Association Areas of the Cortex

5.7K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

229
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Summary

Problematic Internet use (PIU) and excessive smartphone use (ESU) impair emotional face expression recognition by affecting social brain networks. These findings suggest the social brain network plays a key role in PIU and ESU.

Area of Science:

  • Neuroscience
  • Psychology
  • Digital Health

Background:

  • Problematic Internet use (PIU) and excessive smartphone use (ESU) are linked to disruptions in functional brain networks.
  • The impact of PIU and ESU on emotional face expression (EFE) recognition remains unclear, despite evidence suggesting impairment in similar addiction contexts.

Purpose of the Study:

  • To investigate the effects of PIU and ESU on EFE recognition.
  • To explore the functional brain changes associated with EFE recognition in individuals with PIU and ESU.

Main Methods:

  • Utilized the Facial Emotion Recognition Paradigm to assess cortico-limbic responses during EFE recognition.
  • Employed combined functional Magnetic Resonance Imaging (fMRI) and psychophysiological analysis to measure EFE-related brain activity.
  • Assessed PIU and ESU levels using self-reported questionnaires.

Main Results:

  • Found positive associations between the severity of PIU and ESU and functional connectivity within networks related to emotional cognitive control and social cognition.
  • Demonstrated that PIU and ESU are linked to alterations in the brain's social network functioning, particularly impacting EFE recognition.

Conclusions:

  • Highlight the significant involvement of social functioning, specifically EFE recognition, in the context of PIU and ESU.
  • Suggest that the social brain network, in addition to executive and reward systems, may be critically implicated in the pathogenesis of PIU and ESU.
