Instrumental learning of gastric vascular tonicity responses.

چکیده
Male rats with a chronically implanted device that allowed photoelectric plethysmographic measures to be made of the stomach wall were trained while paralyzed with d-tubocurarine and being artificially respirated. One group was reinforced by avoidance of and/or escape from electric shocks to the tail, whenever increases in the transmission of light through the stomach wall occurred during a CS; another group was reinforced for decreases. Reliable changes in the rewarded direction were learned. These results are interpreted as evidence for the instrumental learning of a gastric response which, in the light of control experiments, very probably was a vasomotor one producing changes in the amount of blood in the stomach wall.

This study examined the effects of bilateral excitotoxic lesions of the nucleus accumbens core (NAc-co), dorsomedial striatum (DMS) or dorsolateral striatum (DLS) of rats on the learning and extinction of Pavlovian and instrumental components of conditioned avoidance responses (CARs). None of the lesions caused sensorimotor deficits that could affect locomotion. Lesions of the NAc-co, but not D...
متن کاملTonicity-independent regulation of the osmosensitive transcription factor TonEBP (NFAT5).
Tonicity-responsive enhancer binding protein (TonEBP/nuclear factor of activated T-cells 5 [NFAT5]) is a Rel homology transcription factor classically known for its osmosensitive role in regulating cellular homeostasis during states of hypo- and hypertonic stress. A recently growing body of research indicates that TonEBP is not solely regulated by tonicity, but that it can be stimulated by vari...

Vascular aging plays an important role in the mortality of the elderly, but vascular aging can be dependent on other factors such as diseases. Various diseases such as Alzheimer, diabetes, thalassemia, and other diseases affect the mechanisms of vascular aging. It will harm the recovery process of these patients. There are methods for measuring vascular aging such as instrumental measurements a...
متن کاملMononuclear phagocyte system depletion blocks interstitial tonicity-responsive enhancer binding protein/vascular endothelial growth factor C expression and induces salt-sensitive hypertension in rats.
We showed recently that mononuclear phagocyte system (MPS) cells provide a buffering mechanism for salt-sensitive hypertension by driving interstitial lymphangiogenesis, modulating interstitial Na(+) clearance, and increasing endothelial NO synthase protein expression in response to very high dietary salt via a tonicity-responsive enhancer binding protein/vascular endothelial growth factor C re...
متن کاملTransfer of Stimulus Control across Instrumental Responses is attenuated by Extinction in Human Instru- mental Conditioning
Transfer of behavioral control by a discriminative stimulus (S D ) between different instrumental responses trained with the same outcome has been consistently observed in nonhuman animals, regardless of whether the discriminative stimulus and the instrumental response have undergone extinction. Based on this result, it has been proposed that extinction of nonhuman instrumental learning does no...
