Summary
Bodily-contact communication devices significantly impact brain activity during conversations, reducing electroencephalogram (EEG) power for stress relief and enhancing communication complexity for sustained involvement.
Area of Science:
- Neuroscience
- Communication Studies
- Human-Computer Interaction
Background:
- Understanding the neurophysiological effects of novel communication methods is crucial.
- Bodily-contact communication offers a unique channel for interaction, potentially influencing cognitive states.
Purpose of the Study:
- To investigate the impact of a bodily-contact communication medium on brain activity during verbal communication.
- To analyze electroencephalogram (EEG) time series for changes in power and complexity.
Main Methods:
- Analysis of electroencephalogram (EEG) signals from human subjects during communication via a bodily-contact device.
- Application of permutation entropy (PE) and multiscale entropy (MSE) analyses to EEG data.
Main Results:
- Significant reduction in overall power of EEG signals, indicating stress relief and relaxation.
- Increased complexity in EEG time series, suggesting enhanced sustained involvement in communication.
Conclusions:
- Bodily-contact communication mediums can positively influence cognitive and emotional states.
- Potential applications include complementary therapies for developmental disorders, attention enhancement, and long-distance intimate interactions.

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

01:19Contact-dependent Signaling
47.6K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

3.3K
Neurons, the fundamental units of the brain and nervous system, function as the primary transmitters of information throughout the body. Their ability to communicate through electrical and chemical signals is vital for every bodily function, from regulating the heartbeat to processing complex thoughts. Each neuron has three main components: the cell body (soma), dendrites, and an axon, each specialized to facilitate swift and efficient neural communication.

Effective communication is the foundation of a good organization. Communication is the lifeblood of an organization that connects the group with messages. In an organization, communication occurs in upward, downward, and horizontal lines. Downward communication travels from the administrative and senior levels to the staff through official channels such as manuals, rules and regulations, and organizational charts. Staff members initiate upward communication, which is addressed to executives and...

01:21Pilot and Numeric Relaying
492
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:
