- 人工智能的人工智能
背景情况:
- 诊断神经性面部疼痛亚型依赖于患者的主观症状描述.
- 客观地区分诸如三神经疼痛之类的疾病仍然是一个挑战.
- 神经成像可以提供非侵入性脑部检查,但缺乏针对疼痛亚型的客观诊断工具.
研究的目的:
- 开发和验证人工智能 (AI) 模型,以使用神经成像数据客观区分神经病性面部疼痛亚型.
- 要区分经典的三角神经疼痛 (CTN),三角神经病痛 (TNP) 和健康的对照 (HC).
- 为了确定基于神经成像的生物标志物,表明这些疼痛条件.
主要方法:

Prosopagnosia
210
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Pain
508
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...
