Impact of the 'brain school' training on participants' mental health

In 2014, a U.S. brainwave scientist claimed he could increase people’s creativity and cure their traumas. And he got permission to experiment on Indigenous children in Canada, offering an all-expenses-paid trip to Victoria, B.C.

But a decade later, some study participants say the testing they went through — which included staff attaching electrodes to their heads and being asked to talk about the most traumatic moments of their lives — wasn’t what they signed up for and may have left side-effects.

We hear from CBC’s Geoff Leo about what his investigation turned up and why critics are demanding more accountability and transparency over how the study was approved in the first place.
