What Big Data Says About Psychedelics

Interesting article.  Mind-altering substances, medical treatments, and big data.

Scientists are aiming artificial intelligence at the puzzle that is our brains.

  • Research using natural-language processing tools in machine learning is helping us understand conscious awareness and how drugs alter it.
  • Mental health conditions may be the price we humans pay for the huge evolutionary advantage of having a default mode network.
  • Psychedelics may work by lifting the filters of sensory input essential to DMN processes.

The default mode network - 

The brain’s default mode network (DMN)—a system we’ve begun to identify and investigate only in the 21st century—seems to be extremely relevant to how drugs work. The DMN is our brain’s deepest neural processing layer. When we’re not in a task-focused mind state (for example, when we’re staring out of the window instead of reading), this brain network is active.
