A cold-stimulus headache, colloquially known as an ice-cream headache or brain freeze, is a form of brief pain or headache commonly associated with consumption (particularly quick consumption) of cold beverages or foods such as ice cream, popsicles, and snow cones.
So, why the heck do we. Brain freeze is so serious it has a scientific name: sphenopalatine ganglioneuralgia. You drink or eat something cold very fast and BOOM, your head feels like someone's ...

Now, after the lab team’s decade of close collaboration with scientists at Google, that data has turned into the most detailed map of a human brain sample ever created. 300 million images
It shows neurons and their connections along with blood vessels and other components of a millionth of a brain. For the map, the 1 mm³ sized fragment was sliced into about 5,300 pieces of about 30 nanometer thickness which were then each scanned with an electron microscope. The interactive map required 1.4 petabytes of storage-space.
Most Alcor members fund cryonic preservation through life insurance policies which name Alcor as the beneficiary. [7] Members who have signed up wear medical alert bracelets informing hospitals and doctors to notify Alcor in case of any emergency; in the case of a person who is known to be near death, Alcor can send a team for remote standby.
Multiple topographic maps is a feature that is advantageous because it allows maps of different sizes that would accommodate varying levels of acuity and details in signals. A more detailed map has more neurons that would take up more area than a more global map, which would require fewer connections. [13]
Cryonics proponents go further than the mainstream consensus in saying that the brain does not have to be continuously active to survive or retain memory. Cryonicists controversially say that a human can survive even within an inactive, badly damaged brain, as long as the original encoding of memory and personality can be adequately inferred ...
