Pre-thinking:

Lozano and fellow neuroscientists have been working directly with the brains of patients implanting electrodes that will vary the amount of current introduced to the brain. They have found that various brain dysfunctions can be significantly altered through these procedures. Listen for the new science and how its potential will affect us.

Why you should listen:

Andres Lozano remembers the most satisfying case of his career – helping a boy with a genetic form of dystonia which had twisted his body to the point where he was only able to crawl on his stomach. While he didn’t respond to drugs, he responded wonderfully to deep brain stimulation. Three months after surgery, he was walking like a normal child. He’s now a college student leading a normal life.
Lozano is a pioneer in deep brain stimulation. His team has mapped out areas of the human brain and pioneered novel surgical approaches to treat disorders like Parkinson’s disease, depression, dystonia, anorexia, Huntington’s and Alzheimer’s disease. The chairman of neurosurgery at the University of Toronto, he holds both the R.R. Tasker Chair in Functional Neurosurgery at the Krembil Neuroscience Centre and a Tier 1 Canada Research Chair in Neuroscience.

Who is he:

Lozano has over 400 publications, serves on the board of several international organizations and is a founding member of the scientific advisory board of the Michael J. Fox Foundation. He has received a number of awards including the Olivecrona Medal and the Pioneer in Medicine award, has been elected a Fellow of the Royal Society of Canada and the Canadian Academy of Health Sciences and has received the Order of Spain.

Questions:

  1. When did Meso Americans begin opining the cranial cavity?
  1. What is similar in Electroconvulsive Therapy and the kind of procedure of which Lozano speaks?
  1. The first example he give is of a woman with ________ disease?
  1. As a future Psychologist you might be most interested in what kinds of illnesses Lozano has worked with?
  1. Neurosurgery is expensive. Discuss with someone your take on this “quality of life” type operation.
  1. What areas of the brain seemed most effected by depression? If you were looking for behavioral clues, to possible brain problems, what would you look for?

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