Camera lucida drawings of CTb-labeled lamina I STT cells in the horizontal plane (medial up and caudalleft) representative of the variety of fusiform cells (F) with their subtypes [(a) regular and (b) irregular], pyramidal (P) cells with their subtypes [(a) longitudinal pyramidal cells, (b) triangular cells with radiating dendrites, and (c) triangular cells with irregular protrusions], and multipolar (M) cells with their subtypes [(a) quadrilateral cells, (b) radiating cells, (c) π- or T-like cells, and (d) tubular cells], and unclassified cells (U).
