Head Trauma as a Precipitating Factor for Late-onset Leigh Syndrome: a Case Report

open access: yesEmergency, 2016
Leigh syndrome is a severe progressive neurodegenerative disorder with different clinical presentationsthat usually becomes apparent in the first year of life and rarely in late childhood and elderly years.

Attention maps in the brain [PDF]

open access: yesWIREs Cognitive Science, 2013
AbstractOver 20 distinct cerebral cortical areas contain spatial map representations of the visual field. These retinotopic, or visuotopic, cortical areas occur not only in the occipital lobe but also in the parietal, temporal, and frontal lobes.

Low-dimensional morphospace of topological motifs in human fMRI brain networks [PDF]

open access: yesNetwork Neuroscience, 2018
We present a low-dimensional morphospace of fMRI brain networks, where axes are defined in a data-driven manner based on the network motifs. The morphospace allows us to identify the key variations in healthy fMRI networks in terms of their underlying ...

White matter microstructural perturbations after total sleep deprivation in depression

open access: yesFrontiers in Psychiatry, 2023
BackgroundTotal sleep deprivation (TSD) transiently reverses depressive symptoms in a majority of patients with depression. How TSD modulates diffusion tensor imaging (DTI) measures of white matter (WM) microstructure, which may be linked with TSD’s ...

Adaptive Gaussian Markov Random Fields with Applications in Human Brain Mapping [PDF]

open access: yes, 2005
Functional magnetic resonance imaging (fMRI) has become the standard technology in human brain mapping. Analyses of the massive spatio-temporal fMRI data sets often focus on parametric or nonparametric modeling of the temporal component, while spatial ...

Neuroplasticity in visual impairments

open access: yesNeurology International, 2018
The visual acuity loss enables the brain to access new pathways in the quest to overcome the visual limitation and this is wellknown as neuroplasticity which have mechanisms to cortical reorganization.

Mapping Brain Activity During Loss of Situation Awareness: an EEG investigation of a basis for top-down influence on perception [PDF]

open access: yes, 2014
Objective: The objective was to map brain activity during early intervals in loss of Situation Awareness (SA) to examine any co-activity in visual and high-order regions, reflecting grounds for top-down influences on level 1 SA.
