Applied Imagination: Imagine the Good, and Change Your Life for the Better
Key Takeaways (Executive Summary):
- The brain learns from imagined experiences exactly the same way it does from real ones.
- Vivid positive imagination activates the Ventral Striatum, calculating reward prediction errors similarly to real-world pleasure.
- The striatum works in conjunction with the dorsomedial prefrontal cortex (dmPFC) to update social models and expectations.
- Imagining interactions can lead to genuine changes in sympathy and attitude toward the imagined people.
A joint study by cognitive neurobiologists from the University of Colorado Boulder and the Max Planck Institute has provided strong evidence that vivid imagination physically rewires the brain using the exact same algorithms as real experience.
What the Scientists Did
A team of cognitive neurobiologists led by Roland Benoit (University of Colorado Boulder) and Aroma Dabas (Max Planck Institute) took 50 volunteers and placed them in an fMRI scanner.
They were asked to close their eyes and intensely imagine detailed scenarios of interacting with specific people (both positive and negative).
What the fMRI Scanner Recorded
The scans revealed the actual mechanism of how imagination reprograms the brain:
- Activation of the Ventral Striatum: This area is the main element of the reward system, responsible for calculating the so-called reward prediction error.
- When people imagined a vivid positive scenario, the ventral striatum "lit up" as if they were receiving pleasure in the real world.
- Connection with the Prefrontal Cortex: The striatum worked in tight conjunction with the dorsomedial prefrontal cortex (dmPFC).
- The dmPFC is responsible for storing long-term memory and social models.
Result: The brain physically updated the system's expectations. After the test, participants began to experience real sympathy and a changed attitude toward the people with whom they had simply imagined contact.
The main conclusion of the study's authors: "The brain learns from imagined experience exactly the same way it does from a real one."
