Neural Synchrony and Network Dynamics in Social Interaction: A Hyper-Brain Cell Assembly Hypothesis.

Area of Science:

• Neuroscience
• Social Interaction
• Computational Neuroscience

Background:

• Interpersonal interaction relies on neural communication within and between brains.
• Neuronal dynamics and network synchrony are key to understanding cell assembly formation.

Purpose of the Study:

• To propose the Hyper-Brain Cell Assembly Hypothesis.
• To explore how cell assemblies emerge within and between interacting brains.

Main Methods:

• Conceptual review of neural synchrony and network dynamics.
• Theoretical framework development for inter-brain cell assemblies.

Main Results:

• Cell assemblies can emerge not only within individual brains but also between interacting brains.
• A 'hyper-brain cell assembly' integrates oscillatory activity across brains, forming a common unit.
• Hyper-brain modules, comprising nodes across multiple brains, represent potential structures for these assemblies.

Conclusions:

• Neuronal dynamics during social interaction are brain-wide, involving coupled physiological systems.
• The Hyper-Brain Cell Assembly Hypothesis offers a new perspective on the neural basis of social behavior.
