## Brain imaging techniques
* Computerized tomography (CT) scan uses X-rays in 3-dimensions to generate a brain image
* Can be digitally sectioned to show internal areas of the brain
* Can distinguish between grey matter and white matter, see the ventricles, has resolution of several millimeters

## Magnetic resonance imaging (MRI)
* Uses rotating magnets to generate image
* Non-invasive
* Can view images from any angle
* Resolution under 1 mm
* Can be adapted to do functional MRI imaging

## functional magnetic resonance imaging (fMRI)
* Oxy-hemoglobin and deoxy-hemoglobin have different magnetic resonance signals
* Brain areas activated by a specific task utilize O2, then a pulse of O2 comes back and creates an influx of oxy-hemoglobin
* Can repeat task many times over
* Spatial resolution millimeters
* Temporal resolution seconds
