A self-governing state of the Windward Islands in the West Indies, comprising Saint Vincent and the northern islets of the Grenadines. Its capital is Kingstown. It is one of the original homes of the Carib Indians supposed to have been sighted by Columbus in 1498. It was in English hands from 1627 till held by the French 1779-83. Saint Vincent subsequently became a British possession and, with other nearby British territories, was administered by the Governor of the Windward Islands till 1959. It attained a measure of independence in 1969 but achieved full independence as Saint Vincent and the Grenadines in 1979. Saint Vincent was the 4th century Spanish martyr on whose feast day Columbus discovered the island. Grenadines is derived from the Spanish kingdom of Granada. (From Webster's New Geographical Dictionary, 1988, p1054 & The Europa World Year Book 1993, p2441)
A benign familial disorder, transmitted as an autosomal dominant trait. It is characterized by low-grade chronic hyperbilirubinemia with considerable daily fluctuations of the bilirubin level.
A gram-negative, rod-shaped to coccoid bacterium. It is the etiologic agent of SCRUB TYPHUS in humans and is transmitted by mites from rodent reservoirs.
An acute infectious disease caused by ORIENTIA TSUTSUGAMUSHI. It is limited to eastern and southeastern Asia, India, northern Australia, and the adjacent islands. Characteristics include the formation of a primary cutaneous lesion at the site of the bite of an infected mite, fever lasting about two weeks, and a maculopapular rash.
A syndrome characterized by HYPERPIGMENTATION, enlarging pituitary mass, visual defects secondary to compression of the OPTIC CHIASM, and elevated serum ACTH. It is caused by the expansion of an underlying ACTH-SECRETING PITUITARY ADENOMA that grows in the absence of feedback inhibition by adrenal CORTICOSTEROIDS, usually after ADRENALECTOMY.
A course of study offered by an educational institution.
The study of the structure, growth, activities, and functions of NEURONS and the NERVOUS SYSTEM.
Abstract standards or empirical variables in social life which are believed to be important and/or desirable.
The observable response an animal makes to any situation.
The continuous developmental process of a culture from simple to complex forms and from homogeneous to heterogeneous qualities.
The science of language, including phonetics, phonology, morphology, syntax, semantics, pragmatics, and historical linguistics. (Random House Unabridged Dictionary, 2d ed)
The period of history before 500 of the common era.
A verbal or nonverbal means of communicating ideas or feelings.
Imaging techniques used to colocalize sites of brain functions or physiological activity with brain structures.
A meshlike structure composed of interconnecting nerve cells that are separated at the synaptic junction or joined to one another by cytoplasmic processes. In invertebrates, for example, the nerve net allows nerve impulses to spread over a wide area of the net because synapses can pass information in any direction.
Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
A technique of inputting two-dimensional images into a computer and then enhancing or analyzing the imagery into a form that is more useful to the human observer.
Neural tracts connecting one part of the nervous system with another.
The knowledge or perception that someone or something present has been previously encountered.
