EEG and ERP

• Scalp surface electrodes
• since 1924, modern more precise
• Cheap and powerful
• tell difference between victims of intentional vs accidental harm
• Event Related Potential.
• Can tell for hearing problems versus autism
• Hyperscanning is a technique that allows the simultaneous recording of brain activity of different subjects.
  • Can be done by both EEG and FNIRS
• Electroencephalogram (EEG) is a medical test that records the electrical activity of the brain by placing small electrodes on the scalp
• Functional near-infrared spectroscopy (fNIRS) is a non-invasive brain imaging technique that measures brain activity by using infrared light to record blood flow changes in the brain:

Magnetoencephalography (MEG)

• With electricity comes magnetism
• Records tiny magnetic things in the brain
• Measures brain activity localized and accurately
• It is mobile.
• Need to be in a shielded room

Single Cells

• Surgically implanted electrode

Stimulation

Electrodes implanted in brain (to stimulate)

• Can stimulate with magnets, electricity, or light

Lesion

Compare behavior before and after damage

• Phineas Gauge in 1850s with metal road through head, he survived, they could monitor differences in personality

Biochemical Methods I

• Methods to get drugs into brain
• Microdialysis (see chemicals in part of brain)

Biochem Math II

• fMRS - Check chemical change in awake behaving person, not intrusive

Molecular Genetics (ch 5)

• Families used, especially twins
• Adopted children
• Compare genes of Scizophrenic person versus not
  Reverse Genetic Screen-
• Dr. Yoda wants to know what genes are different in Mandalorians and Ugnaughts. You are most likely to recommend a reverse genetic screen.
• This is False
• an experimental molecular genetics technique that enables researchers to make clear gene function by examining changes to phenotypes (of cells or organisms) caused by genetically engineering specific nucleic acid sequences (within DNA or RNA).
