Decoding synapses.
The strength of many synapses is modified by various use and time-dependent processes, including facilitation and depression. A general description of synaptic transfer characteristics must account for the history-dependence of synaptic efficacy and should be able to predict the postsynaptic response to any temporal pattern of presynaptic activity. To generate such a description, we use an appr...
متن کاملDynamical Synapses Enhance Neural Information Processing: Mobility, Memory and Decoding
Neuronal connection efficacy exhibits two forms of short-term plasticity, namely, short-term depression (STD) and short-term facilitation (STF). They have time constants residing between fast neural signaling and slow learning, and may serve as substrates for neural systems manipulating temporal information in relevant time scales. The present study investigates the impact of STD and STF on the...
متن کاملComdined Turbo Block Decoding and Equalisation
In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...

متن کاملSynapses: Glia help synapses form and function
Glial cells and neurons are intimately juxtaposed throughout the nervous systems of all higher animals. Some instances of functional partnership between glial cells and neurons — such as the electrical insulator role of the myelinating Schwann cell — are very well understood, but most are only beginning to be explored. Many structural, biochemical and physiological clues have pointed to the syn...
