Dennis McKenna - Is DMT A Neurotransmitter For The Gaian Brain?

The possible functions of endogenous DMT as a neurotransmitter or regulatory neurohormone in mammalian physiology are incompletely understood, and a matter of controversy. Its ubiquity in nature, however, suggests it may function at the biospheric level as a messenger molecule. The planetary ecosystem – sometimes romantically likened to Gaia, the feminine Mother of all life in Greek mythology – is a complex homeostatic system that is regulated and stabilised by complex feedback loops and symbiosis. These processes operate via signal transduction, the exchange of information mediated by molecular messengers. Neurotransmitters are one of many kinds of signal-transducing molecules in the body, but in ecosystems, photosynthetic plants produce a vast array of secondary products that mediate their interactions with virtually all organisms in the environment, including humans. In this talk I will suggest that DMT and the ‘family’ of related tryptamines – may specifically target the big-brained primates to trigger cognitive evolution.
