[Development and neural basis of social behavior]

Area of Science:

• Neuroscience
• Ethology
• Developmental Psychology

Context:

• Social isolation in early development affects social communication.
• The Bouquet method analyzes social communication behavior to assess emotional states.
• Studies on domestic chicks and common marmosets investigate the impact of isolation.

Purpose:

• To develop a multivariate analysis (Bouquet method) for discriminating emotional states in social interactions.
• To investigate the effects of social isolation on communication behavior development in chicks and marmosets.
• To explore potential interventions for improving social affiliation in isolated animals and children with Asperger syndrome.

Summary:

• Social isolation during a sensitive period leads to reduced affiliated behavior and observable neuronal differences (amygdala, mesolimbic area, gene expression) in chicks.
• Post-sensitive period interventions with SSRI/SNRI or Ubiquinol combined with social interaction improved social affiliation in isolated chicks.
• The Bouquet method successfully discriminated between children with Asperger syndrome and typically developed siblings during clinical interviews.

Impact:

• Identifies a critical sensitive period for social interaction crucial for normal behavioral development.
• Provides potential therapeutic targets (SSRI/SNRI, Ubiquinol) for mitigating effects of social isolation.
• Demonstrates the Bouquet method's utility in differentiating social communication patterns in neurodevelopmental conditions like Asperger syndrome.
