The cyclic AMP response to catecholamines in rat cortical slices is mediated by a beta adrenergic receptor which is coupled to adenylate cyclase and an alpha adrenergic receptor which potentiates the response to beta receptor stimulation. The present studies examined the effects of repeated restraint stress, adrenocorticotropin or desmethylimipramine(More)
The cyclic AMP response to catecholamines in the rat cerebral cortex is mediated by both beta- and alpha-adrenoceptors. The beta-receptors cause a direct activation of adenylate cyclase whereas the alpha alpha-receptors play a modulatory role and act by potentiating the response to beta stimulation. The present study investigated whether the functions of(More)
l-Dopa continues to be the gold drug in Parkinson’s disease (PD) treatment from 1967. The failure to translate successful results from preclinical to clinical studies can be explained by the use of preclinical models which do not reflect what happens in the disease since these induce a rapid and extensive degeneration; for example, MPTP induces a severe(More)
Amphetamine locomotor sensitization is an animal model for the study of addiction and schizophrenia. The antipsychotic clozapine blocks the hyperlocomotion induced by an acute injection of amphetamine, but its effect on locomotor sensitization after repeated amphetamine administration remains unknown. In the present study we investigate the effect of(More)
In this paper, the development of a subsystem in an educational game is presented. The educational game cited here; "Geometry Virtual Museum" (GVM) is focused on geometry learning which is aimed at students to help enhance their knowledge in this mathematical area. In-game information is generated about the learning activity of the students. Information(More)
The cyclic adenosine monophosphate response to catecholamines in the rat brain is mediated by beta-adrenergic receptors which activate adenylate cyclase and by alpha-adrenergic receptors which potentiate the response to beta-stimulation. We have found that the alpha-potentiation effect in the olfactory bulb is 2-3X greater than in other forebrain areas.(More)
