Neuronal oscillations enhance stimulus discrimination by ensuring action potential precision [PDF]

, 2006
Although oscillations in membrane potential are a prominent feature of sensory, motor, and cognitive function, their precise role in signal processing remains elusive.

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

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.

Neural Oscillators Programming Simplified [PDF]

Applied Computational Intelligence and Soft Computing, 2012
The neurological mechanism used for generating rhythmic patterns for functions such as swallowing, walking, and chewing has been modeled computationally by the neural oscillator. It has been widely studied by biologists to model various aspects of organisms and by computer scientists and robotics engineers as a method for controlling and coordinating ...

Decrease in early right alpha band phase synchronization and late gamma band oscillations in processing syntax in music [PDF]

, 2009
The present study investigated the neural correlates associated with the processing of music-syntactical irregularities as compared with regular syntactic structures in music.

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.

Oscillations in a refractory neural net [PDF]

Journal of Mathematical Biology, 2001
A functional differential equation that arises from the classic theory of neural networks is considered. As the length of the absolute refractory period is varied, there is, as shown here, a super-critical Hopf bifurcation. As the ratio of the refractory period to the time constant of the network increases, a novel relaxation oscillation occurs.

Disrupted dopamine transmission and the emergence of exaggerated beta oscillations in subthalamic nucleus and cerebral cortex [PDF]

, 2008
In the subthalamic nucleus (STN) of Parkinson’s disease (PD) patients, a pronounced synchronization of oscillatory activity at beta frequencies (15–30 Hz) accompanies movement difficulties.

Performance- and stimulus-dependent oscillations in monkey prefrontal cortex during short-term memory [PDF]

, 2009
Short-term memory requires the coordination of sub-processes like encoding, retention, retrieval and comparison of stored material to subsequent input. Neuronal oscillations have an inherent time structure, can effectively coordinate synaptic integration
