Knowledge of Brain Structure/Function

Question 1

What is spatial resolution?

Answer 1

Ability to distinguish small, detailed areas and have clear representation in brain regions

Question 2

What is temporal resolution?

Answer 2

Ability to detect rapid changes over time in the brain with high precision

Question 3

EGG: Measures Brain Activity

Answer 3

Non-invasive, good temporal resolution
Poor spatial resolution
Detect epilepsy and sleep disorders

Question 4

CT Scan: X-ray imagining

Answer 4

Detect brain injuries quickly
Low detail compared to MRI
Identifies brain bleeds/ fractures

Question 5

MRI: Brain Imagining

Answer 5

High resolution
Expensive and subject must stay still
Diagnosing tumors and structural abnormalities

Question 6

fMRI: Measures brain activity

Answer 6

High spatial resolution
Expensive and subject must stay still
Research functions and maps cognitive processes
