Document Summary
Essay 1 has been posted - support from tas, library, mike, etc. Grammar: the difference between count nouns and mass nouns. Not necessary to study the entire brain; at what level of the nervous system we will study depends on area of interest. Individual neurons contribute to how we do the things we do. Instead of occipital cortex- allows us to see (brain scan) we can use metal electrode in occipital cortex, record impulses from individual neurons. Conclusion: populations of neurons that are specialized, prefer different orientations. The brain is organized like a building block (e. g. like lego, you can use them to build up a structure". Individual neurons are the building blocks to information processing. Ex individual neurons respond to different orientations, which come together to process shapes, orientation, etc. House: from far away, difficult to tell what the house is made out of. Closer: realize they are typically made of bricks.
