Hyperbolic Geometry as a Model of DMT Experiences

HN commenters point to it as an interesting lecture related to psychedelics, brain geometry and hyperbolic space, with a good intro to hyperbolic geometry.

Andres Gomez Emilsson of the Qualia Research Institute presents a model of DMT experiences using hyperbolic geometry and dynamical systems theory. He describes how different intoxication levels correspond to changing curvature and information content of experience.
