Insights into the Hippocampus
|
view preview
When Henry Molaison (now widely known as H.M.) cracked his skull in an accident, he began blacking out and having seizures. In an attempt to cure him, daredevil surgeon, Dr. William Skoville, removed H.M.'s hippocampus. Luckily, the seizures did go away — but so did his long-term memory! Sam Kean walks us through this astonishing medical case, detailing everything H.M. taught us about the brain and memory.

Where else are taste buds found in the body?
|
view preview
Lungs have 'taste buds' which can detect bitter-tasting compounds, although aren't connected to the brain! The taste receptors in the lungs are the same as those in the mouth except they are not found in clusters and do not send any signals to the brain.

Miraculous headless chicken
|
view preview
This is Miracle Mike, the Headless Chicken. Beheaded by a farmer for dinner in 1945, part of Mike's brain was accidentally spared, which allowed him to live for another 18 months. In fact, Mike thrived without his head, gaining more than 2 kg as the farmer fed him food and water by depositing it into his exposed oesophagus.

Drinking seawater to survive
|
view preview
A seagull on a glass roof looking really cute. Seagulls are able to drink seawater to survive thanks to salt glands just above their eyes. These glands eliminate excess salt from the seawater and flush it out of the birds' nostrils in liquid form, an action that's often mistaken for a sneeze.
