Brain analysis/scan techniques Flashcards
1
Q
MRI (Magnetic Resonance Imaging)
A
- Radio/magnetic waves
- DOES NOT show brain function
- Produces 2d and 3d images of brain structure
2
Q
fMRI (Function Magnetic Resonance Imaging)
A
- Functional
- Shows brain function
- Shows real time brain activity
- Shows brain structures activated
3
Q
PET (Positron Emission Topography)
A
- Radioactive tracer attached to sugar compounds in blood
- Track area of most blood flow
- Gamma rays are emitted
- Coloured images of brain
- Brain function
- Disease progression.
4
Q
ESB (Electrical Stimulation of the Brain)
A
- Probe
- Uses electrical impulses to activate different areas of the brain
5
Q
DBS (Deep Brain Stimulation)
A
- Surgery
- Implants device that activates brain areas responsible for body movement through electrical impulses
6
Q
CT (Computed Tomography)
A
- X-rays
- Cross-sectional images of the brain
- 3d images
- Identify disease affected areas
- Brain structure
- NOT brain function
7
Q
EGG (Electroencephalogram)
A
- Detects, amplifies, records electrical activity of the brain
- Measures brain waves in response to stimuli
- Cannot show specific location of activity
