CSU PSY 252: EXAM 1 (DEANA DAVALOS)
ALL READING HIGHLIGHTS & CLASS
NOTES (ALREADY) PASSED!!
imaging techniques - ANSWERS-- Postion Emission, PET (Positron
Emission Tomography Scan, Radioactive glucose (sugar)
- MRI: Studies brain anatomy
-fMRI (functional MRI): Studies brain function
fMRI (functional magnetic resonance imaging) - ANSWERS-• Studies:
- Regional changes in blood flow
- O2 concentration
- Spatial resolution and temporal resolution
WATCH: https://youtu.be/8jc8URRxPIg (explain function)
Lesion Studies (old) - ANSWERS--deficits and damage
,-experimental vs. "experiments of nature"
TMS (Transcranial Magnetic Stimulation) (new lesion studies) -
ANSWERS-- Temp "lesion" (disruption)
- Vary Magnetic Field:
•electrical current w/ in any volume where it passes
• Hyper or Hypo
- "Virtual lesions" future of TMS
Wilhelm Wundt (1832-1920) - ANSWERS-set up the first psychological
laboratory in an apartment near the university at Leipzig, Germany;
trained subjects in introspection. Subjects were asked to accurately
record their cognitive reactions to simple stimuli
cognitive neuroscience - ANSWERS-- The study of neural mechanism
underlying the brain
- Methods based on premise that cognitive neuroscience or mental
state consists of a pattern of activity distributed over neurons
Tools used in cognitive neuroscience - ANSWERS-- EEG & MEG, Optical
dyes, TMS, fMRI, Single unit, Patch Clamp, Multi unit recording, light
Microscopy, PET, Micro lesions, 2-Deoxyglucose
, Neurophysiology - ANSWERS-- Explains the workings of the nervous
system
EEG (electroencephalogram) - ANSWERS-- Uses surface electrodes to
record the activity of underlying brain tissue
ERP (event-related potential) - ANSWERS-- Averaging across repeated
stimuli allows event-related activity to be identified
- New applications: BCI (Brain-computer interface)
- Usually labeled by polarity and latency, P300, P3 (???)
EEG vs ERP - ANSWERS-- Similar to EEG, but not related to an event (a
task)
eg. making a decision, reading a word
- In ERP uV is small in relation to the EEG in relation to the EEG (about
50 uv) (???)
- 1879 - 1st Successful formal psych lab
- 1881 - 1st journal devoted to psych labs
- 1883-1889 - 23 new psych labs
