The default mode network and social understanding of others: what do brain connectivity studies tell us
[2023-03-23 21:26:22]
Human interprets stimuli based on possible social relevance, participates in activities such as thinking about myself and others, exchanging these ideas, etc., to make social relationships and positions of themselves and others It is a social animal that tends to spend a long time to evaluate. Throughout life (Schilbach et al., 2008). Dunbar and colleagues proposed a "social brain hypothesis" that the brains seen in primates reflect the computational necessity of a complex social system that constitutes its member order (Dunbar, 1993) .
Over the past two decades, human social brain has been found to be one of several (1) understanding others, (2) understanding ourselves, (3) controlling ourselves, and (4) It has been extensively studied in different fields. Process self and others (Lieberman, 2007). However, in the most strict sense, social cognition means understanding others such as emotional, psychological, psychological state, behavior, etc. (Lieberman, 2007). More and more research is being conducted in the task of requiring participants to understand and interact with others, such as recognition and interpretation of the emotional state of others, expression of sympathy for others, inference of others, the default mode It shows that the area of network (DMN) is activated massively Faith and intention to others' behavior and moral judgment of performance (Schilbach et al., 2008; Laird et al., 2011). In addition to duplication with DMN, the large brain network of the social domain also contains several areas outside the DMN. As these social behaviors usually involve a wide range of cognitive processes such as acquiring, searching and processing related lives, relationships and mental conditions. information. Other (Mars et al., 2012)
In this article we will use the brain connection method to investigate the results related to DMN in the field of social understanding of others. Summarize some important areas of social behavior, emotional perception, empathy, empathy, mind theory (ToM or psychology) and ethics for healthy subjects and patients with autism, psychosis and schizophrenia (see table ). 1). Existing results are organized through two aspects. One is how the areas within the DMN interact when people perform these social tasks and the other is the other distributed brain system where DMN contributes to the social cognition process of others It is a way to interact. Discuss the last possible future direction
A promising new field of research is based on a brain network responsible for understanding the minds of recently discovered others. It is called the default mode network (as it performs other tasks and is performed most of the time when waking up), it involves clustering in several different regions of the cerebral cortex. Initial research on the function of this network in psychiatric patients is under way, and as expected, there is a problem. In addition to "abnormal functional connectivity" between the various parts of the network, various studies have noticed that the number of important areas of the network is decreasing.
Research continues to examine the theory of poor connectivity between different parts of the brain and between different communication paths, mainly between so-called "default mode networks" (DMN). The functional barriers of the network impede the performance and effort to participate in the activities. ADHD can be diagnosed through extensive interview procedures, behavior and symptom assessment skills, third-party observations, and comprehensive medical history. Comprehensive neuropsychological and psychological education tests have many advantages, but they are not necessary for diagnosis. Neuropsychological examination helps you to understand the inside and outside of your own brain features, suitable for learning ADHD and living well after diagnosis.
I like to call them "Big Three" brain network - default mode network, prominent network with control network implementati
