[Human interaction, social cognition, and the superior temporal sulcus]

Area of Science:

• Neuroscience
• Cognitive Science
• Social Psychology

Context:

• Human social behavior relies on complex cognitive functions.
• Neuroimaging techniques like MRI are beginning to map the neural underpinnings of social cognition.
• The concept of the "social brain" encompasses the network of regions involved in social processing.

Purpose:

• To explore the neuroanatomical basis of human social cognition.
• To highlight the role of the superior temporal sulcus (STS) within the social brain network.
• To connect social cognitive functions like "theory of mind" and "meta-cognition" to neural substrates.

Summary:

• The superior temporal sulcus (STS) is identified as a core region of the social brain.
• Modeling studies in healthy individuals demonstrate the STS's involvement in recognizing biological beings, facial cues, eye gaze, intentionality, and emotions.
• Pathological studies, particularly in autism, corroborate the STS's critical function in social abilities and communication.

Impact:

• Understanding the social brain, particularly the STS, provides insights into the neurobiological basis of social interaction and empathy.
• This research contributes to understanding conditions with altered social abilities, such as autism.
• The findings support the conceptualization of "meta-cognition" as fundamental to human social organization and culture.
