Emotion: The Brain’s Most Human Signal

An exploration of how the brain generates the rich inner world we call emotion. This episode separates feeling from expression, looks at how scientists decode something animals can’t verbalize, and traces the shift from old “emotion centers” to modern network-based models. From lesion studies to human imaging, we follow the evidence that shapes affective neuroscience—and why emotions remain both scientifically elusive and deeply defining to our species.
