Fast computation with neural oscillators [PDF]

open access: yesNeurocomputing, 2006
Artificial spike-based computation, inspired by models of computations in the central nervous system, may present significant performance advantages over traditional methods for specific types of large scale problems. In this paper, we study new models for two common instances of such computation, winner-take-all and coincidence detection.

Contrastive Learning and Neural Oscillations [PDF]

open access: yesNeural Computation, 1991
The concept of Contrastive Learning (CL) is developed as a family of possible learning algorithms for neural networks. CL is an extension of Deterministic Boltzmann Machines to more general dynamical systems. During learning, the network oscillates between two phases. One phase has a teacher signal and one phase has no teacher signal.

Optogenetic entrainment of neural oscillations with hybrid fiber probes [PDF]

open access: yes, 2022
Art. 056006, 14 S.OBJECTIVE: Optogenetic modulation of neural activity is a ubiquitous tool for basic investigation of brain circuits. While the majority of optogenetic paradigms rely on short light pulses to evoke synchronized activity of optically ...

Mental imagery of whole-body motion along the sagittal-anteroposterior axis

open access: yesScientific Reports, 2022
Whole-body motor imagery is conceptualised as a mental symbolisation directly and indirectly associated with neural oscillations similar to whole-body motor execution.

Dynamic Neural State Identification in Deep Brain Local Field Potentials of Neuropathic Pain

open access: yesFrontiers in Neuroscience, 2018
In neuropathic pain, the neurophysiological and neuropathological function of the ventro-posterolateral nucleus of the thalamus (VPL) and the periventricular gray/periaqueductal gray area (PVAG) involves multiple frequency oscillations.

Beyond pulsed inhibition: Alpha oscillations modulate attenuation and amplification of neural activity in the awake resting state

open access: yesCell Reports, 2023
Summary: Alpha oscillations are a distinctive feature of the awake resting state of the human brain. However, their functional role in resting-state neuronal dynamics remains poorly understood.

A programmable neural oscillator cell [PDF]

open access: yesIEEE Transactions on Circuits and Systems, 1989
A programmable analog neural oscillator cell architecture is presented. The proposed neuron circuit is of hysteretic neural nature with its implementation based on operational transconductance amplifiers (OTA's). The hysteresis loop as well as the frequency of oscillation are voltage (or current) dependent. The architecture, which involves two OTA's, a

Predicting psychosis in at-risk patients using abnormal neural oscillations and synchrony in conjunctions with machine learning algorithms [PDF]

open access: yes, 2016
In the last 20 years, there has been a marked increase in interest in the early detection and treatment of psychosis. Despite the various potential “prodromes” that have been identified and have helped to increase the accuracy in the detection of persons

Neural components underlying subjective preferential decision making [PDF]

open access: yes, 2010
The objectives of the current study were twofold: (i) to investigate the neural precursors of the formation of a subjective preference of facial stimuli, and (ii) to characterize the spatiotemporal brain activity patterns distinguishing between preferred
