RATIONALE Associative learning during classical trace eyeblink conditioning has been shown to be regulated by serotonin 5-HT(2A )receptors and to be critically dependent on the integrity of frontal cortex. Chronic administration of 5-HT(2A) ligands has been shown to produce a selective up- or down-regulation of 5-HT(2A) receptors in frontal cortex. (More)
On the basis, chiefly, of anecdotal reports of cases of ocular melanoma (OM) occurring in families with inherited susceptibility to breast cancer due to brca2 germline mutations, we examined the frequency of brca2 alterations in a series of 62 ocular melanoma cases. These cases were preferentially selected on the basis of reported family history of breast(More)
Spot 14 (S14) is a nuclear protein that communicates the status of dietary fuels and fuel-related hormones to genes required for long-chain fatty acid synthesis. In mammary gland, S14 is important for both epithelial proliferation and milk fat production. The S14 gene is amplified in some breast cancers and is strongly expressed in most. High expression of(More)
RATIONALE Associative learning during Pavlovian eyeblink conditioning has been shown to be regulated by 5-HT2A receptors. The existence of inverse agonists that retard learning through an action at the 5-HT2A receptor suggests the existence of constitutive activity at that receptor and that depletion of serotonin should have minimal effects on learning.

RATIONALE Parenteral injections of d-lysergic acid diethylamide (LSD), a serotonin 5-HT(2A) receptor agonist, enhance eyeblink conditioning. Another hallucinogen, (±)-1(2, 5-dimethoxy-4-iodophenyl)-2-aminopropane hydrochloride (DOI), was shown to elicit a 5-HT(2A)-mediated behavior (head bobs) after injection into the hippocampus, a structure known to(More)
RATIONALE Motor movements (head bobs) in the rabbit have been shown to be elicited by LSD-like hallucinogenic drugs through actions at central serotonin 5-HT(2A) receptors, though their central locus remains unknown. Serotonergic innervation of the hippocampus has been suggested to play an important role in motor programming including movements of the head.(More)
Systemic administration of the 5-HT(2A/2C) agonist DOI [(1(2,5-dimethoxy-4-iodophenyl)-2-aminopropane)hydrochloride] in rabbits elicits head bobs and body shakes, which are mediated by 5-HT(2A) and 5-HT(2C) receptors, respectively. This study was designed to determine whether the receptors mediating these behaviors are primarily located in the brain or in(More)
