[Changes in the neuronal activity in the dorsolateral pontine region caused by electrical stimulation of the brainstem regions inhibiting movement and the muscle tone].
Activity of 44 mesencephalic locomotor area's (MLR) units and 38 pontine inhibitory area's (PIA) units was recorded during stimulation of the giganto-cellular reticular nucleus and oral pontine reticular nucleus inducing the hindlimb muscle tone inhibition in decerebrated rats. The muscle tone suppression was always accompanied by a decrease in the MLR and an increase in the PIA unit discharges. Stimulation of the brainstem inhibitory area seems to activate reticulospinal inhibitory system and suppress some MLR units relating to locomotion and muscle tone.
