a. As tasks get harder, more and more anterior portions are used b. High and low filtering task – words have either high filtering stimulus (you can think of many things to do with it) or low filtering, and people with dlPFC – dorsal lateral prefrontal cortex - damage can’t come up with many c. Rule following, capture, and perseveration - Wisconsin Card Sorting Test - Card matching game with many attributes, tester just tells the patient if they are correct or incorrect - Rules change and patients aren’t told - Patients with dlPFC damage can’t change and adapt to the new rules d. Inhibition - Small beep (auditory) - Parietal damage, no difference - Temporoparietal damage, less response for people with lesion (this part is the auditory part) - Frontal damage, more response for people with lesion, loss of inhibition when frontal lobe is injured e. Are prefrontal patients better at some tasks? - Move one matchstick to solve the problem

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
