Modulating brain oscillations to drive brain function. [PDF]

PLoS Biology, 2014
Do neuronal oscillations play a causal role in brain function? In a study in this issue of PLOS Biology, Helfrich and colleagues address this long-standing question by attempting to drive brain oscillations using transcranial electrical current ...

Honeybee Brain Oscillations Are Generated by Microtubules. The Concept of a Brain Central Oscillator [PDF]

Frontiers in Molecular Neuroscience, 2021
Microtubules (MTs) are important structures of the cytoskeleton in neurons. Mammalian brain MTs act as biomolecular transistors that generate highly synchronous electrical oscillations. However, their role in brain function is largely unknown.

Interactions of transcranial magnetic stimulation with brain oscillations: a narrative review. [PDF]

Front Syst Neurosci
Brain responses to transcranial magnetic stimulation (TMS) can be recorded with electroencephalography (EEG) and comprise TMS-evoked potentials and TMS-induced oscillations. Repetitive TMS may entrain endogenous brain oscillations. In turn, ongoing brain

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.

Breathing-driven prefrontal oscillations regulate maintenance of conditioned-fear evoked freezing independently of initiation

Nature Communications, 2021
Combining optogenetics, behavioral modelling and neural population analysis, the authors show in mice that during fear-related freezing the olfactory bulb transmits 4 Hz breathing rhythm to the prefrontal cortex where this oscillation organizes local ...

Tuning Neural Synchronization: The Role of Variable Oscillation Frequencies in Neural Circuits

Frontiers in Systems Neuroscience, 2022
Brain oscillations emerge during sensory and cognitive processes and have been classified into different frequency bands. Yet, even within the same frequency band and between nearby brain locations, the exact frequencies of brain oscillations can differ.

The role of gamma oscillations in central nervous system diseases: Mechanism and treatment

Frontiers in Cellular Neuroscience, 2022
Gamma oscillation is the synchronization with a frequency of 30–90 Hz of neural oscillations, which are rhythmic electric processes of neuron groups in the brain.

Mutual Interactions between Brain States and Alzheimer’s Disease Pathology: A Focus on Gamma and Slow Oscillations

Biology, 2021
Brain state varies from moment to moment. While brain state can be defined by ongoing neuronal population activity, such as neuronal oscillations, this is tightly coupled with certain behavioural or vigilant states.

Spatiotemporal Patterns of Adaptation-Induced Slow Oscillations in a Whole-Brain Model of Slow-Wave Sleep

Frontiers in Computational Neuroscience, 2022
During slow-wave sleep, the brain is in a self-organized regime in which slow oscillations (SOs) between up- and down-states travel across the cortex. While an isolated piece of cortex can produce SOs, the brain-wide propagation of these oscillations are

Interactions between stimuli-evoked cortical activity and spontaneous low frequency oscillations measured with neuronal calcium

NeuroImage, 2020
Spontaneous brain activity has been widely used to map brain connectivity. The interactions between task-evoked brain responses and the spontaneous cortical oscillations, especially within the low frequency range of ~0.1 ​Hz, are not fully understood ...
