The effect of intrahippocampal injection of diarylpropionitrile, a selective estrogen receptor-beta agonist, on passive avoidance learning
Introduction: Neurohormones like testosterone and estradiol have an important role in learning and memory. The hippocampus is essentially involved in learning and memory, and is known to be a target for estradiol actions. Estrogen receptors (ERs) are highly expressed in CA1 of rat hippocampus, and mediate the effects of estrogen on learning and memory. Estradiol receptor belong to a family ...
متن کاملSCH23390, a dopamine D1 receptor antagonist, suppressed scratching behavior induced by compound 48/80 in mice.
To clarify the mechanisms by which compound 48/80 (C48/80) induces scratching behavior, the involvement of dopamine D(1) receptors was investigated. The intracisternal (i.t.) administration of SCH23390 (1.0 μg), a selective dopamine D(1) receptor antagonist, significantly decreased C48/80-induced scratching behavior in mice. These results suggest that dopamine D(1) receptors contribute to scrat...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولبررسی اثر گیرنده های دوپامینی D1 هیپوکامپ پشتی بر روی اثر بهبود بخش نیکوتین روی فراموشی القا شده با اتانول
Background and Objective: Ethanol and nicotine increase dopamine release in different parts of the brain such as the nucleus accumbens and the hippocampus. Dopamine D1 receptors have been detected in dorsal hippocampus known as a key brain region that seems to mediate some behavioral effect of ethanol and nicotine. The present study was carried out to determine the influence of dopamine D1 rece...
متن کاملThe Blockade of D1/D2-Like Dopamine Receptors within the Dentate Gyrus of Hippocampus Decreased the Reinstatement of Morphine-Extinguished Conditioned Place Preference in Rats
Introduction: The hippocampus (HIP), the primary brain structure related to learning and memory, receives sparse but comprehensive dopamine innervations and contains dopamine D1/D2-like receptors. It is demonstrated that dopamine receptors in dentate gyrus (DG) region of HIP have a remarkable function in spatial reward processing. Much less is known about the involvement of HIP and its D1...
