Figure 7. Camera lucida drawings showing projected locations and morphologies of temperature-insensitive neurones (left side) and warm-sensitive neurones (right side) recorded in coronal tissue slices.

Neurones identified at different rostral-caudal locations are projected onto a single coronal plane. Dorsal is at the top. Cells marked with asterisks had dendrites shorter than 200 μm and were not included in the averages shown in Fig. 9 (see Methods).
