概括
社交接触可以缓解疼痛,可能是通过同步的大脑活动. 使用间交流电刺激的个体之间增强阿尔法频段同步可能会增加这种疼痛缓解,特别是对不太有同情心的个体.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 疼痛管理 疼痛管理
背景情况:
- 众所周知,社交接触,特别是作为情感支持,可以缓解疼痛.
- 在体感皮层的α大脑间同步是潜在的神经机制,是触觉诱导疼痛缓解的基础.
- 了解和操纵大脑间的通信可以提供新的疼痛缓解策略.
研究的目的:
- 调查是否人工操纵大脑间通信调节触觉诱导的止痛.
- 探索疼痛感受器和触摸器之间的α频段同步作用,使用跨交替电流刺激 (tACS).
- 检查同理心水平对大脑间同步和疼痛缓解之间的关系的影响.
主要方法:
- 十六对同性参与者被分配为疼痛接受者和触摸给予者的角色.
- 在三种条件下,对体感官皮层进行了阿尔法带tACS的应用:接收者tACS/给予者的假象,两个tACS (超-tACS) 和两个假象.
- 评估了疼痛感知,并分析了与同理心水平的相关性.
主要成果:
- 社交触摸可以减轻疼痛,但在三个tACS条件中没有发现疼痛感知的显著差异.

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

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.

The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...
