SciShow debunks the myth that you only use 10 percent of your brain. So, how much do you really use? And how do we know?
For hundreds of years, psychiatry has treated voices and hallucinations as an enemy - regarding them as 'insanity' or 'madness' and seeing them as something to be quashed and even frightened of. But today, new scientific and psychological insights into how the brain works are leading to a radical rethink on what such experiences are - and how they should be treated. Horizon follows three people living with voices, hallucinations and paranoia, to explore what causes this kind of phenomena. Providing a rare first-hand insight into these experiences, they reveal just what it is like to live with them day to day. They examine the impact of social, biological and environmental influences on conditions traditionally associated with insanity, such as schizophrenia and psychosis, and within the film they look at how new ways of understanding the brain are leading to a dramatic change in treatments and approaches, and examine whether targeting the root causes of psychosis can lead to recovery. Above all, they try to uncover why it happened to them - and whether it could happen to you.

Lyme disease, a mysterious tick-borne illness, is the fastest spreading vector-borne disease in the United States, and over the past decade, the tick that carries Lyme has been spreading across Canada with alarming speed. Ticked Off: The Mystery of Lyme Disease, is a fascinating and eye-opening documentary that explores a disease that has devastating effects, is often misdiagnosed and mistreated, and continues to be mired in a medical controversy. More than 30,000 cases are reported in the USA every year, but the real number could be as high as 300,000. And despite hard evidence that the Lyme-carrying, deer tick has already established populations across Canada, some people claim that patients here are still being told that they cannot contract Lyme in this country. Doctors agree that if it’s caught early Lyme disease can usually be cured with two to four weeks of antibiotics. There are others who believe that if it’s not caught early, the infection can develop into a debilitating condition they call Chronic Lyme. Yet unlike West Nile, Encephalitis or SARS, where the medical profession and scientists joined forces to find better treatments or a cure, many patients, who claim to have chronic Lyme, say that they are being denied treatment and left to suffer. So why is this happening?
