• Changing associations between events in the environment cause behavioural conflict. The prefrontal cortex and amygdala contribute to adaptive behaviour during Conflict exists popular extinction, reversal learning active avoidance tasks. Deconstructing neural control reveals common features of In complex environments, organisms must respond adaptively situations despite conflicting information...
Introduction: Lead (Pb) is a major pollutant in the environment, which, upon long exposure, can impose a broad range of abnormalities in the structure and function of the brain, especially in the infant. Despite the efforts made in the behavioral effects of lead on the results, there are contradictions and conflicts. In this study, we assessed the effect of chronic exposure to low levels of lea...
Unsupervised cluster analysis is proposed for analysis of active avoidance formation in three groups of albino rats: 1) Intact; 2) With electrolytic lesions of neocortex over the dorsal hippocampus; and 3) with electrolytic lesions of dorsal hippocampus. The term “behavior vector” has been introduced to assess quantitatively the behavior of rats while learning. The proposed approach enables to ...
Soybean lecithin transphosphatidylated phosphatidylserine (SB-tPS) is already known to improve the learning ability of aged or drug-induced amnesic rodents. In this study, its effect on normal adult rodents was evaluated using several learning tasks. Firstly, three behavioral tests (open-field, Y-maze, and active avoidance test) were consecutively carried out after the daily oral administration...
introduction: butylated hydroxytoluene (bht 2, 6-di-tert-butyl-p-cresol) is one of the extensively used antioxidants in the food industry. it is used in low-fat foods, fish products, packaging materials, paraffin, and mineral oils. bht is also widely used in combination with other antioxidants such as bha, propyl gallate, and citric acid for the stabilization of oils and high-fat foods. on the ...
background and objective: based on the effect of chronic metabolic diseases including diabetes mellitus on the learning and memory, this study was designed to assess the usefulness of administration of salvialonic acid b on lessening of learning and memory deficits in streptozotocin (stz)-diabetic rats. materials and methods: male wistar rats were allocated into control, salvialonic acid b-trea...
Effects of a newly synthesized xanthine derivative propentofylline (3,7-dihydro-3-methyl-1-(5-oxohexyl)-7-propyl-1H-purine-2,6-dione) on learning and memory of rodents were examined in the two different paradigms. In a shuttle box active avoidance paradigm, propentofylline (25 mg/kg/day, p.o.) improved the decreased learning ability of 12-month-old spontaneously hypertensive rats. Normotensive ...
