Summary
Online mind-body training (MBT) significantly reduced anxiety and anger by strengthening default mode network (DMN) connectivity in healthcare providers. This study highlights MBT
Area of Science:
- Neuroscience
- Psychology
- Medical Science
Background:
- Online mind-body training (MBT) programs enhance psychological well-being.
- Neural mechanisms of meditation's therapeutic effects are under investigation.
- Changes in electroencephalographic (EEG) functional connectivity during MBT are not well understood.
Purpose of the Study:
- To investigate how an online MBT program alters EEG functional connectivity within the default mode network (DMN).
Main Methods:
- A 4-week online MBT program intervention was compared to a 4-week waiting control group.
- EEG data and psychological states were assessed at baseline and after 4 weeks.
- Functional connectivity within the DMN was analyzed across different frequency bands (theta, alpha, beta, delta).
Main Results:
- The MBT group showed significant reductions in anxiety and trait anger.
- Increased global DMN network strengths in the theta and alpha frequency bands were observed in the MBT group.
- These EEG connectivity changes were not observed in the control group, and other psychological variables remained unchanged.
Conclusions:
- Practicing online MBT is associated with functional network changes in the DMN.
- These findings suggest MBT may modulate neural networks involved in stress and anxiety responses.
- Online MBT demonstrates potential relevance for managing psychological distress through neurophysiological alterations.

01:06Virtual Work for a System of Connected Rigid Bodies
755
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.

01:17Functions of Connective Tissues
16.7K
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.

01:25Network Function of a Circuit
704
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.

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,...

01:07What is a Mode?
26.0K
The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set.
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...

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...
