The dark web hosts a specialized wildlife trade market where roughly 90% of advertisements involve recreational drugs. Over five years, 153 species appeared in about 600 advertisements per year. Most traded species are plants, but fungi and animals also appear. Psychedelic species dominate, with 45 species identified, including 19 species of Psilocybe fungi. The native ranges of drug plants cluster in Central and South America. A smaller portion of trade involves medicinal products, clothing, decoration, and pets. Current conservation and biosecurity risks from dark web wildlife trade appear low, but trade could increase if enforcement on e-commerce and social media reduces access for traders.
A spectrum of consciousness and awareness, including signs of implicit learning and electrocortical biomarkers, may be present during deep hypothermic circulatory arrest (DHCA), despite the absence of visible signs of consciousness. In a prospective study across 10 hospitals with 36 DHCA patients, 29 had a tablet set up to deliver audiovisual stimuli. All had EEG and NIRS monitoring, but only 9 had usable EEG data. Delta EEG waves were observed during circulatory arrest in 3 of those 9 patients. None had explicit recall of the three fruit names, but 3 of 36 correctly guessed them, suggesting implicit learning, and 3 recalled other memories, including themes of a death experience. This may help explain negative psychological outcomes in cardiac arrest survivors.
