objective:coriandrum sativum (c. sativum) as a medicinal plant has been pointed to have analgesic, hypnotic and anti-oxidant effects. in the current study, a possible preventive effect of the hydro-alcoholic extract of the plant on neuronal damages was examined in pentylenetetrazole (ptz) rat model of seizure.materials and methods: forty male rats were divided into five main groups and treated ...

diabetes mellitus (dm) is one of the most important metabolic disease causes in many side effects. the decrease of mental abilities and even some form of dementia followed prolonged diabetes has been reported. there are evidences that show hippocampus might be the site of neural involvement in patients with dementia followed diabetes. as hippocampus received main serotonergic efferents from bra...

abstract: ِintroduction: the effect of morphine dependency on learning and spatial memory is controversial. so in this study effect of co-administeration of nitric oxide (no) and morphine in ca3 of hippocampus on learning and spatial memory in morphine dependent rats was investigated. methods: after anaesthetization of male rats, cannulae implanted bilaterally in ca3 of hippocampus. after recove...

introduction: it has been demonstrated that cholecystokinin sulfated octapeptide (cck-8s) can affect synaptic transmission in the hippocampus. because one of the major experimental models to understand the events happening in synaptic plasticity is to study the long-term potentiation (ltp), we decided to investigate the effect of concomitant administration of cck-8s and tetanic stimulation of s...

objective(s) since diabetes mellitus is accompanied by cognitive impairment in diabetic patient and animal models and since lipids play important roles in neuronal membrane composition, structure and function; we intended to evaluate the effect of dietary butter oil on passive avoidance memory of streptoztosin (stz)-induced diabetic rats in this study. materials and methods thirty six adult mal...

objective(s) nicotinic acetylcholine receptors (nachrs) regulate epileptiform activity and produce a sustained pro-epileptogenic action within the hippocampal slices. in the present study, we investigated the effect of nachrs on evoked glutamatergic synaptic transmission in area ca3 and ca1 of rat hippocampal slices to identify possible excitatory circuits through which activation of nachrs pro...

objective(s):neurodegenerative alzheimer’s disease (ad) is associated with profound deficits in synaptic transmission and synaptic plasticity. long-term potentiation (ltp), an experimental form of synaptic plasticity, is intensively examined in hippocampus. in this study we evaluated the effect of aqueous extract of lavender (lavandula angustifolia) on induction of ltp in the ca1 area of hippoc...

introduction: although hippocampus is the most famous brain area involved in temporal lobe epilepsy, hippocampal kindling (hk) develops very slowly. hence, rapid kindling is usually preferred to the traditional kindling and it is widely used. in this article we aimed at finding the optimal stimulus pattern, which yields the fastest hk rate. methods: stimulus patterns with different duration (2,...

the cholinergic and gabaergic .bers of the medial septal/diagonal band of broca (ms/db) area project to the hippocampus and constitute the septo-hippocampal pathway, which has been proven to play a role in learning and memory. in addition, the hippocampus has bidirectional connections with the septum so that to self-regulate of cholinergic input. the activity of septal and hippocampal neurons i...

introduction: preliminary studies have con.rmed reduction in cell death following treatment with antioxidants. according to this .nding we study the relationship between consumption of coq10 and expression of bax and bcl2 in hippocampus following ischemia/reperfusion as proteins involved in cell programmed death or apoptosis. methods: we studied the protective role of coq10 against ischemia-rep...
