Disrupted functional connectivity affects resting state based language lateralization

open access: yesNeuroImage: Clinical, 2016
Pre-operative assessment of language localization and lateralization is critical to preserving brain function after lesion or epileptogenic tissue resection.

Perceived Time Shapes Physical Fatigue Accumulation and Its Neural Oscillatory Correlates

open access: yesAdvanced Science, EarlyView.
Can a clock change the course of physical fatigue? By covertly manipulating the clock calibration during repeated isometric contractions, we showed that perceived time shapes fatigue accumulation and frontal oscillatory dynamics. While fatigue accumulation was only reduced when the clock was slowed down, frontal oscillatory dynamics followed perceived ...

GEMReg: a spatio-temporal grayordinate ensemble modelling framework for predicting task activation maps from resting-state fMRI

open access: yesFrontiers in Neuroscience
ObjectiveRecent advances in neuroimaging have highlighted the growing utility of resting-state functional magnetic resonance imaging (rs-fMRI) as an alternative to task-based fMRI. In addition to being simpler, cost-effective, and time-efficient, rs-fMRI

The Relationship Between Cognition and Cerebrovascular Reactivity: Implications for Task-Based fMRI

open access: yesFrontiers in Physics, 2021
Elucidating the brain regions and networks associated with cognitive processes has been the mainstay of task-based fMRI, under the assumption that BOLD signals are uncompromised by vascular function.

Methodological problems in fMRI studies on acupuncture: a critical review with special emphasis on visual and auditory cortex activations [PDF]

open access: yes, 2011
Functional magnetic resonance imaging (fMRI) has been used for more than a decade to investigate possible supraspinal mechanisms of acupuncture stimulation. More than 60 studies and several review articles have been published on the topic.

A Gut‐Brain Axis Underlying Succinate‐Associated Compulsive‐Like Behavior

open access: yesAdvanced Science, EarlyView.
Gut‐derived succinate is associated with an excitatory‐inhibitory imbalance in dmPFC glutamatergic neurons, involving microglial SUCNR1 activation and vagal afferent signaling via upregulated gut 5‐HT4 receptors along the DVC‐CeA‐dmPFC circuit, changes that are linked to excessive compulsive‐like behavior.

dsGrid: a dual-site TMS grid-search method for personalized targeting of motor network connectivity

open access: yesBrain Stimulation
Background: Brain targets for transcranial magnetic stimulation (TMS) are often derived from anatomical landmarks or group-level neuroimaging data, which lack precision or personalization, contributing to the variability in TMS responses.

Scalable and Adaptive Spatiotemporal Modeling for Task-Based fMRI Analysis

open access: yes
Task-based fMRI is commonly analyzed using voxel-wise general linear models, a non-spatial scalable approach that can yield fragmented activation maps. Spatial alternatives such as kernel smoothing and Bayesian models address this but either blur activation boundaries or are computationally prohibitive at modern spatial resolutions. We introduce SPLASH

Temporal‐Targeted Accelerated 40 Hz tACS Enhances Cognitive Function and Network Integration in Alzheimer's Disease: A Randomized Clinical Trial

open access: yesAdvanced Science, EarlyView.
Bilateral temporal accelerated 40‐Hz tACS improves cognitive function in patients with Alzheimer's disease. Resting‐state fNIRS identifies treatment‐related increases in frontotemporoparietal functional connectivity, which are associated with cognitive improvement. ABSTRACT The temporal lobes are key hubs for memory and cognition.

The evaluation of DUNE: a U-Net-based neural network to denoise multi-echo fMRI data

open access: yesNeuroImage
Task based fMRI data suffers from scanner and physiologic noise. Consequently, finding the task based BOLD responses out of the noise is challenging.
