Age-Related Attenuation of Dominant Hand Superiority [PDF]

, 2006
The decline of motor performance of the human hand-arm system with age is well-documented. While dominant hand performance is superior to that of the non-dominant hand in young individuals, little is known of possible age-related changes in hand ...

Functional Parcellation of the Lateral Mesencephalus [PDF]

Journal of Neuroscience, 2012
The mesencephalic locomotor region (MLR), which includes the pedunculopontine nucleus (PPN) and the cuneiform nucleus (CN), has been recently identified as a key structure for locomotion and gait control in mammals. However, the function and the precise anatomy of the MLR remain unclear in humans.

Function lateralization via measuring coherence laterality [PDF]

NeuroImage, 2009
A data-driven approach for lateralization of brain function based on the spatial coherence difference of functional MRI (fMRI) data in homologous regions-of-interest (ROI) in each hemisphere is proposed. The utility of using coherence laterality (CL) to determine function laterality was assessed first by examining motor laterality using normal subjects'

Lateral interactions at functional monolayers [PDF]

J. Mater. Chem., 2011
This review gives an overview of the recent literature regarding lateral molecular interactions in monolayers. The first part (Section 3) focuses on systems of self-assembled monolayers on metal surfaces, discussing the covalent and noncovalent interactions of the terminal functionality or between the molecular chains of the molecules. The second part (

Lateral masking as a function of spacing [PDF]

Perception & Psychophysics, 1983
It is argued that lateral masking is a composite of several processes. These processes include response competition, distribution of attention, perceptual grouping, and feature (contour) interaction. Three experiments were carried out in an attempt to isolate some of the components.

Gender and Rapid Alterations of Hemispheric Dominance during Planning [PDF]

, 2012
Background: Mental planning and carrying out a plan provoke specific cerebral hemodynamic responses. Gender aspects of hemispheric laterality using rapid cerebral hemodynamics have not been reported.

Laterality in Children: Evidence for Task-Dependent Lateralization of Motor Functions [PDF]

International Journal of Environmental Research and Public Health, 2020
The behavioral preference for the use of one side of the body starts from pre-natal life and prompt humans to develop motor asymmetries. The type of motor task completed influences those functional asymmetries. However, there is no real consensus on the occurrence of handedness during developmental ages.

The effects of hemodynamic lag on functional connectivity and behavior after stroke [PDF]

, 2015
Stroke disrupts the brain's vascular supply, not only within but also outside areas of infarction. We investigated temporal delays (lag) in resting state functional magnetic resonance imaging signals in 130 stroke patients scanned two weeks, three months

Using a novel source-localized phase regressor technique for evaluation of the vascular contribution to semantic category area localization in BOLD fMRI. [PDF]

, 2015
Numerous studies have shown that gradient-echo blood oxygen level dependent (BOLD) fMRI is biased toward large draining veins. However, the impact of this large vein bias on the localization and characterization of semantic category areas has not been ...
