Psycho physiological methods in neuroscience Flashcards
Electro physiology
Record currents from individuals or groups of neurons
Microdialysis
Sampling neurotransmitter levels from discreet brain regions in a living organism, usually not human, can accurately quantify neurotransmitter contractions at 10 minutes and higher intervals
Dopamine microdialysis
Dopamine flow back after normal fluid is put into tube and then measure concentration
Optogenetics
Manipulating what’s going on in the brain, generating action potentials.
Take the gene from algae to make neurons that express ion channels, light determines if it’s on or off
In optogenetic‘s yellow light ________ the brain _______and blue light turns the brain ______
Turns, off, on
Electroencephalography
Records electrical activity, shows when brain activity occurs but not where
Event related potential
Computer software, relate brain waves back to particular event
MRI (magnetic resonance imaging)
Uses magnetic fields to produce finally detail images of the structure of the human brain another soft tissue
Shows where not when
Detailed and grey
FMRI
Variation of MRI tells about brain activity during
Blue, somewhat detailed
Pet scan
Measures blood flow to brain areas in active brain
Radio active form of oxygen is injected into participant
Colourful and blocky
What do mri, fmri, pet scan have in common
Looking at scans of the brain

Uses inferered light
