Short-term potentiation of off-responses in turtle horizontal cells
(Elsevier, 1991-04-12)
Depolarizing responses to light off were studied in turtle horizontal cells using intracellular recording in the everted eyecup preparation. In many cells the off-response showed two components (fast and slow) which could ...
Intracellular calcium and hormone release from nerve endings of the neurohypophysis in the presence of opioid agonists and antagonists
(Springer-Verlag, 1992-09)
Rat neural lobes and isolated nerve terminals from the neurohypophysis were stimulated in the presence of different opioid agonists and antagonists. The secretion of arginine vasopressin and oxytocin and rise in cytoplasmic ...
Supraspinal nocifensive responses of cats: Spinal cord pathways, monoamines, and modulation
(Alan R. Liss, Inc.Wiley Periodiocals, Inc., 1988-04-22)
These experiments were conducted to determine (1) whether dorsal and ventral ascending spinal pathways can each mediate unlearned supraspinal nocifensive responses of cats to noxious thermal stimuli and (2) whether ...
Demonstration of sensory innervation of rat tongue with anterogradely transported horseradish peroxidase
(Elsevier, 1986-03-05)
Wheat germ agglutinin-horseradish peroxidase injected into the petrosal ganglion in rats was transported to the posterior tongue in the glossopharyngeal nerve. Labelled fibers innervated the ipsilateral foliate papilla ...
Neurovascular-anastomosed muscle grafts in rabbits: Functional deficits result from tendon repair
(Wiley Subscription Services, Inc., A Wiley Company, 1988-07)
In rabbits, 9 g rectus femoris (RFM) muscles were grafted with tendon repair and with (1) nerves and blood vessels intact, (2) nerves intact and blood vessels anastomosed, or (3) nerves and blood vessels anastomosed. The ...
Development of chorda tympani taste responses in rat
(Wiley Subscription Services, Inc., A Wiley Company, 1981-05-01)
To learn whether neurophysiological taste responses change during structural development of the gustatory system, we recorded from the chorda tympani nerve in rats aged 7 to 92 days after birth. Chemical stimuli applied ...
Glutamine Uptake at the Blood-Brain Barrier Is Mediated by N-System Transport
(Blackwell Science Ltd, 1998-12)
The mechanism of unidirectional transport of glutamine from blood to brain in pentobarbital-anesthetized rats was examined using in situ perfusion. Amino acid uptake into brain across the blood-brain barrier (BBB) is ...
Cocaine: evidence for supraspinal, dopamine-mediated, non-opiate analgesia
(Elsevier, 1989-02-13)
Cocaine (25 mg/kg i.p.) produces analgesia in the rat within 5 min and for a duration of 90 min as determined by the formalin test or for 30 min as determined by the hot plate test. Cocaine analgesia is unaffected by doses ...
Potential sites of interaction between catecholamines and LHRH in the sheep brain
(Elsevier, 1988-01)
A combined immunoperoxidase/immunofluorescence procedure was used to examine potential sites of overlap between catecholamine and LHRH systems in the brains of ewes sacrificed during either anestrous or the breeding season. ...
Improved technique for recording single unit activity in awake animals
(Elsevier, 1980)
An improved system for recording the electrical activity of single neurons in the brain of awake, unanesthetized and unrestrained animals is described, including complete details of construction and use. The advantages of ...
