Can a frightening experience during pregnancy affect the development of an unborn child’s brain? Yes.
Hillary Clinton fainting at the 9/11 memorial this weekend has raised concern and speculation over possible causes. There are three causes of fainting.
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.
As we turn the page on 2014, here’s a list of some of the year’s highlights in neuroscience – along with a heavy dose of speculation about what they might mean for the future of the brain.
Marijuana use is legal in many states for medical purposes, most of them dealing with neurological conditions (pain, epilepsy, tremor, multiple sclerosis, and many others). From the perspective of a neuroscientist researcher, the situation with respect to “medical marijuana” is absurd. Continue reading
Typically we are introduced to the nervous system by analogy to an electrical circuit, like a door bell or a telephone line carrying a signal rapidly over long distances to activate a specific process. Never mind that electrical impulses are not transmitted through nerve axons anything like electrons flowing through a copper wire, this electronic circuit analogy is useful up to a point. If you want to understand how the brain works at a more complex level, you are going to need a new analogy, and if you play an acoustic guitar you’ll find it under your fingertips.
We are constantly hearing about 3D printing in the media. Whether people are making 3D-printed cars, guns, or even organs, this technology is becoming wild with the thousands of different applications. My new favorite: a 3D printed brain. Continue reading
