 Aspiny neurons, the second class of neurons found in the stratum lucidum, are another type of inhibitory cell similar to spiny neurons, though lacking dendrite projections.They make up the majority of the neuron composition in comparison to spiny neurons, about 63 percent.The somata of aspiny neurons are for the most part bipolar, generating 2–5 primary dendrites "that to a varying extent displayed varicose swellings in their course".
