The morphology of hair follicle afferent fibre collaterals in the spinal cord of the cat

1. The enzyme horseradish peroxidase (HRP) was injected into single axons that innervated hair follicle receptors to study the morphology of their collaterals in the dorsal horn of the cord. The axons were impaled near the dorsal root entrance zone in the lumbosacral spinal cord of anaesthetized cats and HRP injected by passing current through the intra‐axonal micro‐electrode. The morphology was revealed by subsequent histochemistry.
