Effects of chloralose-urethane anesthesia on single-axon reciprocal Ia IPSPs in the cat.
Reciprocal Ia inhibitory postsynaptic potentials (IPSPs) generated by single afferents have been recorded with signal averaging in unanesthetized ischemic-decapitate cats for comparison with measurements previously obtained from preparations anesthetized with a mixture of chloralose and urethane. The results are similar to those which we obtained recently for single-axon recurrent IPSPs. Together, the studies show that chloralose-urethane anesthesia has a depressant effect on two widely studied circuits in the mammalian spinal cord.
