Synaptic Plasticity: Short Term
Chemical synapses are rarely static transmitters of information between neurons. Their effectiveness waxes and wanes, depending on the frequency of stimulation and the history of prior activity. At most synapses, repetitive highfrequency action potentials (often called a tetanus) initially result in a rapid growth of successive postsynaptic potential (PSP) amplitudes, called synaptic facilitati...
متن کاملShort-term synaptic plasticity.
Synaptic transmission is a dynamic process. Postsynaptic responses wax and wane as presynaptic activity evolves. This prominent characteristic of chemical synaptic transmission is a crucial determinant of the response properties of synapses and, in turn, of the stimulus properties selected by neural networks and of the patterns of activity generated by those networks. This review focuses on syn...
متن کاملAspirin changes short term synaptic plasticity in CA1 area of the rat hippocampus
Introduction: The prostaglandin E2 (PGE2), a cyclooxygenase (COX) product, play critical roles in the synaptic plasticity. Therefore, long term use of COX inhibitors may impair the synaptic plasticity. Considering the wide clinical administration of aspirin and its unknown effects on information processing in the brain, the effect of aspirin and sodium salicylate on the short term synaptic p...
متن کاملShort-term plasticity optimizes synaptic information transmission.
Short-term synaptic plasticity (STP) is widely thought to play an important role in information processing. This major function of STP has recently been challenged, however, by several computational studies indicating that transmission of information by dynamic synapses is broadband, i.e., frequency independent. Here we developed an analytical approach to quantify time- and rate-dependent synap...
متن کاملShort-Term Synaptic Plasticity and Network Behavior
We develop a minimal time-continuous model for use-dependent synaptic short-term plasticity that can account for both short-term depression and short-term facilitation. It is analyzed in the context of the spike response neuron model. Explicit expressions are derived for the synaptic strength as a function of previous spike arrival times. These results are then used to investigate the behavior ...
