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.
