Short-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 کاملSynaptic 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 presynaptic plasticity.
Different types of synapses are specialized to interpret spike trains in their own way by virtue of the complement of short-term synaptic plasticity mechanisms they possess. Numerous types of short-term, use-dependent synaptic plasticity regulate neurotransmitter release. Short-term depression is prominent after a single conditioning stimulus and recovers in seconds. Sustained presynaptic activ...
متن کاملEffects of Neonatal C-Fiber Depletion on Interaction between Neocortical Short-Term and Long-Term Plasticity
Introduction: The primary somatosensory cortex has an important role in nociceptive sensory-discriminative processing. Altered peripheral inputs produced by deafferentation or by long-term changes in levels of afferent stimulation can result in plasticity of cortex. Capsaicin-induced depletion of C-fiber afferents results in plasticity of the somatosensory system. Plasticity includes short-term...
متن کاملPitch Detection Using the Short—term Phase Spectrum
A new frequency domain method for determining the fundamental frequency of speech is presented in this paper. This method uses the information contained in the short—term phase spectrum whereas the previous methods were limited to the amplitude spectrum. The short—term spectrum is computed by DFT and it is interpreted as the output of a bank of band—pass overlapping filters. Harmonic components...
