Sleep quantitation data on the Neotropical primate species, apart from the squirrel monkey, are still sparse. As such, we have quantitated sleep in the common marmosets (Callithrix jacchus), cotton top tamarins (Saguinus oedipus) and squirrel monkeys (Saimiri sciureus) reared in one primate facility simultaneously, by non-invasive actigraphy. The range in(More)
The site of action for the sleep-promoting effect of prostaglandin (PG) D2 was extensively examined in the brain of adult male rats (n = 231). PGD2 was administered at 100 pmol/0.2 microliter per min for 6 hr (2300-0500 hr) through chronically implanted microdialysis probes or infusion cannulae. Among the administrations of PDG2 by dialysis probes (n =(More)
By his own admission, Albert Einstein, 'started to talk comparatively late ... certainly not younger than three', and also had 'poor memory of words', during his childhood years. If lesions in Brodmann Area 39 of the cerebral hemisphere results in dyslexia, the 1985 report on the study of Einstein's brain that the neuron:glial ratio of Area 39 in the left(More)
Prostaglandin (PG) D2 has been postulated to be an endogenous sleep-promoting factor. Biosynthesis of PGD2 is catalyzed by PGD synthase (prostaglandin-H2 D-isomerase, EC, the activity of which is inhibited by inorganic selenium compounds such as SeCl4 and Na2SeO3. We recently examined the effect of intracerebroventricular administration of these(More)
The beneficial effects in humans of ingesting fish oils have attracted much attention among medical scientists and nutritionists recently. Human studies conducted in populations of Eskimos, Japanese, and Caucasians since 1970 are reviewed in this paper. The evidence shows that a diet rich in omega-3 fatty acids significantly reduces plasma cholesterol and(More)

The objective of this study was to test the hypothesis that activity-behavioral sleep parameters differ between nocturnallyactive owl monkeys and diurnally-active squirrel monkeys which are sympatric and of Bolivian origin. The total sleep time (TST) and sleep episode length (SEL) of 7 adult owl monkey siblings and 4 adult squirrel monkeys were quantitated(More)
Though somnambulism (sleepwalking) is a well-recognized sleep disorder in humans, a biomedical literature search in Medline and Primate Literature bibliographic databases showed no publications on sleepwalking in non-human primates. From this finding, two inferences can be made. First is that somnambulism may be present in non-human primates; but due to(More)
