PLEASURE GENERATORS in the Brain: The Neuroscience of Pleasure Explained
In the brain, pleasure is generated by a handful of brain regions called, “hedonic hotspots.” If you were to stimulate these regions directly, you would likely feel pleasurable sensations. However, not all of the hedonic hotspots are the same–some generate the raw sensations of pleasure whereas others are responsible for consciously interpreting and elaborating on the raw pleasure produced by the other hotspots. In this video, in addition to exploring the neuroscience of pleasure, we’ll see how understanding pleasure, happiness, meaning, and purpose can help us live better lives.
