Stress-Induced Spatial Memory Deficit Reversed by Basolateral Amygdala NMDA Receptor Inhibition in Male Wistar Rats
Introduction: The present study investigated the role of the Basolateral Amygdala (BLA) N-methyl-D-aspartate (NMDA) receptors in stress-induced spatial memory disturbance among the male Wistar rats. Methods: The male Wistar rats (Average weight =200 g) were cannulated bilaterally in the BLA, and entered the study (n=6-8) after one week. They received seven electro–foot-shock stress sessions o...
متن کاملOrphenadrine-induced convulsive status epilepticus in rats responds to the NMDA antagonist dizocilpine.
BACKGROUND Identification of new molecular targets as well as the new models recapitulating different aspects of pathophysiology of status epilepticus (SE) in humans might prove essential for the breakthrough in the efforts against pharmacoresistance in epilepsy. Recently, we described a new model of generalized convulsive SE induced with orphenadrine (ORPH) in rats with unique characteristics ...
متن کاملIntrahippocampal administration of an NMDA-receptor antagonist impairs spatial discrimination reversal learning in weanling rats.
Systemic administration of MK-801, an NMDA-receptor antagonist, impairs reversal learning in weanling rats [Chadman, K.K., Watson, D.J., & Stanton, M.E. (2006). NMDA-receptor antagonism impairs reversal learning in developing rats. Behavioral Neuroscience, 120(5), 1071-1083]. The brain systems responsible for this effect are not known in either adult or young animals. This study tested the hypo...
متن کاملMultiple limbic regions mediate the disruption of prepulse inhibition produced in rats by the noncompetitive NMDA antagonist dizocilpine.
Prepulse inhibition (PPI), a phenomenon in which a weak prestimulus decreases the startle response to an intense stimulus, provides an operational measure of sensorimotor gating (a process by which an organism filters sensory information) and is diminished in schizophrenia and schizotypal patients. The psychotomimetic phencyclidine and its potent congener dizocilpine are noncompetitive antagoni...
متن کاملThe role of hippocampal (CA1) NMDA receptor on learning and memory in presence and absence of zinc chloride in adult male rats
Introduction: Zinc is an essential trace element that plays an important role in synaptic plasticity and modulating the activity of CNS and involve in learning and memory. Synaptic vesicle zinc in the hippocampus area exerting modulatory effects on NMDA glutamate receptor. Method: In this experiment the effects of NMDA agonist and antagonist administration intra hippocampus on passive avoidan...
