Phosphene. Not to be confused with phosphine (PH3) or phosgene (COCl2). Artist's depiction of mechanical phosphene A phosphene is a phenomenon characterized by the experience of seeing light without light actually entering the eye. The word phosphene comes from the Greek words phos (light) and phainein (to show).[1] Phosphenes are flashes of light, often associated with optic neuritis, induced by movement or sound.[2][3] Phosphenes can be directly induced by mechanical, electrical, or magnetic stimulation of the retina or visual cortex as well as by random firing of cells in the visual system. Causes[edit] Mechanical stimulation[edit] The most common phosphenes are pressure phosphenes, caused by rubbing the closed eyes.
Another common phosphene is "seeing stars", from a sneeze, laughter, a heavy and deep cough, blowing of the nose, a blow on the head or low blood pressure (such as on standing up too quickly or prior to fainting). Electrical stimulation[edit] Other causes[edit] Explanation[edit] Notes. Mind Mapping.
Discover the world's most endangered species. Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species. Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world.
Since 2013 Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. Therefore, the charity had been using its reserves to keep the project online and was unable to fund any dedicated staff to maintain Arkive, let alone future-proof it, for over half a decade. Despite appeals for support, just 85 of our 5.6 million users in 2018 made a donation.

Chances are they would've ended up brainless morons with or without the pot. It's quite frankly not strong enough of a narcotic to destroy one's life such as you describe. It's very dependent on the user's persona. @Tadashii: Are you also for alcohol and tobacco prohibition? Those ruin more lives every year then marijuana has ever. Wow- Tadashii, pot is not meth or cocaine. Marijuana is not a drug that people become addicted to and end up in the gutter from. Yes, its a chemical that can intoxicate and has been embraced by, and been the cause of some lazy folks, underachievers, and Grateful Dead fans not amounting to much.
Pot is like anything else- tobacco, alcohol, vicodin, valium, caffeine, etc. Cannabis has great promise for any treatment that requires appetite stimulant (such as cancer, HIV, etc), and has also been found to act as an anti-inflammatory or nausea reliever, Don't just stamp marijuana "evil". Yes I am against alcohol too and I agree that it's worse than pot. 125 Great Science Videos: From Astronomy to Physics & Psychology.
