Document Summary
Network maps: gall, 1796, there are different parts of the brain that are responsible for different things. The anatomical wiring gives us a sense of this. If we can follow connections between parts of the brain, we can see how information gets from one place to another. But it doesn"t tell us what kind of information or the direction of flow of the information. Eeg: principle of integration, if we want to look at the functioning, we have to look at networks work together. You do the task hundreds of times so you have a critical mass of information. Once everything is averaged out, the dips and rises even out and you get to see the actual activity. Locus selection problem: early-selection model, remember the cocktail party example. Erp and locus of selection task: visuospatial attention, attend only to stimuli in box, respond with a clap (when you see smiley face in the box, ignore other stimuli.
