An antagonist, 21-009, with high affinity for 5-HT1B receptors and some for beta-adrenergic receptors, induces amnesia in the domestic chick when given centrally before training, using a one-trial passive avoidance task. Nonspecific behavioral effects, or effects upon performance at test, almost certainly do not cause the observed amnesia. The 5-HT2(More)
A great many people suffer from neurological movement disorders that render typical hardware interface devices ineffective. A need exists for a universal interface device that can be trained to accept a wide range of inputs across varying types and severities of movement disorders. In this regard, this paper details the design, testing and optimization of(More)
The beta-adrenergic antagonists sotalol, nadolol and timolol (which act at both beta 1- and beta 2-receptors) induce amnesia in the domestic chick when given systemically after a one trial passive avoidance task. State dependent learning and effects on performance at test (e.g. interference with recall) almost certainly do not cause the observed amnesia.(More)
