introduction: considering the antiepileptogenic effects of repeated transcranial magnetic stimulation (rtms), the effect of rtms applied during amygdala kindling on spontaneous activity of hippocampal ca1 pyramidal neurons was investigated. materials and methods: a tripolar electrode was inserted in basolateral amygdala of male wistar rats. after a recovery period, animals received daily kindli...
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...

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 ...
Objective(s): Crocin influences many biological functions including memory and learning. The present study was aimed to investigate the effects of crocin on learning and memory impairments in streptozotocine-induced diabetic rats. Materials and Methods: Diabetes was induced by intraperitoneal (IP) injection of streptozotocin (STZ, 45 mg/kg). Transfer latency (TL) paradigm in elevated plus-maze ...
Introduction MDMA or ecstasy is a derivative of amphetamines used mostly by young people worldwide. Although the acute effects of this drug are known, the effect of chronic administration is not well studied. Therefor the aim of this study was to determine the effects of repeated (long term) administration of MDMA on rats' memory and their hippocampal cell density. Method: Young adult male W...
Cover Illustration: Automated detection and reconstruction of astrocytic domain (cyan) in 3D volume CA1 that was injected with a viral vector to induce the expression tdTomato (purple) astrocytes, then made transparent by CLARITY. We imaged thousands hippocampal provide quantitative characterization excitatory neurons content, proximity inhibitory neurons. (See Refaeli R., et al, https://doi.or...
Long-term potentiation (LTP) is a form of activity-dependent plasticity that occurs during learning. Potassium channels are the most diverse group of all ion channels that related to synaptic plasticity. Small-conductance calcium-activated potassium channels (SKs) are found in hippocampal CA1 neurons and by inhibiting of postsynaptic potentials are involved in synaptic transmission impairment. ...
This study was conducted to evaluate the effect of soy milk on serum 17- β estradiol level and number of neurons in cerebral cortex and hippocampus as well as determination of the ratio of neurons in cortical and hippocampal regions in neonatal ovariectomized rats. Thirty female rats (one day old) were divided into six groups of five. At day 7, ovariectomy surgery was performed in four groups a...
