疼痛、瘙痒、热、冷和触摸代表了由躯体感觉输入引起的不同感知。刺激是如何引起这些知觉的,这一问题已经争论了世纪。最近的工作支持这样的观点,初级传入是高度专业化的,以刺激和编码特定的刺激方式。然而,跨模式的相互作用(例如,通过触摸抑制或加剧疼痛)支持集中,而不是特异性的中央电路。我们概述了如何周边专业化与中央会聚可以使脊髓微电路联合收割机输入从不同的专业化,共同激活传入和调制输出信号,从而形成通过计算,如归一化。这些问题将被讨论一起在我们的理解在浅背角的微电路的最新进展。
Pain, itch, heat, cold, and touch represent different percepts arising from somatosensory input. How stimuli give rise to these percepts has been debated for over a century. Recent work supports the view that primary afferents are highly specialized to transduce and encode specific stimulus modalities. However, cross-modal interactions (e.g. inhibition or exacerbation of pain by touch) support convergence rather than specificity in central circuits. We outline how peripheral specialization together with central convergence could enable spinal microcircuits to combine inputs from distinctly specialized, co-activated afferents and to modulate the output signals thus formed through computations like normalization. These issues will be discussed alongside recent advances in our understanding of microcircuitry in the superficial dorsal horn.
