Abstract

Certain aspects of the present disclosure support techniques for modulating neuronal firing via noise control. The response curve of a typical neuron with a threshold can transition from never firing to always firing with very small changes in the neuron's input, thereby limiting the range of excitable input patterns for the neuron. The slope of the neuron response curve can be reduced by introducing local, regional and global noise terms. This may enable a larger set of input spike patterns to be effective in firing the neuron, that is, enable the neuron to respond to a large range of input patterns rather than the inherently smaller set of patterns in the absence of noise.

Description

technical field [0001] Certain aspects of the present disclosure relate generally to neural systems engineering, and more specifically, to methods and apparatus for modulation of neuronal firing via noise control. Background technique [0002] One of the fundamental properties of a neuron is its ability to be excited such that it can generate or emit an output signal, typically in the form of an action potential. Internal neuron settings (i.e. thresholds) can control whether an action potential is fired or not. If the spatial-temporal aggregate input signal is below the threshold (ie, under the threshold), then the neuron will not fire. However, if the aggregated input signal exceeds (ie is on) the threshold, then the neuron will fire one or more action potentials. [0003] In a typical neuron with a threshold, the response (input-output) curve can transition from never firing to always firing with very small changes in the input, thereby limiting the range of excitable in...
