| insular | Relating to any insula, especially the island of Reil. (05 Mar 2000) |
|---|---|
| insular area | 1. An oval region of the cerebral cortex overlying the extreme capsule, lateral to the lenticular nucleus, buried in the depth of the fissura lateralis cerebri (sylvian fissure). Synonym: insular area, insular cortex, island of Reil. Synonym: island. 3. Any circumscribed body or patch on the skin. Origin: L. Island (05 Mar 2000) |
| insular arteries | Branches from the insular part of the middle cerebral artery distributed to the cortex of the insula. Synonym: arteriae insulares. (05 Mar 2000) |
| insular cortex | 1. An oval region of the cerebral cortex overlying the extreme capsule, lateral to the lenticular nucleus, buried in the depth of the fissura lateralis cerebri (sylvian fissure). Synonym: insular area, insular cortex, island of Reil. Synonym: island. 3. Any circumscribed body or patch on the skin. Origin: L. Island (05 Mar 2000) |
| insular gyri | The short gyri of insula and long gyrus of insula. Synonym: gyri insulae. (05 Mar 2000) |

| insular sclerosis | <neurology> Neurodegenerative disease characterised by the gradual accumulation of focal plaques of demyelination particularly in the periventricular areas of the brain. Peripheral nerves are not affected. Onset usually in 3rd or 4th decade with intermittent progression over an extended period. Cause still uncertain. (18 Nov 1997) |
| insular veins | Veins draining the cortex of the insula, tributaries to the deep middle cerebral vein. Synonym: insular veins. (05 Mar 2000) |
| adaptor hypothesis | A hypothesis, proposed by F.H.C. Crick, that an adaptor molecule must be present between the information-containing DNA and the protein being synthesised. (05 Mar 2000) |
| altered self hypothesis | The hypothesis that the T-cell receptor in MHC mediated phenomena recognises a syngeneic MHC Class I or Class II molecule after modification by a virus or certain chemicals. See: MHC restriction. (18 Nov 1997) |
| alternative hypothesis | In Neyman-Pearson testing of a hypothesis, the hypothesis or family of hypotheses about the numerical value of a parameter if and only if the null hypothesis is rejected as untenable. (05 Mar 2000) |
| autocrine hypothesis | That tumour cells containing viral oncogenes may have encoded a growth factor, normally produced by other cell types, and thereby produce the factor autonomously, leading to uncontrolled proliferation. (05 Mar 2000) |
| Avogadro's hypothesis | <physics> The hypothesis that equal volumes of two different gases at the same temperature and pressure contain the same number of molecules. (02 Jan 1998) |
| Bayesian hypothesis | An array of surmised values of a parameter to be severally explored in the light of a current set of data, with logical symmetry being preserved among all. The merits of each hypothesis entertained are based on quantity, the prior probability. The probability of the data conditional on the hypothesis is computed as the conditional probability for each; the product of the two for each hypothesis is the joint probability, and the ratio of each joint probability to the sum of all the joint probabilities is the posterior probability for that hypothesis. Unlike the Neyman-Pearson test of hypotheses, the answer is a statement about the hypothesis, not about the sample conditional on the hypothesis. No hypothesis is preferred or prevails by default. The procedure may be applied recursively any number of times, as the data becomes available. (05 Mar 2000) |
