Neuronal noise as a physical resource for human cognition

  title={Neuronal noise as a physical resource for human cognition},
  author={Tim N. Palmer and Michael O'Shea},
A new class of energy-efficient digital microprocessor is being developed which is susceptible to thermal noise and consequently operates in probabilistic rather than conventional deterministic mode. Hybrid computing systems which combine probabilistic and deterministic processors can provide robust and efficient tools for computational problems that hitherto would be intractable by conventional deterministic algorithm. These developments suggest a revised perspective on the consequences of ion… 
Optimal causal filtering for 1 /fα-type noise in single-electrode EEG signals
The theoretical background for optimal causal time-domain filtering of deterministic signals embedded in GVZM noise is outlined and some of the early findings concerning the optimal filtering of EEG signals for the detection of steady-state visual evoked potential (SSVEP) responses are presented.
Hidden Quantum Processes, Quantum Ion Channels, and 1/fθ-Type Noise
This letter provides a plausible neurophysical mechanism by which channel and membrane kinetics can give rise to –type noise (something that has been occasionally denied in the literature), as well as a realistic and experimentally testable explanation for the numerical values of the spectral exponents.
Transient Variability in SOI-Based LIF Neuron and Impact on Unsupervised Learning
This paper has studied impact ionization (II)-induced variability both device-to-device (D2D) and cycle- to-cycle (C2C) in the SOI neuron, which enables binary synapses to perform at par with analog synapses, which allows for deterministic weight initialization.
Biophysical Sources of 1/f Noises in Neurological Tissue
This research provides the first simple explanation of 1/f θ-type neurological noise based on biophysical fundamentals and defines a new class of formal latent-variable stochastic processes called hidden quantum models (HQMs) which clarify the theoretical foundations of ion channel signal processing.
Invariant Set Theory and the Symbolism of Quantum Measurement
Elements of a novel theory of quantum physics are developed, synthesising the role of symbolism in describing quantum measurement and in the topological representation of fractal invariant sets in


Noise enhancement of information transfer in crayfish mechanoreceptors by stochastic resonance
The results show that individual neurons can provide a physiological substrate for SR in sensory systems, using external noise applied to crayfish mechanoreceptor cells to demonstrate SR.
Stochastic Simulations on the Reliability of Action Potential Propagation in Thin Axons
The results show that axonal variability is a general problem and should be taken into account when considering both neural coding and the reliability of synaptic transmission in densely connected cortical networks, where small synapses are typically innervated by thin axons.

The main result in this paper establishes the energy savings derived by using probabilistic AND as well as NOT gates constructed from an idealized switch that produces a probabilistic bit (PBIT). A

A perspective on the progress in embracing this somewhat unusual philosophy of innovating computing systems that are designed to be inexact or approximate, in the interests of realizing extreme efficiencies.
Lorenz, G\"{o}del and Penrose: New perspectives on determinism and causality in fundamental physics
Despite being known for his pioneering work on chaotic unpredictability, the key discovery at the core of meteorologist Ed Lorenz’s work is the link between space-time calculus and state-space

A ‘Turing test’ for free will is proposed: a decision-maker who passes this test will tend to believe that he, she, or it possesses free will, whether the world is deterministic or not.
