conclusions acute administration of u. dioica impairs the object-recognition task if it is used only before the training session. this may be due to its modulation on the acquisition processing of object-recognition. u. dioica has no significant effects on the consolidation or retrieval processing stages of the nor task. these results emphasize the unfavorable effect on cognitive function of pr...

Objective(s) Cannabinoids have been implicated in memory deficit. We examined the effect of AM281, cannabinoid antagonist/inverse agonist in prevention of scopolamine-induced cognitive deficit. Materials and Methods  Object recognition task was used to evaluate memory in mice. Exploration time in the first and the second trial was recorded. The differences in exploration between a previously...

since anethum graveolens (dill) has phytoestrogenic compounds and it is proven that estrogens exert beneficial effects on cognition; the aim of this study was to understand if this plant can improve memory performance. male balb/c mice weighing 25-30 g were used in this study and memory was assessed by the novel object recognition task. in this method, the difference in the exploration time bet...

abrupt cessation of morphine leads to withdrawal signs and cognitive deficits. endocannabinoid system is activated during withdrawal; therefore, the aim of the present study was to assess the effects of am281, cannabinoid antagonist/inverse agonist, on memory deficit following spontaneous morphine withdrawal. cognition was evaluated by using the object recognition task. the novel object recogni...

previous reports showed that elevated levels of glucocorticoids following morphine withdrawal play an important role in memory impairment. in addition, glucocorticoid receptor (gr) inhibitors improved memory perfor-mance in morphine withdrawal mice. since mineralocorticoid receptor (mr) and grs complement each other, the aim of the current study was to evaluate the effects of spironolactone on ...

In this study a novel shape descriptor for object recognition is proposed. As preprocessing stage, Canny edge detection [4] applied to input images. Output of detector, namely image, sampled and various number points are selected. Chosen the new descriptor. Proposed composed deviations from average range angle. Shape used as feature extractor output which fed linear classifier. Linear classifie...

Introduction: Certain types of chronic mental stress impair memory. On the other hand, crocin is introduced in the medical literature as an effective component of saffron with remedial effects on memory impairment. This study investigated the effects of crocin on spatial and cognitive memories, locomotor activity, novel recognition conditions and serum corticosterone levels in rats under chroni...

Entorhinal cortex (EC) is one of the first Entorhinal cortex (EC) is one of the first cerebral regions affected in Alzheimer’sdisease (AD). The pathology propagates to neighboring cerebral regions through a prion-likemechanism. In AD, intracellular calcium dyshomeostasis is associated with endoplasmicreticulum (ER) stress. This study was designed to examine hippocampal ER stre...
