Neurons in the cat's area 17 were stained in Golgi-like fashion following injection of horseradish peroxidase into area 18. Such staining allows classification of neurons on the basis of dendritic morphology. The types of neurons found in area 17 are: pyramidal cells in layers 2, 3 and 4ab; spiny stellate cells in the lower part of layer 3, and in layer 4ab; and a few pyramidal and spindle cells in layer 5. The axons of the spiny stellate cells are finer than those of pyramidal cells; they give off collaterals in deeper cortical layers and may bifurcate when entering the white matter. Spiny stellates in area 17 do not project to area 19; after injections are made into area 17, these neurons are found neither in area 18 nor in area 19. The spiny stellate cell with a long axon is thus categorized as a projection neuron which takes part in the pathway from area 17 to ipsilateral and contralateral area 18.
将辣根过氧化物酶注射到猫的18区后，17区的神经元以类似高尔基染色的方式被染色。这种染色能够根据树突形态对神经元进行分类。在17区发现的神经元类型有：2、3和4ab层的锥体细胞；3层下部和4ab层的棘状星形细胞；以及5层中的一些锥体细胞和梭形细胞。棘状星形细胞的轴突比锥体细胞的轴突更细；它们在皮质深层发出侧支，进入白质时可能会分叉。17区的棘状星形细胞不投射到19区；将染料注射到17区后，在18区和19区都找不到这些神经元。因此，具有长轴突的棘状星形细胞被归类为投射神经元，它参与从17区到同侧和对侧18区的神经通路。
