Summary
This study reveals distinct brain activity patterns for alerting, orienting, and inhibition in school-aged children using EEG. These attention network components show unique brain source activations, differing from adult studies.
Area of Science:
- Neuroscience
- Developmental Psychology
- Cognitive Science
Background:
- Attention comprises three key functions: alerting, orienting, and inhibition.
- Understanding these attention sub-components in children is crucial for developmental neuroscience.
- Previous research often relied on adult fMRI, potentially missing developmental nuances.
Purpose of the Study:
- To investigate the neural correlates of alerting, orienting, and inhibition in typically developing school-aged children.
- To compare EEG-based event-related potentials (ERPs) and neuronal source activations with adult findings.
- To elucidate the distinct brain processes underlying attention sub-components during development.
Main Methods:
- Utilized the Attention Network Test (ANT) with 83 children aged 12-13 years.
- Recorded electroencephalography (EEG) using 128 electrodes.
- Analyzed reaction times (RTs), ERP amplitudes (N1, P3), and neuronal source activations.
Main Results:
- Significant effects of alerting, orienting, and inhibition on RTs were observed.
- Alerting and orienting correlated with increased N1 amplitude.
- Inhibition correlated with increased P3 amplitude.
- Neuronal source analysis revealed distinct brain regions for each attention sub-component, differing from adult fMRI studies.
Conclusions:
- The study successfully differentiated the neural underpinnings of attention sub-components in children using EEG.
- Neuronal source activations for attention processes in children show developmental specificity.
- EEG-based source analysis provides insights into attention network development not apparent from scalp data alone.

01:30Attention-Deficit/Hyperactivity Disorder
896
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

02:26Protein Networks
4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:30Typical Model Studies
632
Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

02:18Network Covalent Solids
16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:21Antipsychotic Drugs: Typical and Atypical Agents
839
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...
