Friday Facts: Week #13

Greeting everybody, HAPPY FRIDAY!
The use of Cannabis for medicinal purposes dates back to around 4000 years ago and all over the world including China, India and Middle East. In the 19th century (before it was made illegal in the UK) J.R.Reynolds (a physician) prescribed cannabis for Queen Victoria in order to relieve menstrual cramps, morning sickness and labor pains.

Dogs obtain an alar fold - a bulbous obstruction inside their nostrils which heightens their sense of smell. In a typical dogs nose there are roughly 220 million olfactory cells, whereas humans only have a mere five million. Dogs’ sense of smell is largely 10,000-100,000 times superior to that of humans. It is no secret dogs can detect diseases such as cancers. A study in 2006 confirmed this theory when three Labrador Retrievers and two Portuguese Water Dogs went through several weeks of training with breath samples that contained volatile organic compounds (VOCs) which are associated to the presence of cancer. The dogs positively identified 99% of the lung cancer samples.

The sound of babies crying makes us more vigilant, even if we’re not the baby’s parents. In a study conducted at the University of Oxford, brains were scanned of 28 people while they listened to the sound of babies crying; adults crying; cats meowing; and dogs whining. The scans showed an outbreak  of activity in the Middle Temporal Gyrus (an area implicated in emotional processing and speech) and the Orbitofrontal Cortex (area known for its role in reward and emotion processing) in response to the sound of a baby cry. Therefore a baby's cry is identified as important even before our brains have had a chance to fully process the information.
