In their study, the researchers measured brain activity during the first 20 seconds of each hand-over-hand handshake, or "bungee." Their analysis revealed that these changes were more pronounced in the posterior cingulate cortex, where the brain is associated with impulse control and impulse control—which is also associated with an increase in brain activity. The authors note, however, that this effect does not seem to have been directly correlated with performance on test-swords or even with the amount of time the subjects had to perform for each movement.

The authors theorized that the brain is responding to a stimulus with an increased capacity to encode it, as well as a decrease in the amount of the signal we are actually experiencing. (A more accurate interpretation would be that the brain is responding to the stimulus without the ability to generate a corresponding response, suggesting that the amount of information in the brain's signal processing circuitry is actually just the amount of information our brain could generate at a very early stage.)

The authors also claim that this change in brain activity does not affect their understanding of the brain's capacity to process or interpret information. "For example, the ability to interpret visual and auditory information in a different way than before has been assessed with the help of a new brain imaging technique that can map the brain's electrical activity to individual brain areas," they say. The work adds to a growing body of evidence that the ability to process and interpret information in the human brain has not been directly linked to performance on tests.

The authors suggest that this new, more accurate ability is also likely to have an influence on how we think about and evaluate the world. "Our understanding of our world is based on the basic human understanding of the world, and so we need to use it more carefully," says Kornhuber. "By using this new technique, we are making progress towards better understanding of the human brain and more effective decision making processes."
