Rely on many other cells of the visual pathway to feed them detailed information fMRI can look directly at brain activity Areas of the cortex activate when are showed a face Areas of the frontal lobe are involved in short term memory for faces Function in long term storage of facial recognition Seeing is perception Takes about 3/10 of a second Inverted Vision Image is inverted in the retina Visual cortex perceives things as right side up London student experimented by wearing glasses that made everything upside down Reflection on water shows images upside down Sensory Motor Integration Action/reaction Input/output Greg Louganis
Famous diver who demonstrates how the his brain works together to get a 10 Huntington’s Disease Dr. Nancy Wexler Research in Venezuela o Can affect movement, cognition, and judgment o Affects 1/10,000 people o Affects ¼ people in a family in Venezuela o Don’t know when it starts o Cells in the middle of the brain die o Spinal fluid is enlarged to the size of a walnut o Affects the brain o 50/50 chance of inheriting it if parents have it o Symptoms are apparent around the 30’s or 40’s o No cure for disease o Gene has been identified o Possible to determine if they can get the disease o Information is just as “toxic” as chemotherapy Perception involves multiple levels of processing Shows how fluid the brain is at processing information Brain is able to learn and grow rapidly to change it adapt to is environment Highest level in coordination Greg Louganis Most visual research is done on cats Have complex visual processing Similar to humans Cells fire when something looks like a face and doesn’t fire when the face is distorted Famous person who died of Huntington’s disease Woody Guthrie Medical, ethical, and moral reasons that this disease is an issue Only genetically!!! Only way to stop disease is by stop having children Genocide The Secret Life of the Brain (Video 10/2) A baby’s brain is less than 1 pound A piece of the brain about the size of a grain of rice contains about 10,000 nerve cells The brain reacts to light and sound The brain of a pre-mature baby is not fully developed Development can be compared to a play but there is no director, actors…etc By 4 weeks, the neurons are forming at a rate of 5000/minute Are never replaced…function into old age Neurons travel in waves Migration Evidence shows that young neurons know where they are migrating to and recognize their position in the brain Neurons are born from stem cells
Took a decendant of a brain cell, implanted it in a brain, and then watched it migrate Followed orders from the cells surrounding it Watched a neuron in the brain migrate and saw that its true to its genetic diversity By the time a young neuron starts migration, it knows where its supposed to go and what to do
