Seeing the Big Picture: How the Brain Manipulates our Visual World

When we open our eyes, are we perceiving reality? Why do we fail to agree on the color of “The Dress” (that went viral in 2015)? Have you ever glanced at ticking clock and noticed the second-hand suddenly freeze for a split second?

Neuroscience research suggests that the brain evolved to make rapid, best-guesses about the objects in our environment, rather than create a one-to-one representation of the world. Through stories and demonstrations, Dr. Mark Pitzer will discuss some of the effects of this strategy and how our visual system can highlight some objects, delete others, and alter our conscious awareness in an attempt to help us navigate our visual world.

We’re excited to welcome Mark Pitzer back to Science on Tap! (Remember that great Making Memories show??)

Mark Pitzer, Ph.D. is a neuroscientist at the University of Portland. For the last 25 years he has worked to better understand and treat diseases of the brain, including Parkinson’s and Huntington’s diseases. Currently, his lab studies how developmental influences in the womb can alter the number of dopaminergic neurons involved in movement and reward. Mark is also an award-winning teacher that uses the findings from the fields of learning and neuroscience to invoke enduring enthusiasm, curiosity and deep learning in his college students.
