• Sleep: How sleep shapes our memories, emotions and mental wellness, and how to manipulate memory and emotion during sleep?
• Memory: How memories are acquired, updated, corrected, and retrieved, and how unwelcome memories can be controlled and forgotten?
• Social Learning: How we know about ourselves, how we acquire likes and dislikes, and how we learn from others?
