Substance P-immunoreactive (SP-IR) neurons are found throughout the layers of the rat neocortex. Within the somatosensory (SI) cortex these cells make up about 2% of all neurons and within area 17 about 3%. Colocalization studies reveal that the SP-IR neurons are a subset of the population immunoreactive for glutamic acid decarboxylase.
在大鼠新皮层的各层中均发现了P物质免疫反应性（SP-IR）神经元。在躯体感觉（SI）皮层中，这些细胞约占所有神经元的2%，在17区约占3%。共定位研究表明，SP-IR神经元是谷氨酸脱羧酶免疫反应性群体的一个子集。
