Question 5

Define and explain a CT scan

Answer 5

Computed Topography; X-rays stacked into a 3D model; Non-invasive, Spacial, Not-temporal, Structural

Question 6

Define and explain a PET scan

Answer 6

Positron Emission Topography; radioactive substances (tailored to specific brain function) are tracked using gamma cameras; Invasive, Spacial, Not-temporal, Functional

Question 7

Define and explain fMRI

Answer 7

Functional Magnetic Resonance Imaging; oscillating magnetic device directs the electromagnetic field of the water molecules found in the blood (BOLD signal); Non-invasive, Spacial, Not-temporal, Functional (and Structural)

Question 8

Define and explain TMS

Answer 8

Transcranial Magnetic Stimulation; oscilating magnetic field induces electrical current interfering with neuron fire; Non-invasive, not-spacial, Temporal, implies Causation

Midbrain

Answer 20

Superior and Inferior colliculi; visual and auditory movement and processing
Ventral tegmental area - reward
Substantianigra - movement
