Concussion Movie Reignites Important Issue

It is fairly remarkable that Concussion, the movie, exists. Ten years ago, the public did not know much about concussions and other forms of brain trauma. People weren’t watching football games and thinking about the long-term neurological effects of the brutal hits. Around 2009, the National Football League (NFL) started catching heat for its outdated concussion policies. In 2013, a book and corresponding documentary that tackled the issue, League of Denial, were released. And now, at the end of 2015, Hollywood has brought us a major motion picture that stars Will Smith as a neuropathologist fighting to reveal the truth about head trauma in football players.

How the Neurotoxin in Dungeness Crab Causes Brain Damage

The California Fish and Game Commission has banned crab fishing until further notice after detecting high levels of a neurotoxin in Dungeness and rock crabs. The toxin, domoic acid, is produced by certain types of planktonic algae, and it becomes concentrated in tissue of crabs and other marine organisms during plankton blooms. People who consume sufficient quantities of the toxin develop amnesic shellfish poisoning, so named because it kills neurons in a part of the brain that is critical for memory. Here’s how it works.
