Core Concepts
Subcortical regions predict alpha-band modulation during spatial attention tasks.
Abstract
Subcortical structures influence alpha oscillations during spatial attention tasks.
Thalamus, caudate nucleus, and globus pallidus predict alpha-band modulations.
Different subcortical structures contribute variably under different perceptual load conditions.
Structural changes in subcortical regions may reflect neurological disorders.
MEG and MRI data were combined to investigate the relationship between subcortical volumes and alpha oscillations.
Hemispheric lateralization of thalamus, caudate nucleus, and globus pallidus correlated with alpha power modulation.
Thalamus was associated with easier task conditions, while globus pallidus and caudate nucleus were linked to more challenging conditions.
The study provides insights into the role of subcortical structures in modulating oscillatory activity during spatial attention tasks.
Abstract:
Subcortical regions play a role in high-level cognitive functions like spatial attention.
Little is known about how subcortical regions contribute to posterior alpha band oscillations under varying cognitive challenges.
Introduction:
Brain amplifies goal-relevant inputs and suppresses non-relevant inputs through selective attention.
Neocortex plays a significant role in spatial attention, but contributions of subcortical regions are less understood.
Data Extraction:
"Thalamus (mean ± std = -0.0123 ± 0.0121, p-value < 0.000), putamen (mean ± std = -0.0149 ± 0.0285, p-value = 0.004) and nucleus accumbens (mean ± std = -0.1141 ± 0.0746, p-value < 0.000) have significantly negative LV values."
"The winning model constituted of thalamus, caudate nucleus and globus pallidus."
