Physical changes included an increases in blood pressure, in the amplitude of the patellar reflex, and in pupillary diameter. The subjective changes are not unlike those seen with small doses of LSD. A point-by-point comparison between the tryptamine and LSD syndromes reveals a close similarity which is consistent with the hypothesis that tryptamine and LSD have a common mode of action."

For instance, clorgyline and deprenyl increased brain levels of 5-HT 8.5-fold and 4.4-fold and of 5-MT 20-fold and 5-fold, respectively.

[...] Tryptamine, but not DMT, increases locomotor activity in the mouse, while both antagonize reserpine depression (V ANE et al., 1961). [...] In the rat, tryptamine causes backward locomotion, Straub tail, bradypnea and dyspnea, and clonic convulsions (TEDESCHI et al., 1959). [...] Tryptamine produces a variety of changes in the cat causing signs of sympathetic activation including mydriasis, retraction of nictitating membrane, piloerection, motor signs such as extension of limbs and convulsions and affective changes such as hissing and snarling (LAIDLAW, 1912).
