Allows you to compare waveforms across conditons

This preview shows page 23 - 24 out of 24 pages.

Allows you to compare waveforms across conditons Inverse problem: projecting 2d information onto 3d brain Magneto-Encephalogram (MEG) Non-invaseively records neuromagnetic field to skull Super expensive IntraCranial EEG or ECog Electrodes are put in your skull Used mostly with epilepsy patients Can find generator site for epilepsy questions Invasive PET Measures metabolic brain activity via radioactive labels with short half-life. Scanner is passive array of gamma ray sensors. Record brian activity in 3d Sensitive -Metabolic measure, not direct brian activity. -Radioactive label. -Cannot repeat for 1 year. Modest spatial resolution (~1cm) -Poor temporal resolution Functional MRI Very rapid MRI movies Brain utilizes blood oxygen, which changes magnetic state of blood. Non-invasive Spatial resolution <1mm Temporal res. ~ Correlation vs. Causation Causation: Perturbation of the brain brain cognition measure task performance Correlation: Manipulate cognitive process cognition brain -> measure neural variable Most CogNeuro experiments are correlational so be careful in claiming causation Anatomy book: 12.1-12.5

Expect multiple questions on: Anatomy from 2 Quizzes (just the specific sections that the quizzes focused on) Strengths & Weaknesses of Cognitive Neuroscience Methods (e.g., EEG, fMRI, TMS, DTI/DWI, PET, MEG …) – Spatial resolution, timing resolution, invasiveness, sensitivity to neurotransmitters, etc. Cingulate cortex DACC coding cognitive factors with decision making Frontal pole Most complex part of the executive functioning Deals with abstraction and mentalization Really hard to image Dorsal medial PFC Pay attention, there is a big gap in reward prediction

    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.
