Topic of the Month: Science of Emotions

• Focus on understanding emotions and related tools.
• Previously discussed stress, resilience, and motivation.
• All episodes now captioned in English and Spanish.
• New resources available, including a YouTube video for NSDR (Non-Sleep Deep Rest).

Understanding Emotions

• Emotions are subjective and vary for each individual.
• Perception of emotions is influenced by personal experiences and biological factors.
• No single brain area governs emotions; they arise from complex brain-body interactions.
• Important concepts:
  • Interoception: Awareness of internal body states.
  • Exteroception: Awareness of external stimuli.
• Emotions are built from infancy through childhood and adolescence.

Developmental Aspects

• Infants initially lack understanding of the world; feelings of anxiety drive interaction.
• Caregiver responses to an infant's needs shape emotional development.
• Attachment theory (Bowlby & Ainsworth):
  • A Babies: Secure attachment; happy upon caregiver's return.
  • B Babies: Avoidant attachment; less likely to seek comfort.
  • C Babies: Ambivalent attachment; show annoyance upon return.
  • D Babies: Disorganized attachment; lack consistent response.

The Role of Hormones and Circuits

• Hormones like dopamine and oxytocin play key roles in emotional experiences and connections.
• Puberty triggers hormonal changes affecting emotional bonding and social interactions.
• Kisspeptin: Key hormone in triggering puberty.
• Oxytocin: Promotes social bonding; enhances empathy and emotional awareness.
• Vasopressin: Involved in pair bonding; influences monogamous behavior.

Brain Mechanisms

• The brain's right and left hemispheres contribute differently to emotional experiences:
  • Left Brain: Language, logic, and analytical functions.
  • Right Brain: Visual-spatial tasks and emotional processing, though not strictly emotive.
• Vagus nerve stimulation can influence emotional states, but often increases alertness rather than calmness.

Practical Tools for Emotional Understanding

• Mood Meter App: Helps identify and predict emotional states.
• Focus on three axes of emotions:
  • Alertness: Level of calm vs. excitement.
  • Valence: Good vs. bad feelings.
  • Interoception vs. Exteroception: Internal vs. external focus.

Final Thoughts

• Reflecting on emotional experiences through the lens of interoception and exteroception can enhance emotional intelligence.
• Future discussions will include psychedelics and their impact on emotional states.
