Episode notes
Target PFC To Reduce Rumination
- Target dorsolateral prefrontal cortex processes to reduce rumination in depression, for example with therapies or neuromodulation.
- Improve PFC control to interrupt repetitive negative thoughts and enhance regulation.
Vulnerability Is Gene–Environment–Epigenetics
- Vulnerability to psychiatric illness arises from gene-by-environment interactions shaped by epigenetic regulation across development.
- Depression and anxiety reflect entwined genetic, developmental, social, and cultural influences rather than pure genetics.
Maasai Example Shows Context Matters
- Sapolsky recounts a Maasai woman who killed a goat and ripped it open, illustrating cultural norms shaping what counts as psychosis.
- He emphasizes that voices or behaviors can be normal in context but abnormal at the wrong time or setting.
