Methodological considerations for studying neural oscillations
European Journal of Neuroscience, 2021 Neural oscillations are ubiquitous across recording methodologies and species, broadly associated with cognitive tasks, and amenable to computational modelling that investigates neural circuit generating mechanisms and neural population dynamics. Because

Contrastive learning and neural oscillations [PDF]
Neural 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.

Neural Oscillations as Representations [PDF]
The British Journal for the Philosophy of Science, 2021 We explore the contribution made by oscillatory, synchronous neural activity to representation in the brain. We closely examine six prominent examples of brain function in which neural oscillations play a central role, and identify two levels of ...

Neural Oscillations in Aversively Motivated Behavior
Frontiers in Behavioral Neuroscience, 2022 Fear and anxiety-based disorders are highly debilitating and among the most prevalent psychiatric disorders. These disorders are associated with abnormal network oscillations in the brain, yet a comprehensive understanding of the role of network ...

Collective oscillations in disordered neural networks [PDF]
Physical Review E, 2010 We investigate the onset of collective oscillations in a network of pulse-coupled leaky-integrate-and-fire neurons in the presence of quenched and annealed disorder. We find that the disorder induces a weak form of chaos that is analogous to that arising

Phase-Dependent Deep Brain Stimulation: A Review
Brain Sciences, 2021 Neural oscillations are repetitive patterns of neural activity in the central nervous systems. Oscillations of the neurons in different frequency bands are evident in electroencephalograms and local field potential measurements.

Separating Neural Oscillations from Aperiodic 1/f Activity: Challenges and Recommendations
bioRxiv, 2021 Electrophysiological power spectra typically consist of two components: An aperiodic part usually following an 1/f power law P∝1/fβand periodic components appearing as spectral peaks. While the investigation of the periodic parts, commonly referred to as

Current findings and perspectives on aberrant neural oscillations in schizophrenia
Psychiatry and Clinical Neurosciences, 2021 There is now consistent evidence that neural oscillation at low‐ and high‐frequencies constitute an important aspect of the pathophysiology of schizophrenia. Specifically, impaired rhythmic activity may underlie the deficit to generate coherent cognition

Modeling neural oscillations [PDF]
Physiology & Behavior, 2002 A brief review of oscillatory activity in neurons and networks is given. Conditions required for neural oscillations are provided. Three mathematical methods for studying the coupling between neural oscillators are described: (i) weak coupling, (ii) firing time maps, and (iii) leaky integrate-and-fire methods.
