Water Deprivation: A New Migraine Precipitant

Headache: The Journal of Head and Face Pain, 2005
Fifty migraineurs were asked if insufficient fluid intake could provoke their migraine attacks. Twenty replied “yes,” 7 were doubtfully positive, and 23 said “no.” In addition 14 of 45 migraineurs at a meeting of the British Migraine association (UK) also recognized fluid deprivation as one of their migraine triggers.

Light Reinforcement as a Function of Water Deprivation

Psychological Reports, 1958
There are several studies (3, 4, 5 ) which attest to the efficacy of light as a reinforcing stimulus with non-deprived animals. However, Kling, et al. ( 5 ) noted that light presentation did not appear to strengthen bar pressing when the subjects, albino rats, were water deprived.

Effects of water deprivation on the water content of cattle skin

International Journal of Biometeorology, 1968
In cattle the water content of the skin was determined (1) in the normal animals; (2) after a 3-day period of water deprivation (dehydration); (3) one hour after the water deprived animals had resumed drinking (rehydration)and (4) one hour after the beginning of infusion of water into the rumen of normal animals (overhydration). Dehydration reduced the

Mechanism of the Decreased Erythropoiesis in the Water Deprived Rat

British Journal of Haematology, 1979
Radioiron uptake by erythrocytes, metabolic rate, erythropoietin formation during hypoxia and erythroid responsiveness to exogenous erythropoietin were determined in both starved and water deprived rats. The feed intake showed a marked and progressive reduction during water deprivation.

Interaction of mercury and water deprivation on the hematology of chickens

Journal of Toxicology and Environmental Health, 1986
Four-week-old male chickens were subjected to one of the following treatments: 0 ppm mercury (Hg) plus water ad libitum, 0 ppm Hg plus limited water (LW), 500 ppm Hg plus water ad libitum, and 500 ppm Hg plus LW. Exposure was for each of the following time intervals: 0-3, 0-6, 0-9, 0-12, and 0-15 d.

Naloxone: Effects on food and water consumption in the non-deprived and deprived rat

Psychopharmacology, 1980
Naloxone (0.5--5 mg/kg) reduced both food and water intake in non-deprived male rats, tested in the dark phase of the light-dark cycles in their home cages. These effects were transient; food and water-intake were restored to control levels by the end of the 8-h test period. The effects were also not dose-related.

Learned aversion to mannitol in water-deprived rats

Physiology & Behavior, 1984
Mannitol, a non-absorbent compound may suppress free drinking in rats. It was suggested that the osmotic accumulation of water in the intestine produced a satiety signal by distending the wall of the gut, which resulted in the reduction of intake. However, we never obtained this suppression during the first exposure to mannitol in water deprived rats ...

Effects of acute food and/or water deprivation on muricide

Physiology & Behavior, 1985
The present experiment was designed to test certain predictions derived from models of interactions between muricide and appetitive behaviors proposed earlier by Russell and Singer [8,9]. One of the major features of the models centered on whether the two types of behavior are inevitably related.

The Effect of Food and Water Deprivation and Satiation on Recognition

The American Journal of Psychology, 1979
Food and water deprived and satiated subjects, as well as control subjects, were shown words presented tachistoscopically for .01 sec until word recognition. Five food-relevant, five water-relevant, and five neutral (animal) words of high string frequency were matched for letter confusability and letter predictability. Analyses of the data, in terms of

Water Balance in Infants During Water Deprivation

American Journal of Diseases of Children, 1962
Introduction Loss of body water occurs normally through the skin, respiratory passages, intestine, and kidney. Abnormal losses of hypotonic fluid may result from diarrhea and vomiting, sweating, and hyperpnea. Under these circumstances, hypertonicity of residual body fluids is partially counteracted by renal conservation of water relative to solute ...
