2. 1. Developmental plasticity of the glutamate synapse: Roles of low frequency stimulation, hebbian induction and the NMDA receptor

   Author : Joakim Strandberg; Göteborgs universitet; []
   Keywords : AMPA receptor; Development; Glutamate; Hippocampus; Long-term depression; Long-term potentiation; NMDA receptor; Synaptic depression;

   Abstract : The glutamate synapse is by far the most common synapse in the brain and acts via postsynaptic AMPA, NMDA and mGlu receptors. During brain development there is a continuous production of these synapses where those partaking in activity resulting in neuronal activity are subsequently selected to establish an appropriate functional pattern of synaptic connectivity while those that do not are elimimated.

4. 2. Plasticity of the developing glutamate synapse in the hippocampus

   Author : Therése Abrahamsson; Göteborgs universitet; []
   Keywords : synaptic plasticity; long-term potentiation; short-term potentiation; silent synapse; development; hippocampus; glutamate;

   Abstract : Synapses are highly plastic, i.e. they have the ability to change their signaling strength both in the short- and long-term (e.g. READ MORE

5. 3. Plasticity in mice nociceptive spinal circuits -role of cell adhesion molecules

   Author : Jonas Thelin; Neurofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long term-potentiation; Cell adhesion molecule; Pain; Somatosensory imprinting; Medicin människa och djur ; Medicine human and vertebrates ; Nociceptive withdrawal reflex; Species differences; Central sensitisation; Mouse strains; Spinal cord;

   Abstract : Introduction: To understand the function of the genes and their products in the pain system, studies will have to deal with complex issues related to intercellular communication, e.g. plasticity in neuronal networks. READ MORE

6. 4. Short- and long-term neuronal plasticity in hippocampal CA1 region of rat

   Author : Fen-Sheng Huang; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glutamate; hippocampus; plasticity; synapse; LTP; LTD; AMPA; NMDA;

   Abstract : The brain is highly plastic, displaying both short- and long-term changes, resulting from developmental processes as well as learning and memory. Moreover, short-term plasticity such as paired pulse facilitation and depression (PPF, PPD) have long been used to monitor the presynaptic versus postsynaptic changes occurring during more lasting processes such as long-term potentiation and depression (LTP, LTD).

7. 5. Roles of SNAP-25 isoforms in activity-dependent long-term synaptic plasticity

   Author : Muhammad Irfan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : SNARE proteins, SNAP-25, syntaxin 1A and VAMP2 constitute the functional units which join together to form the core SNARE complex. The SNARE complex carries out the vital function of membrane fusion of intracellular vesicles with plasma membranes, leading to the release of neurotransmitters in brain neuronal circuits and of hormones in endocrine glands.
