Periaqueductal Gray Matter (Wikipedia)

The periaqueductal gray (PAG), also known as the central gray, is a brain region that plays a critical role in autonomic function, motivated behavior and behavioural responses to threatening stimuli. PAG is also the primary control center for descending pain modulation. It has enkephalin-producing cells that suppress pain.

Anatomical terms of neuroanatomy

The periaqueductal gray is the gray matter located around the cerebral aqueduct within the tegmentum of the midbrain. It projects to the nucleus raphe magnus, and also contains descending autonomic tracts. The ascending pain and temperature fibers of the spinothalamic tract send information to the PAG via the spinomesencephalic pathway (so-named because the fibers originate in the spine and terminate in the PAG, in the mesencephalon or midbrain).

This region has been used as the target for brain-stimulating implants in patients with chronic pain.

What is this "Wiki" & how does the cannabis community benefit?

The Green CulturED Wiki enables you to explore, learn, and share through a knowledge base tailored to the cannabis industry. It functions like an encyclopedia, lexicon, glossary, wiki, or dictionary. This tool is useful for industry learners and professionals to learn more about resources, programs, and terms specifically in the cannabis sector.

Yes, new terms can be added by crafting individual entries, each with its own dedicated page and unique URL. By sharing resources, information, and industry information, users are able to foster community, growth, and learning. Once submitted, a glossary term is reviewed by the Green CulturED team, which will then approve or deny the submission. 

While the Green CulturED Community Wiki does not impose specific content restrictions, it is essential to adhere to general web content guidelines, which include avoiding misinformation and respecting copyright laws. For cannabis-related glossaries, it’s critical to ensure the accuracy and legality of the information presented. In addition, common courtesy and “netiquette” are part of our community user agreement, and it is crucial to maintain those levels of respect when adding new terms, comments, etc.

Glossary term categories serve as a reference tool that enhances usability, navigability, and educational value by organizing terms into groups such as industry brands, consulting firms, and seed banks.

The Green CulturED Wiki supports comments on individual glossary terms, enabling users to engage in discussions or leave feedback. This feature fosters collaborative learning and knowledge sharing within the cannabis community.
If you encounter incorrect or outdated information, please contact the site administrators directly or use the commenting feature to report inaccuracies for review and correction. Green CulturED Wiki allows for revisions, enabling updates and corrections.
Green CulturED Wiki utilizes user rights and capabilities for managing and reviewing user-contributed terms. Administrators can set specific permissions and establish review processes according to their policies.
