Question 1

Electro physiology

Answer 1

Record currents from individuals or groups of neurons

Question 2

Microdialysis

Answer 2

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

Question 3

Dopamine microdialysis

Answer 3

Dopamine flow back after normal fluid is put into tube and then measure concentration

Question 4

Optogenetics

Answer 4

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
