The Instituto do Cérebro (Brain Institute, ICe) is an academic research institute of the Federal University of Rio Grande do Norte (UFRN) in Natal, Brazil, focused on neuroscience research, education and public outreach.

Chacruna is a nonprofit psychedelic education and advocacy platform based in the United States with global reach through online publishing, courses, conferences, and multilingual programming. Its work centers on psychedelic plant medicines, ethics, cultural justice, reciprocity, and Indigenous knowledge, with content and activities aimed at researchers, clinicians, educators, policy audiences, and the broader public. The organization says it bridges ceremony and science and makes academic knowledge more accessible through public-facing education. Chacruna plays an explicit role in psychedelic justice and policy-adjacent advocacy by foregrounding cultural context, equity, and protection of sacred plants and traditions. Current documented initiatives include the Indigenous Reciprocity Initiative of the Americas, which supports community-led Indigenous projects, the Psychedelic Culture conference, the bilingual Chacruna Latinoamérica platform, and courses on diversity, culture, social justice, ceremony, ethics, and reciprocity. These activities make it a potential partner for researchers, clinicians, funders, and policy groups seeking cultural consultation, educational programming, and community-centered collaboration.
