Significance and Translational Value of High-Frequency Cortico-Basal Ganglia Oscillations in Parkinson’s Disease

Journal of Parkinson’s Disease, 2019
The mechanisms and significance of basal ganglia oscillations is a fundamental research question engaging both clinical and basic investigators. In Parkinson’s disease (PD), neural activity in basal ganglia nuclei is characterized by oscillatory patterns

Magnetite particle size and spatial distribution may modulate neural oscillation in the human brain

Scientific Reports
This study proposes a novel hypothesis exploring the potential relationship between magnetite nanoparticle sizes in the human brain and neural oscillation frequencies. Magnetite, a naturally occurring magnetic material found in brain tissue, has been the

Serotonin Modulates Oscillations of the Membrane Potential in Isolated Spinal Neurons from Lampreys [PDF]

, 2002
Studies were performed on spinal neurons from lampreys isolated by an enzymatic/mechanical method using pronase. The effects of 100 µM serotonin (5-HT) on membrane potential oscillations induced by a variety of excitatory amino acids were studied.

Differential modulation of low- and high-frequency mu oscillations during the observation of manual, facial, and non-biological movements

Scientific Reports
Mu suppression - desynchronization of neural oscillations in central EEG electrodes during action execution and observation - has been widely accepted as a marker for neural mirroring.

Synchronized Oscillations During Cooperative Feature Lining in a Cortical Model of Visual Perception [PDF]

, 1991
A neural network model of synchronized oscillations in visual cortex is presented to account for recent neurophysiological findings that such synchronization may reflect global properties of the stimulus.

Emergence of complex oscillatory dynamics in the neuronal networks with long activity time of inhibitory synapses

iScience
Summary: The brain displays complex dynamics, including collective oscillations, and extensive research has been conducted to understand their generation. However, our understanding of how biological constraints influence these oscillations is incomplete.

Parietal gamma oscillations decreased in cognitive biotype of depression

Scientific Reports
Cognitive biotype in depression has long been associated with abnormalities in neural oscillations. Among them, gamma oscillations are widely observed correlates of cognitive dysfunction. However, whether gamma oscillations implement causal mechanisms of
