Brain connectivity and visual attention.

open access: yes, 2023
Emerging hypotheses suggest that efficient cognitive functioning requires the integration of separate, but interconnected cortical networks in the brain. Although task-related measures of brain activity suggest that a frontoparietal network is associated

Connectivity and Equity in the Americas Program Initiative final report 2006-2009 [PDF]

open access: yes, 2010
The Connectivity and Equity in the Americas (CEA) program supports research on the use of Information and Communication Technologies (ICTs) as a means to foster sustainable development in Latin America and the Caribbean (LAC). Since the inception of CEA (

Dynamic BOLD functional connectivity in humans and its electrophysiological correlates [PDF]

open access: yes, 2012
Neural oscillations subserve many human perceptual and cognitive operations. Accordingly, brain functional connectivity is not static in time, but fluctuates dynamically following the synchronization and desynchronization of neural populations.

Better than Rician: modelling millimetre wave channels as two-wave with diffuse power

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
This contribution provides experimental evidence for the two-wave with diffuse power (TWDP) fading model. We have conducted two indoor millimetre wave measurement campaigns with directive horn antennas at both link ends.

The architecture of functional lateralisation and its relationship to callosal connectivity in the human brain

open access: yesNature Communications, 2019
Many functions of the human brain are lateralised i.e. associated more strongly with either the left or the right hemisphere of the brain. Here, the authors report the first complete map of functional asymmetries in the human brain, and its relationship ...

PARCELLATION OF THE CINGULATE CORTEX AT REST AND DURING TASKS: A META-ANALYTIC CLUSTERING AND EXPERIMENTAL STUDY

open access: yesFrontiers in Human Neuroscience, 2013
Anatomical, morphological and histological data have consistently shown that the cingulate cortex can be divided into four main regions. However, less is known about parcellations of the cingulate cortex when involved in active tasks.

Differential Patterns of Connectivity in Progressive Mild Cognitive Impairment

open access: yes, 2012
It is now widely accepted that Alzheimer's disease is characterized by a functional disconnection between brain regions. The disease appears to begin up to decades prior to clinical diagnosis.
