The rostrocaudal location of sympathetic preganglionic neurones (SPNs) in the intermediolateral cell column of the third thoracic segment was studied in the cat by the retrograde transport of horseradish peroxidase and by recording of antidromic field potentials in the spinal cord in response to stimulation of white ramus T3. By both methods, the position of the rostral and caudal border of SPNs was determined in relation to the entry of segmental dorsal roots. It was found that SPN's are confined in the spinal cord to the length of one segment (9494 +/- 823 micron), but are shifted rostrally by about 3 mm with respect to the point of entry of the dorsal roots of segment T3.
