刺激,可显著调节感官知觉和相关的神经通路.

关键词:

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.
