Parkinson’s, depression and the switch that might turn them off by Andres Lozano


The brain, also called the “masterpiece of creation“, is still the most mystic organ of the human body. Endeavors of understanding how the brain functions are as old as human history itself and although tremendous progress has been made in neuroscience, there are still some secrets that no brain scanning machine can map… yet. Click here for a great visual history of the brain that will give you a clue on how old research on the brain is.

Diseases like Parkinson’s, Amzheimer’s, dystonia, depression, etc., still have no cure and seem to remain a myth for even the brightest minds in neurology. But what if finding a cure is not the right approach in this case? The chair of neurosurgery at the University of Toronto, Andres Lozano, has asked himself this question and realized that a treatment for these diseases doesn’t necessarily imply their complete removal from the brain. What if we can play with those parts of the brain that are affected by the disease by pushing bits of electricity? The talk he gave at the TEDxCaltech provides the answer to this question.

Brain stimulation allows surgeons to send out low or high electric impulses to almost any area of the brain and thus correct dysfunctions of the brain. We invite you to see for yourself the dramatic impact that this technique has on a woman whose motion system is severely affected by Parkinson’s and a young oy whose life gets a “positive twist”. And that’s not all: now mood and cognition disorders can also be corrected.
