Human Research

Question 1

Electroencephalography (EEG)

Answer 1

Many millions of neurons are active at the same time.

Bad spatial resolution
Good time resolution

Question 2

Intracranial EEG (ECOG)

Answer 2

Electrodes are placed directly on exposed surface of the brain.

Good spatial resolution
Good time resolution

Question 3

Functional Magnetic Resonance Imaging (fMRI)

Answer 3

Neuroimaging to study brain function

Measures oxygen content in blood flow

Good spatial resolution
Bad temporal resolution

Question 4

Magnetic Resonance Imaging (MRI)

Answer 4

Brain anatomy

Question 5

Trans cranial Magnetic Stimulation (TMS)

Answer 5

Uses a magnet to activate or inactivate neurons.

Only for cortical areas

Bad spatial resolution

Question 6

Positron Emission Telegraphy (PET)

Answer 6

Function of the brain by measuring glucose levels.

High glucose = high activity

Question 7

Optogenetics

Answer 7

Use of light to control cells.

Used with mice. Biggest findings in last 20 years
