Tonic inhibition of small intestinal motility by nitric oxide
Journal of the Autonomic Nervous System, 1993The effects of blocking nitric oxide synthase with the arginine analog N omega-nitro-L-arginine (L-NNA) were investigated in anaesthetized cats, vagotomized and pretreated with guanethidine and atropine. Spontaneous NANC jejunal motility (recorded as the volume changes of an intraluminal balloon) was markedly increased in a dose-dependent and ...

In experiments described in [143], fast-firing inhibitory interneurons in the barrel cortex of mice, the part of the mouse brain that processes input from the whiskers, were driven to synchronize at 40 Hz, using optogenetic techniques. (In general, optogenetic techniques involve genetically sensitizing neurons to light, then using light to control ...

Tonic inhibition of thermoregulation in the decerebrate monkey (Saimiri sciureus)
Experimental Neurology, 1979Abstract In monkeys ( Saimiri sciureus ) acute truncation of the brain stem just caudal to the hypothalamus or rostral to the pons results in a preparation which rapidly loses body heat without shivering, piloerection, and vasoconstriction of cutaneous vessles.

Tonic inhibition by orphanin FQ/nociceptin of noradrenaline neurotransmission in the amygdala
European Journal of Pharmacology, 2004The present microdialysis study investigated whether nociceptin/orphanin FQ exerts a tonic inhibition of the release of noradrenaline in the basolateral nucleus of the amygdala in awake rats. The non-peptide competitive nociceptin/orphanin FQ (N/OFQ) peptide receptor antagonist J-113397 (20 mg/kg i.p.) induced an increase in the release of ...

Somatostatin tonically inhibits growth hormone secretion in domestic fowl
Journal of Endocrinology, 1986ABSTRACT Passive immunization of immature chickens with sheep somatostatin (SRIF) antiserum promptly increased the basal plasma GH concentration and augmented TRH-induced GH secretion. Although exogenous SRIF had no inhibitory effect on the basal GH concentration in untreated birds or birds pretreated with non-immune sheep serum, it suppressed ...

Serotonin neurons are necessary for tonic sodium intake inhibition
American Journal of Physiology-Regulatory, Integrative and Comparative PhysiologyThis study demonstrates a fundamental role for serotonergic neurons in limiting sodium intake. Mice with genetic deletion of serotonin-producing neurons consume more salt, indicating that serotonergic neurons act like a brake to restrain sodium appetite. These findings advance our understanding of how the brain controls salt-seeking behavior.

Is the Tonic Decerebrate Inhibition of Reflex Paths Mediated by Monoaminergic Pathways?
Acta Physiologica Scandinavica, 1968AbstractIn unanesthetized decerebrate cats the effect of monoamine blockers has been investigated on the decerebrate tonic inhibitory control of transmission from the FRA (flexor reflex afferents) to motoneurones. No certain effect is obtained after injection of phenoxybenzamine but S‐hydroxytryptamine antagonists (BOL or Deseril) give a partial ...

Direct tonic inhibition of insulin secretion by central nervous system
American Journal of Physiology-Endocrinology and Metabolism, 1983An experimental animal model was developed to investigate the influence of the central nervous system (CNS) on insulin secretion via direct innervation to the pancreas. This model eliminates any indirect CNS effect on the pancreas by hormonal factors.

The role of recurrent and presynaptic inhibition in the depression of tonic motoneuronal activity
Pfl�gers Archiv European Journal of Physiology, 19721. The mechanism of motoneuronal depression induced by increasing the number of electrically stimulated gastrocnemius afferents was studied in decerebrate cats. 2. Increasing the threshold stimulus intensity for the group I afferents gradually up to two times caused a linear increase in amplitude of the nerve action potentials recorded ...

[Tonic mechanisms of efferent inhibition in the frog labyrinth].
Bollettino della Societa italiana di biologia sperimentale, 1981Activation of the efferent system of the isolated group labyrinth inhibits the afferent EPSP and spike discharge by releasing ACh, which opens the Cl- channel of the hair cells membrane. Experiments in which increasing amounts of Cl- in the bath are replaced by equivalent amounts of Br-, NO2-, NO3-, CH3 CO2-, SO4(2-), CH3CH2CO2-, CH3(CH2)2CO2-, CH3(CH2)
