Summary
Cognitive-motor dual-task training, like Verbal Working Memory-Balance (VWM-B), improves cognitive and motor functions in children with developmental dyslexia (DD). This approach enhances literacy by shifting cognitive resources, unlike single-task training.
Area of Science:
- Neuroscience
- Developmental Psychology
- Cognitive Science
Background:
- Developmental dyslexia (DD) requires innovative interventions.
- Cognitive-motor training shows promise for improving literacy in children with DD.
- Verbal Working Memory-Balance (VWM-B) is a novel program with demonstrated benefits for DD.
Purpose of the Study:
- To explore the neural mechanisms of VWM-B using functional connectivity (FC) analysis.
- To investigate how VWM-B impacts brain activity in children with DD.
Main Methods:
- A quasi-double-blind randomized clinical trial was conducted.
- Resting-state fMRI data were collected from 16 children with DD.
- Participants underwent 15 VWM-B training sessions over 5 weeks, with pre- and post-intervention measurements.
Main Results:
- Significant FC changes were observed in the postcentral gyrus, precuneus, superior frontal gyrus, and supramarginal/angular gyri.
- Decreased FC in postcentral gyri suggests increased automation of motor tasks.
- Increased FC in other areas indicates a shift of cognitive resources towards VWM-B related functions.
Conclusions:
- Cognitive-motor dual-task training is more effective than single-task training for children with DD.
- VWM-B training enhances cognitive and motor functions by improving postural control and automaticity.
- The findings underscore the importance of integrated cognitive and motor approaches for dyslexia interventions.

01:17Functions of Connective Tissues
16.4K
Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.

02:18Intrinsically Disordered Proteins
19.4K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

01:25Network Function of a Circuit

Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

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,...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
