Mapping Psilocybin’s Brain Effects to Explore Potential for Treating Mental Health Disorders
Psilocybin is a natural ingredient found in “magic mushrooms.” A single dose of this psychedelic can distort a person’s perception of time and space, as well as their sense of self, for hours. It can also trigger strong emotions, ranging from euphoria to fear. While psilocybin comes with health risks and isn’t recommended for recreational use, there’s growing evidence that—under the right conditions—its effects on the brain might be harnessed in the future to help treat substance use disorders or mental illnesses. To explore this potential, it will be important to understand how psilocybin exerts its effects on the human brain. Now, a study in Nature supported in part by NIH has taken a step in this direction, using functional brain mapping in healthy adults before, during, and after taking psilocybin to visualize its impact. While earlier studies in animals suggested that psilocybin makes key brain areas more adaptable or “plastic,” this new research aims to clarify changes in the function of larger brain networks and their connection to the experiences people have with this psychedelic drug.
Not A Blank Space: Policy Considerations for AI in Research
Forecasting policy needs is challenging due to rapid technological advances. NIH’s Data Management and Sharing Policy includes flexibility for evolving tools like artificial intelligence (AI), which enhances research but requires responsible use. Learn more about how NIH provides resources to ensure AI research adheres to existing policies and plans to update guidelines as technology progresses.
NCBI’s PopSet Database to Retire Effective January 2025
Beginning in January 2025, NCBI’s PopSet database will no longer be available. While PopSet web pages (example) will no longer be accessible, individual sequences of PopSet will still be searchable and accessible in Nucleotide as independent records (example). A link under ‘Related information’ on a GenBank record page will also let users access other sequences … Continue reading NCBI’s PopSet Database to Retire Effective January 2025
