The brain might function predominantly as an organ of prediction, shaping perceptions and actions based on anticipated information and prediction errors.
The growth in interest around predictive processing has been substantial, with a surge in published papers and general attention starting around 2010.
Neuromodulators like acetylcholine, noradrenaline, dopamine, and serotonin play key roles in determining the level of precision on how our brain processes sensory information, impacting perception and behavior.
