On
January 25, 2011, Dr. Raymond Swanson explained to the youth and community of
Marin the modern devices and techniques used in neuroscience.
About
the Seminar:
Dr. Swanson is the professor and
Vice-Chair in the Department of Neurology at UCSF. He first became interested in neuroscience
when he took at class in Physiological Psychology as an undergraduate. His lab (Swanson Lab) does medical research to understand
what will keep neurons alive, in hopes of improving the lives of patients
suffering from strokes.
He discussed the past and current
methods of neurological research.
Comparing normal brains and brains with differences is how we determine what certain parts of the brain do. He gave the famous
example of Phineas Gage who had his frontal lobe destroyed through an accident
when building a railroad. We saw major
differences in Gage’s abitlity to have normal human controls (eg: sit still)
and plan ahead, indicating that the frontal lobe had to do those human traits (http://www.youtube.com/watch?v=FrULrWRlGBA the
story of Gage in song form). Dr. Swanson
referred to this method of brain research as “breaking the brain”.
The current method of brain research
that is superior to breaking the brain is using a fMRI (functional magnetic resonance imaging). The fMRI began dominating neuroscience research in the early 1990's. This machine gives us non-invasive magnetic resonance
imagery into the inner workings of the brain.
While this has progressed neuroscience research greatly, it can only
show major energy shifts in the brain, so we cannot yet understand all the neurons
involved in every process.
