Episode notes
Brain Mimics Laughter Automatically
- Laughter triggers brain regions that mirror others’ smiles and laughs via the premotor cortex.
- This neurological mirroring causes laughter to spread contagiously in social groups.
Mirror Neurons Drive Contagious Laughter
- Mirror neurons activate facial muscles responsible for smiling when we see others laugh.
- This happens even if we are not laughing ourselves, making laughter contagious.
Nervous Laughter Relieves Stress
- Nervous laughter occurs because the brain uses laughter to release feel-good endorphins under stress.
- This response can happen in inappropriate moments like presentations or sad events.
