in cats , extracellular micro-electrode recordings were made from axons of the spinocervical tract ( s.c.t . ) in both the decerebrate state and during cold block of the spinal cord ( reversible spinal state ) to examine the effects of intra-arterial injection of algesic agents ( bradykinin , potassium , 5-hydroxytryptamine ) into the gastrocnemius-soleus ( g.s . ) muscle on the discharge behaviour of s.c.t . neurones.2 .
