In decerebrate cats, we found that iontophoretic application of bicuculline, a GABAA receptor antagonist, attenuated the mesencephalic locomotor region-induced suppression of dorsal horn neurons responding to group III afferent input from the hindlimb. Our findings raise the possibility that GABA release onto dorsal horn neurons in the spinal cord may play an important role in the attenuation of the exercise pressor reflex by central command during exercise.
