Capacity of a Single Spiking Neuron
It is widely believed the neurons transmit information in the form of spikes. Since the spike patterns are known to be noisy, the neuron information channel is noisy. We have investigated the channel capacity of this “Spiking neuron channel” for both of the “temporal coding” and the “rate coding,”which are two main coding considered in the neuroscience[1, 2]. As the result, we’ve proved that th...
متن کاملCapacity of a Single Spiking Neuron Channel
Information transfer through a single neuron is a fundamental component of information processing in the brain, and computing the information channel capacity is important to understand this information processing. The problem is difficult since the capacity depends on coding, characteristics of the communication channel, and optimization over input distributions, among other issues. In this le...
متن کاملSpiking and saturating dendrites differentially expand single neuron computation capacity
The integration of excitatory inputs in dendrites is non-linear: multiple excitatory inputs can produce a local depolarization departing from the arithmetic sum of each input’s response taken separately. If this depolarization is bigger than the arithmetic sum, the dendrite is spiking; if the depolarization is smaller, the dendrite is saturating. Decomposing a dendritic tree into independent de...

متن کاملInformation through a Spiking Neuron
While it is generally agreed that neurons transmit information about their synaptic inputs through spike trains, the code by which this information is transmitted is not well understood. An upper bound on the information encoded is obtained by hypothesizing that the precise timing of each spike conveys information. Here we develop a general approach to quantifying the information carried by spi...
