The mind, explained is a show on Netflix. I watched the miniseries recently. They cover some very cool functions of the brain and how they work, including psychedelics. I suggest checking it out. In the psychedelics episode, they gave an analogy of how they work on the neural pathways. Imagine your brain as a snow covered hill. As you travel across the hill you leave a path in the snow. As more travel occurs, main paths begin to form as it becomes packed down, and it’s harder to get out of those trails. Psychedelics is a fresh snow storm that fills in those trails allowing for new directions and paths of travel. It had a neat visual to go with it. Happy travels!
