Abstract This report concerns a patient with a functionally complete spinal cord transection due to trauma at T-6. Her clinical syndrome of a motor and sensory paraplegia was accompanied by hyperreflexic detrusor dysfunction. Radiofrequency-coupled bilateral stimulation of the 3rd sacral nerves in their intraspinal but extradural course achieved reliable, effective emptying of the bladder. This single case suggests that successful stimulation of the sacral neural outflow may not require intrathecal placement of stimulating electrodes, sensory rhizotomy, or pudendal neurotomy.

Electrical stimulation of the anterior limbic region in Nembutal-anesthetized cats evokes uterine contractions similar to those elicited by the injection of 50–100 mu of synthetic oxytocin. The contractions of the uterus caused by cortical stimulation must be related to release of an oxytocic agent carried through the blood stream, since transection of the spinal cord together with the severance of the vagi did not prevent the contractions. A moderate rise in blood pressure that appeared in the animals with spinal cord transection also suggests release of vasopressin.

Currie, Scott N. and Gregory G. Gonsalves. Right-left interactions between rostral scratch networks generate rhythmicity in the preenlargement spinal cord of the turtle. J. Neurophysiol. 78: 3479–3483, 1997. We examined the rhythmogenic capacity of the midbody D3–D7 spinal cord during stimulation of the rostral scratch reflex in turtles. Fictive scratching was recorded bilaterally as electroneurograms (ENGs) from prehindlimb enlargement nerves [transverse D7 (TD7) and oblique D7 (OD7)] and hip flexor nerves (HF). TD7 and OD7 innervate transverse- and oblique-abdominus muscles, respectively. D3-end preparations had intact spinal cords caudal to a D2–D3 transection site. Unilateral stimulation of the rostral receptive field in D3-end preparations evoked rhythmic bursting in the ipsilateral (ipsi) HF nerve and bilateral rhythmic discharge in the TD7 and OD7 nerves. Right HF bursts were coactive with right TD7 and left OD7 bursts and alternated with left TD7 and right OD7 bursts. D3–D7 preparations received a second spinal transection at the caudal end of segment D7, thus resulting in activation of strictly preenlargement circuitry in response to rostral scratch stimulation and preventing activation of hindlimb enlargement circuitry in segments D8–S2. D3–D7 preparations responded to unilateral stimulation with modulated or tonic discharge in the ipsi TD7 and contralateral (contra) OD7 nerves. In contrast, bilateral stimulation reestablished robust bursting in which coactive right TD7-left OD7 bursts alternated with coactive left TD7-right OD7 bursts. These data imply that TD7 circuit modules make 1) crossed excitatory connections with contra OD7 circuitry, 2) crossed inhibitory connections with contra TD7 circuitry, and 3) uncrossed inhibitory connections with ipsi OD7 circuitry. Our results also suggest that bilateral stimulation evokes rhythmic alternation in the preenlargment cord by simultaneously exciting reciprocally inhibitory circuit modules.
