group iii ( aspiny neurons with thin , tapering dendrites ) consists of small to medium size neurons which can be further divided into two groups : group iiia , which is characterized by oval- to fusiform-shaped neurons with tortuous , fine , tapered dendrites which ramify in the dorsolateral fasciculus and the lateral funiculus , and group iiib , which is composed of fusiform-pyramidal-and polygonal-shaped neurons with fine , tapering dendrites confined to lamina i .
