A programmable neural oscillator cell [PDF]
IEEE 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

Fast computation with neural oscillators [PDF]
Neurocomputing, 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.

Balance between pallidal neural oscillations correlated with dystonic activity and severity
Neurobiology of Disease, 2023 Background and objective: The balance between neural oscillations provides valuable insights into the organisation of neural oscillations related to brain states, which may play important roles in dystonia.

Optimal entrainment of neural oscillator ensembles [PDF]
Journal of Neural Engineering, 2012 In this paper, we derive the minimum-energy periodic control that entrains an ensemble of structurally similar neural oscillators to a desired frequency. The state space representation of a nominal oscillator is reduced to a phase model by computing its limit cycle and phase response curve, from which the optimal control is derived by using formal ...

Disharmony in neural oscillations [PDF]
Journal of Neurophysiology, 2017 Cross-frequency phase coupling (PPC) may play an important role in neural processing and cognition. However, a new study unveils a statistical bias in how PPC is detected in neural recordings, questions prior evidence for PPC in hippocampus, and shows PPC tests are dramatically flawed by their confounds with oscillation harmonics.

A dynamical systems approach for estimating phase interactions between rhythms of different frequencies from experimental data. [PDF]
PLoS Computational Biology, 2018 Synchronization of neural oscillations as a mechanism of brain function is attracting increasing attention. Neural oscillation is a rhythmic neural activity that can be easily observed by noninvasive electroencephalography (EEG). Neural oscillations show

Large-scale network dynamics of beta-band oscillations underlie auditory perceptual decision-making [PDF]
Network Neuroscience, 2017 Perceptual decisions vary in the speed at which we make them. Evidence suggests that translating sensory information into perceptual decisions relies on distributed interacting neural populations, with decision speed hinging on power modulations of the ...

Deficits in high- (>60 Hz) gamma-band oscillations during visual processing in schizophrenia [PDF]
, 2013 Current theories of the pathophysiology of schizophrenia have focused on abnormal temporal coordination of neural activity. Oscillations in the gamma-band range (>25 Hz) are of particular interest as they establish synchronization with great precision in

Striatal cholinergic interneurons generate beta and gamma oscillations in the corticostriatal circuit and produce motor deficits [PDF]
, 2016 Cortico-basal ganglia-thalamic (CBT) neural circuits are critical modulators of cognitive and motor function. When compromised, these circuits contribute to neurological and psychiatric disorders, such as Parkinson's disease (PD).
