Well if DMT were neuro-toxic then serotnin would also be a neuro-toxin. Also you should consider that DMT is proven to be in our blood stream at trace levels and is believed to play a role in dreaming, meditation, NDE and birth. All the evidence Rick Strassman puts forth without a doubt proves that DMT play a vital role in our brain, it has jsut yet to be bonified.
The brain also has a barrier called the blood-brain barrier (BBB) that filters out toxic substance and thought some toxins fight there way through DMT doesnt. The brain actually goes out of its way to transport DMT across the barrier, it actively transports it. Amino acids, unlike dmt, have to fight to cross the barrier but the brain takes special liking to DMT (Rick Strassman M.D.). With the way the brain treats DMT with the MAO, Strassman specualtes that it is like brainfood for the brain because of how quickly it uses it up.
The pineal gland; The Pineal Gland is a gland directly in the center of the brain but is not actually in the brain and is under high guard. Previous scientists believe that the gland is jsut responsible for melatonin production but it would seem rather foolish to guard a gland that produces melatonin which such high security. The only way the pineal is subjected to stress is when a person is going through extreme high levels of stress that release certain chemicals (i forget the namea right now, im about to fall asleep) that can activate the pineal. The pineal gland also mysteriously has all the building blocks to create DMT. One of the most convincing piece of evidence is that the most abundant traces of DMT were found in the cerebral cortex, caudate putamen, and amygdaloid nuclei which is directly above the pineal gland which contains all the emotional pathways and serotonin, dopamine and trace-amine receptors.
