In a study of eight healthy volunteers, the [5-HT.sub.1A/2A] agonist psilocybin from Psilocybe mushrooms was found to selectively impair attentional tracking but not spatial working memory performance (26).
Furthermore, Moreira-Neto (2013), basidiomycetes fungi from the genera of Trametes, Lentinus, Peniophora, Pycnoporus, Rigidoporus, Hygrocybe and, Psilocybe have an ability to decolorize CBB H-GR and Cibacron Red FN-2BL by more than 70%.
Their presence is widespread both in the vegetable kingdom (N,N-dimethyltryptamine or DMT found in Amazonian lianas), the fungi (psilocybine in fungi of the genus Psilocybe) and even the animal (bufotenine isolated from the skin of batrachians of the genus Bufus) (Dolengevich-Segal, Gomez-Arnau Ramirez et al, 2015).
Psilocybin, a psychoactive plant alkaloid found in Psilocybe mushrooms, is being investigated as a possible treatment for major depression.
