Summary
Bilateral eye movements altered brain activity, particularly theta power in inconsistent-handed individuals. Maintaining posterior delta coherence may be key for sustained attention, highlighting individual differences in brain plasticity.
Area of Science:
- Neuroscience
- Cognitive Psychology
Background:
- Brain activity changes with different cognitive tasks.
- Electroencephalography (EEG) measures electrical activity in the brain.
Purpose of the Study:
- To investigate how bilateral eye movements affect resting-state brain activity.
- To examine differences in brain activity changes based on handedness and experimental condition.
Main Methods:
- Participants underwent EEG recordings before and after performing bilateral eye movements or a control task.
- Changes in absolute power and coherence across different frequency bands (delta, theta, beta) were analyzed.
- Differences in change scores between conditions and handedness groups were assessed.
Main Results:
- Inconsistent-handed participants showed a greater increase in theta and beta EEG power compared to consistent-handed participants.
- This increase in theta power was specific to the bilateral eye-movement condition for inconsistent-handers.
- A significant decrease in posterior delta coherence was observed in the control condition, while it was maintained in the eye-movement condition.
Conclusions:
- Bilateral eye movements can modulate brain activity, with effects varying by handedness.
- Maintenance of posterior delta coherence might be crucial for sustained attention.
- Individual differences, such as handedness, influence the brain's response to behavioral interventions.

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

01:43The Movement of Organelles and Vesicles
6.6K
In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...

01:18Fluid Movement Between Compartments
4.2K
The force applied by fluids against a surface, known as hydrostatic pressure, initiates the transfer of fluid among different compartments. Within our blood vessels, the blood's hydrostatic pressure is a result of the heart's pumping action. At the arteriolar end of capillaries, hydrostatic pressure (capillary blood pressure) exceeds the opposing colloid osmotic pressure created primarily by plasma proteins like albumin. This discrepancy in pressure propels plasma and nutrients from the...

Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
The simplest type of movement joints, working joints, are...

15.3K
Connective tissues are one of the four main tissue types in humans that are extensively present in the body. They are characterized by cells embedded in an extracellular matrix (ECM) composed of a ground substance and three main types of protein fibers— collagen, elastic, and reticular fibers. The ground substance of connective tissues can range from a watery and jelly-like consistency to mineralized and hard. The wide variety of cells in the connective tissues include fibroblasts,...
