Class Notes 9-8-16 A Clock Work Orange clip was shown and it was suggested that we watch it fMRI While Viewing a Film - Researchers had people watch films while they had an fMRI - They would look for what areas of the brain activated in all the participants at certain points in the movie - Results: Parahippocampal area (PPA): activated for locations or places (house, bedroom, etc.) Extrastriatal body area (EBA): sensitive to body analysis. Activated parts of bodies or whole bodies but NOT faces (arms, whole person, leg, etc.) Localization of Function: Perception Fusiform Face Area (FFA) responds specifically to faces - Temporal lobe - Damage to this area causes prosopagnosia – the inability to recognize faces Huth et al. (2012) - Used fMRI and video to localize function - Found that we have areas in the brain dedicated to complex stimuli Distributed Processing in the Brain - In addition to localization of function, specific functions are processed by many different areas of the brain - Many different areas may contribute to a function Neural Networks - Groups of neurons or structures that are connected together Diffusion Tensor Imaging - Uses MRI Measures water density of axon fibers for integrity and strength rather than measuring iron like a typical MRI End of Chapter Notes from Video: Brain Games Focus on illusions and games Some of the names may be misspelled, sorry! Beau Lotto: experimental neuroscientist - Your brain uses shadows to see things in general and where they are in space - Our brain uses shadows to know the behavior of objects in space - Shadows change our perception of where things are Ex: If a shadow is directly under an object it looks like it’s on the ground, if a shadow is in front of or behind and object it looks like the object is in the air (think of a basketball) - Context changes things – the color AROUND things changes how we see them Ex: a light yellow sheet looks more yellow when you put it next to a white sheet - Color is all in our heads, it’s a construct Ex: In the video we were shown a giant cube with many colored squares. The brown tile looked brown when it had a white outline and it looked orange when it had a black outline - Shadow and color are imperfect indicators Bas Rockers: studies depth and perception cues - Our brain uses 2D cues to create a 3D scene in our mind - Brain uses familiar patterns and lines to created images Because the lines and patterns are familiar, the brain is trying to create an image of something familiar that we’ve seen before John Crawford - The brain is hardwired to recognize human movement (or human- like) - It is easy for the brain to decide what movement is happening just by viewing joints - The brain is best at identifying activities you’re most familiar with Jonah Lehrer: studies mirror neurons - We enjoy being spectators because our brain acts as if we’re participating in the activity Ex: When you watch a person get hurt in a movie and you feel a little pain and adrenaline - Rubber Hand Experiment: This experiment links the participants brain to the fake hand and that’s why it responds as if the hand is real and connected to the body Ex: The rubber hand is hid with a heavy object and the participant jumps/squeals as is if happened to their real hand - About 30% of the brain is devoted to sight Your brain can change what your other senses experience to match what you see Josh McDermet - When your brain hears things it tries to turn the sound into words, even if words aren’t being spoken Lera Boraditzky - Your brain has evolved to quickly decipher words and letters - When your brain sees something ambiguous it tries to use other clues to solve the ambiguity Daniel Kish - He has been blind since he was 13 months old - He is able to walk all around town without being hurt as well as ride a bike because he uses auditory cues to decipher what is going on around him
