Background and Objectives: Study of deleterious effect of neurotoxins on the animals' brain is a fascinating research plan. In this project, the damage effect of colchicine on the hippocampal cornu ammonis 1 (CA1) was examined by the studying the hippocampal tissue. Materials and Methods: Injections of colchicine (1-75 μg/rat, intra- hippocampal CA1) were performed in cannulated male Wistar rat...

traumatic brain injury (tbi) is one the most common cause of disability between young adults. these people have been socially isolated during post-surgery traumatic brain injury. in this study we investigated the effect of social isolation on the structural deficits after tbi in the young rats. young rats were divided into control group with social interaction, sham group with social isolation ...

Background and Aim: Learning and memory defect occurs following chronic diabetes with uncontrolled blood glucose. Ginkgo leaf extract improves brain blood flow. Also it contains antioxidant components and has shown beneficial effects in neurological diseases. In this study we investigated the effects of Ginkgo leaf extract on spatial memory impairment and hippocampal neuronal loss caused by dia...

Diurnal preference for evening time has been associated with poorer physical and mental health outcomes. In the current report, perceived loneliness brain structure (hippocampal amygdala volumes) were compared in a large (N = 4684) sample of morning- evening-type individuals. Definite eveningness was increased odds reporting self-perceived lonely evening-types had significantly smaller right hi...

The Dirac field is studied in a Lyra space-time background by means of the classical Schwinger Variational Principle. We obtain the equations of motion, establish the conservation laws, and get a scale relation relating the energy-momentum and spin tensors. Such scale relation is an intrinsic property for matter fields in Lyra background.

Background and Aim: The purpose of the present study is to provide a basis for use Curcuma longa extract as therapeutic agent status epilepticus. Methods: effect on epilepticus in rat model was investigated. rat’s SE induced by pilocarpine evaluated through measurement seizure duration, brain oedema hippocampal oxidative stress this model. Results: In pre-treated with (400mg/kg) water content l...

  In this study, the effect of an experimentally increased excitability in hippocampal neurons, via hippocampal kindling, on amygdala kindling rate was investigated in rats. Animals were divided into 4 groups. In all groups, except group 2, tripolar electrodes were implanted in the amygdala and CAI region of the dorsal hippocampus. Group 2 animals were only implanted with tripolar electrodes in...

introduction: the septal area is an important telencephalic center that plays a prominent role in the learning, emotional sexual behaviour processes and autonomic functions. this area contains two main divisions; lateral (ls) and medial (ms), that receive numerus afferents from hippocampal formation. this study compares, quantitatively distributional pattern of the afferent neurons to these two...
