نقش سلول های گلیا در پاسخ سیناپسی پایه و شکل پذیری سیناپسی کوتاه مدت ناحیه CA1 هیپوکمپ
Background and purpose: Glial cells seem to play role in synaptic plasticity because they have the ability to release trophic factors and gliotransmitters and respond to neurotransmitters. They also play important role in synaptic space homeostasis. In this study, the role of hippocampal glial cells in baseline synaptic response and short term synaptic plasticity were investigated. Material...
متن کاملTransgenic inhibition of synaptic transmission reveals role of CA3 output in hippocampal learning.
The hippocampus is an area of the brain involved in learning and memory. It contains parallel excitatory pathways referred to as the trisynaptic pathway (which carries information as follows: entorhinal cortex --> dentate gyrus --> CA3 --> CA1 --> entorhinal cortex) and the monosynaptic pathway (entorhinal cortex --> CA1 --> entorhinal cortex). We developed a generally applicable tetanus toxin-...
متن کاملThe effect of ketamine on NMDA receptor-mediated LTP depends on ketamine effects on non-NMDA-mediated synaptic transmission in CA1 area of rat hippocampal slices
It has been reported that ketamine as an uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist has also non-NMDA receptor antagonist properties. We recently found that ketamine (20 ?M) affected differently induction of NMDA receptor-mediated long-term potentiation (LTP) when administered 30 min prior to tetanic Primed-Bursts (PBs) stimulation. On the other hand, ketamine also influenced...
متن کاملP3: Mechanisms of TrkB-Mediated Hippocampal Long-Term Potentiation in Learning and Memory
Long-term potentiation (LTP) is a process that certain types of synaptic stimulation lead to a long-lasting enhancement in the strength of synaptic transmission. Studies in recent years indicate the importance of molecular pathways in the development of memory and learning. Tropomyosin receptor kinase B (TrkB) is a member of the neurotrophin receptor tyrosine kinase family, that its ligand is b...
