in anaesthetized and immobilized cats 32.5 % of the intermediolateral sympathetic preganglionic neurones ( b2-spn ) in t3 , t8-9 and l2 spinal segments can be re-excited antidromically by repeated stimuli only at very long interstimulus intervals ( 16 ms and more ) considerably exceeding the refractoriness of the somata and axons of these neurones .
