in the current study, we assessed the role of transient receptor potential (trp) channels on avoidance memory and anxiety states in ca3 area of the hippocampus. we explored the anxiety and avoidance memory states using test-retest protocol in the elevated plus maze to understand whether trp channels can affect the above mentioned states in ca3 area. to investigate the consolidation phase of mem...

The methanolic leaf extract of Thuja occidentalis was evaluated for possible sedative activities in mice. Sedative activity was evaluated by using hole cross, open field, thiopental sodium-induced sleeping time and elevated-plus maze (EPM) tests at 200mg/kg and 400 mg/kg.  The extract decreased the locomotor activity of mice in hole cross, open field and EPM test and showed the remarka...

Grooming behavior has been reported to be a response to novelty and other stressors. However, studies that sought to identify anxiety-related measures in the elevated plus-maze have not found grooming as a reliable index. Grooming has been implied with dearousal after a stressful experience. In the present work, a detailed investigation of this behavior was performed in a test with a longer dur...

The behavioral activity of 2-methyl-6-(phenylethynyl)-pyridine (MPEP), a selective antagonist of metabotropic glutamate receptor subtype 5 (mGluR5), was assesed in control groups of rats and in rats that underwent short-term hypoxia. MPEP applied intravenously (iv) at the dose of 1 mg/kg was tested using the open field test, the passive avoidance test and the elevated "plus" maze test. MPEP sig...

benzodiazepines (bzds) are widely used in clinical practice as anxiolytics, hypnotics, anticonvulsants, and muscle relaxants. however, they have some undesired effects including memory problems. in continuing our research on novel benzodiazepine ligands, we are looking for ligands with less adverse effects. previously, 4 novel derivatives of 2-phenoxy phenyl-1,3,4-oxadiazole were synthesized as...
