در طی رشد بیشتر نواحی مغز با دو نوع تغییر مواجه می شوند: یکی تغییر از سیناپس الکتریکی به شیمیایی و به موازات آن در سیناپس های گلوتاماترژیک تغییر از سیناپس های با nmda خالص به نوع دو گانه. سیناپس های شیمیایی از جمله سیناپس های گلوتاماترژیک در طی هفته های اول تا سوم بعد از تولد دچار بلوغ و تغییرات فعالیت گیرنده های ampa و nmda می شوند. همزمان با این دوره اصلی تشکیل سیناپس های شیمیایی و افزایش فعا...
introduction: in the present work, spontaneous postsynaptic currents were assessed to investigate the postnatal development of excitatory postsynaptic currents in locus coeruleus neurons. methods: in this study, ampa and nmda receptor-mediated spontaneous synaptic currents in the neurons of locus coeruleus were assessed using whole cell voltage-clamp recording during the first three weeks. resu...
Objective(s): Bisphenol A (BPA), a xenoestrogenic endocrine disrupting agent, is widely used in the production of polycarbonate plastics and has potential adverse effects on the developing nervous system, memory and learning abilities. The protective effect of the crocin, an important active constituent in Crocus sativus L, on memory impairment induced by BPA in rat wa...

Both glutamate receptors and transporters are known to be important in the postsynaptic regulation of glutamate neurotransmission. However, the maturation profile of glutamate transporter EAAC1 and glutamate receptor subunits (NR1, NR2A and NR2B; and GluR 1-4) in functionally activated saccule-related vestibular nuclear neurons of postnatal rats remains unclear. In the present study, conscious ...

Costanza Angelini, Alessandro Morellato, Annalisa Alfieri, Lisa Pavinato, Tiziana Cravero, et al. (see pages [7183–7200][1]) The postsynaptic density (PSD) of excitatory synapses contains an extraordinary number proteins, including AMPA and NMDA receptors, accessory proteins that regulate
اعمال تحریکات مکرر مغناطیسی مغز (rtms) با فرکانس پایین اثر مهاری بر روند کیندلینگ آمیگدال در موش های صحرایی داشته و باعث ممانعت از توسعه و انتشار تشنج از طریق ساختارهای مغزی نظیر ناحیه ca1 هیپوکمپ می شود. در این مطالعه اثر rtms در طی روند کیندلینگ آمیگدال بر ویژگی های الکتروفیزیولوژیک نورون های هرمی ناحیه ca1 هیپوکمپ و جریان های گلوتاماترژیک این ناحیه مورد بررسی قرار گرفت. یک الکترود سه قطبی ...
In this work we study the excitatory AMPA, and NMDA, and inhibitory GABAA receptor mediated dynamical changes in neuronal networks of neonatal rat cortex in vitro. Extracellular network-wide activity was recorded with 59 planar electrodes simultaneously under different pharmacological conditions. We analyzed the changes of overall network activity and network-wide burst frequency between baseli...
Under standard conditions, cultured ventral spinal neurons cluster AMPA- but not NMDA-type glutamate receptors at excitatory synapses on their dendritic shafts in spite of abundant expression of the ubiquitous NMDA receptor subunit NR1. We demonstrate here that the NMDA receptor subunits NR2A and NR2B are not routinely expressed in cultured spinal neurons and that transfection with NR2A or NR2B...
