Enzyme activity, representing the sites of K+-stimulated p-nitrophenylphosphatase, a component of the sodium, potassium-stimulated-adenosinetriphosphatase system, has been localized in the somatosensory cortex of the rat brain. The reaction product is most obviously associated with fibers that are thought to be axons and dendrites. Large dendrite-like fibers appear to arise in layer 5 of the cortex and arborize in layers 1 through 4. Smaller, reactive fibers are found throughout the cortical layers. Neuron cell bodies did not exhibit substantial enzymatic activity. It did not appear that glia contributed significantly to the activity in cerebral cortex.
代表钾离子刺激的对硝基苯磷酸酶（钠钾刺激的三磷酸腺苷酶系统的一个组成部分）位点的酶活性，已定位在大鼠脑体感皮层中。反应产物最明显地与被认为是轴突和树突的纤维相关。大的树突样纤维似乎起源于皮层第5层，并在第1至4层形成分支。较小的反应性纤维见于整个皮层各层。神经元细胞体未表现出明显的酶活性。似乎神经胶质对大脑皮层的活性没有显著贡献。
