Intranasal Seletracetam in a Patient with Reading Epilepsy: First‐in‐Human Use to Prevent Reflex Seizures

Annals of Neurology, EarlyView.
We report the first human use of intranasal seletracetam (SEL) to prevent reflex seizures. A patient with epilepsy with reading‐induced seizures on levetiracetam (3,000 mg/day) continued to experience reading‐induced focal seizures with preserved consciousness.

Ten Key Insights into the Use of Spinal Cord fMRI

Brain Sciences, 2018
A comprehensive review of the literature-to-date on functional magnetic resonance imaging (fMRI) of the spinal cord is presented. Spinal fMRI has been shown, over more than two decades of work, to be a reliable tool for detecting neural activity.

A blind deconvolution approach to recover effective connectivity brain networks from resting state fMRI data

, 2012
A great improvement to the insight on brain function that we can get from fMRI data can come from effective connectivity analysis, in which the flow of information between even remote brain regions is inferred by the parameters of a predictive dynamical ...

Aberrant posterior cingulate connectivity classify first-episode schizophrenia from controls: A machine learning study

, 2020
Background Posterior cingulate cortex (PCC) is a key aspect of the default mode network (DMN). Aberrant PCC functional connectivity (FC) is implicated in schizophrenia, but the potential for PCC related changes as biological classifier of schizophrenia ...

Probabilistic Lesion Mapping to Optimize Thalamotomy Targets for Focal Hand Dystonia

Annals of Neurology, EarlyView.
Objective Focal hand dystonia (FHD) severely impairs task‐specific motor control, yet the optimal surgical target for stereotactic intervention remains uncertain. This study aimed to identify the precise thalamic lesion site associated with symptomatic improvement and to clarify its network connectivity. Methods We retrospectively analyzed 164 patients

Detecting language network alterations in mild cognitive impairment using task‐based fMRI and resting‐state fMRI: A comparative study

Brain and Behavior
Objective The objective of this study was to investigate the functional changes associated with mild cognitive impairment (MCI) using independent component analysis (ICA) with the word generation task functional magnetic resonance imaging (fMRI) and ...

Improving Reliability of Subject-Level Resting-State fMRI Parcellation with Shrinkage Estimators [PDF]

, 2015
A recent interest in resting state functional magnetic resonance imaging (rsfMRI) lies in subdividing the human brain into anatomically and functionally distinct regions of interest.

Tau Pathology in Alzheimer's Disease Uniquely Affects Sulcal Depths

Annals of Neurology, EarlyView.
Objective Though it is widely known that tau deposition affects brain structure, the precise localization of these effects is poorly understood, especially in relation to gyral and sulcal anatomy. We investigated whether tau pathology in Alzheimer's disease (AD) preferentially affects sulci, and particularly sulcal depths.

Neurovascular coupling in eye-open-eye-close task and resting state: Spectral correspondence between concurrent EEG and fMRI

NeuroImage
Neurovascular coupling serves as an essential neurophysiological mechanism in functional neuroimaging, which is generally presumed to be robust and invariant across different physiological states, encompassing both task engagement and resting state ...

Regression dynamic causal modeling for resting‐state fMRI

bioRxiv, 2020
“Resting-state” functional magnetic resonance imaging (rs-fMRI) is widely used to study brain connectivity. So far, researchers have been restricted to measures of functional connectivity that are computationally efficient but undirected, or to effective
