Discovering academics' key learning connections: An ego-centric network approach to analysing learning about teaching [PDF]

, 2014
The aim of this exploratory study is to investigate the role of personal networks in supporting academics’ professional learning about teaching. As part of a wider project, the paper focuses on the composition of academics’ networks and possible ...

Close or connected: Distance and connectivity effects on transport in networks [PDF]

Physical Review E, 2011
We develop an analytical approach which provides the dependence of the mean first-passage time (MFPT) for random walks on complex networks both on the target connectivity and on the source-target distance. Our approach puts forward two strongly different behaviors depending on the type - compact or non compact - of the random walk.

The Relationship Between Inflammation and Central Nervous System in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Aim Multiple sclerosis is an autoimmune demyelination disease that is seen especially in the young population and has a progressive course, causing motor, sensory, and cognitive deficits. In the literature, the pathogenesis of MS disease and the interconnection between the immune and central nervous system in the disease have not been fully ...

Structural and effective connectivity in focal epilepsy

NeuroImage: Clinical, 2018
Patients with medically-refractory focal epilepsy may be candidates for neurosurgery and some may require placement of intracranial EEG electrodes to localise seizure onset.

Predicting Motor Imagery Performance From Resting-State EEG Using Dynamic Causal Modeling

Frontiers in Human Neuroscience, 2020
Motor imagery-based brain–computer interfaces (MI-BCIs) send commands to a computer using the brain activity registered when a subject imagines—but does not perform—a given movement.

Visual binding, reentry, and neuronal synchrony in a physically situated brain-based device [PDF]

, 2003
By constructing and analyzing a physically situated brain-based device (i.e. a device with sensors and actuators whose behavior is guided by a simulated nervous system), we show that reentrant connectivity and dynamic synchronization can provide an ...

Determination of effective brain connectivity from functional connectivity with application to resting state connectivities [PDF]

Physical Review E, 2014
Neural field theory insights are used to derive effective brain connectivity matrices from the functional connectivity matrix defined by activity covariances. The symmetric case is exactly solved for a resting state system driven by white noise, in which strengths of connections, often termed effective connectivities, are inferred from functional data;

Network Localization of Fatigue in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Fatigue is among the most common symptoms and one of the main factors determining the quality of life in multiple sclerosis (MS). However, the neurobiological mechanisms underlying fatigue are not fully understood. Here we studied lesion locations and their connections in individuals with MS, aiming to identify brain networks ...

Changes in effective connectivity by propofol sedation.

PLoS ONE, 2013
Mechanisms of propofol-induced loss of consciousness remain poorly understood. Recent fMRI studies have shown decreases in functional connectivity during unconsciousness induced by this anesthetic agent.

Human brain distinctiveness based on EEG spectral coherence connectivity

, 2014
The use of EEG biometrics, for the purpose of automatic people recognition, has received increasing attention in the recent years. Most of current analysis rely on the extraction of features characterizing the activity of single brain regions, like power-
