Phase dependent modulation of tremor amplitude in essential tremor through thalamic stimulation [PDF]

, 2013
High frequency deep brain stimulation of the thalamus can help ameliorate severe essential tremor. Here we explore how the efficacy, efficiency and selectivity of thalamic deep brain stimulation might be improved in this condition.

Propagating patterns of intrinsic activity along macroscale gradients coordinate functional connections across the whole brain

NeuroImage, 2021
The intrinsic activity of the human brain, observed with resting-state fMRI (rsfMRI) and functional connectivity, exhibits macroscale spatial organization such as functional networks and gradients.

Intrinsic Coupling Modes: Multiscale Interactions in Ongoing Brain Activity [PDF]

Neuron, 2013
Intrinsic coupling constitutes a key feature of ongoing brain activity, which exhibits rich spatiotemporal patterning and contains information that influences cognitive processing. We discuss evidence for two distinct types of intrinsic coupling modes which seem to reflect the operation of different coupling mechanisms.

Regional healthy brain activity, glioma occurrence and symptomatology

, 2022
It is unclear why exactly gliomas show preferential occurrence in certain brain areas. Increased spiking activity around gliomas leads to faster tumour growth in animal models, while higher non-invasively measured brain activity is related to shorter ...

The restless brain: how intrinsic activity organizes brain function [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2015
Traditionally studies of brain function have focused on task-evoked responses. By their very nature such experiments tacitly encourage a reflexive view of brain function. While such an approach has been remarkably productive at all levels of neuroscience, it ignores the alternative possibility that brain functions are mainly intrinsic and ongoing ...

Common variants contribute to intrinsic human brain functional networks [PDF]

, 2022
The human brain forms functional networks of correlated activity, which have been linked with both cognitive and clinical outcomes. However, the genetic variants affecting brain function are largely unknown.

Aberrant Dynamics of Regional Coherence Measured by Resting-State fMRI in Children With Benign Epilepsy With Centrotemporal Spikes (BECTS)

Frontiers in Neurology, 2021
Objective: To explore the dynamic features of intrinsic brain activity measured by fMRI in children with benign epilepsy with centrotemporal spikes (BECTS) and examine whether these indexes were associated with behaviors.Methods: We recruited 26 children

The brain's intrinsic activity and inner time consciousness in schizophrenia [PDF]

World Psychiatry, 2014
How is it possible that the brain's neural activity is directly dependent upon environmental contingencies? This is a central question raised by Cacioppo et al's impressive target paper 1, which I will tackle here by bringing in a novel perspective, the brain's intrinsic activity. C.

Intrinsic Network Activity in Human Brain Organoids

, 2021
Human brain organoids replicate much of the cellular diversity and developmental anatomy of the human brain. However, neurophysiology within organoids remains relatively under-explored. With high-density CMOS microelectrode arrays and shank electrodes, we probed broadband and three-dimensional activity of human brain organoids.

Exploration of intrinsic brain activity in migraine with and without comorbid depression [PDF]

The Journal of Headache and Pain, 2018
Major depressive disorder is a common comorbidity in migraineurs. Depression may affect the progression and prognosis of migraine. Few studies have examined the brain function in migraineurs that may cause this comorbidity. Here, we aimed to explore depression-related abnormalities in the intrinsic brain activity of interictal migraineurs with comorbid
