The description of painful phenomena in humans has to take into account its different components: sensory component (relevant to nociception), affective and emotional components. Nociceptor's (physiology is best understood with electrophysiological and neurochemical methods allowing a clear description of hyperalgesia, with its peripheral and spinal mechanisms. A functional model is partly available to explain allodynia, spontaneous burning pain and lightning pain, the three main consequences following deafferentation. At the thalamo-cortical level, one can describe nociceptive pathways and other pathways or neuronal networks involved in the affective and emotional components of pain.
感觉成分（与伤害感受相关）、情感和情绪成分。伤害感受器（其生理学通过电生理和神经化学方法能得到最佳理解，这些方法可清晰描述痛觉过敏及其外周和脊髓机制）。目前有一个功能模型可部分解释去传入神经后出现的三种主要后果——异常性疼痛、自发性灼痛和闪电样疼痛。在丘脑 - 皮质水平，可以描述伤害性感受通路以及参与疼痛情感和情绪成分的其他通路或神经网络。
