1. 1. Plasticity of the developing glutamate synapse in the hippocampus

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

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

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

   Författare :Jonas Thelin; Neurofysiologi; []

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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).

5. 4. Neurotransmission and functional synaptic plasticity in the rat medial preoptic nucleus

   Författare :Evgenya Malinina; Staffan Johansson; Eric Hanse; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medial preoptic nucleus; synaptic plasticity; GABA; glutamate; L-type Ca2 channel; Physiology; Fysiologi; fysiologi; Physiology;

   Sammanfattning : Brain function implies complex information processing in neuronal circuits, critically dependent on the molecular machinery that enables signal transmission across synaptic contacts between neurons. The types of ion channels and receptors in the neuronal membranes vary with neuron types and brain regions and determine whether neuronal responses will be excitatory or inhibitory and often allow for functional synaptic plasticity which is thought to be the basis for much of the adaptability of the nervous system and for our ability to learn and store memories.

7. 5. Synaptic plasticity in local networks of neocortical layer 2/3

   Författare :Misha Zilberter; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Neocortical microcircuit; layer 2 3; pyramidal cell; spike timing- dependent plasticity; LTP; LTD; FSN interneuron; retrograde signalling; SAT2;

   Sammanfattning : The neocortex is a hierarchal organ in which information processing takes on place on many levels, from subcellular signalling all the way to neural networks. Neocortical local neuronal networks (microcircuits), composed of interconnected neurons, form elementary information processing units within the cortex. LÄS MER
