Computerized Axial Tomography

• CAT

• PET

• MRI

• EEG

What technologies are used for CAT scan

• X-ray

• MRI machine

• Powerful magnets

• Electrodes

A scanner creates multiple cross-sectional images of the brain

• CAT

• PET

• EEG

• MRI

Positron Emission Tomography

• PET

• EEG

• CAT

• fMRI

A computer then creates 3-D images showing degrees of brain activity. Areas with the most activity appear in red.

Magnetic Resonance Imaging

• MRI

• PET

• CAT

• fMRI

What technologies are used in MRI

• MRI machine

• Computer creates 3-D images

• X-ray

• Electrodes

A computer analyzes the electromagnetic response, creating cross-sectional images similar to those produced by CAT, but with superior detail.

• MRI

• EEG

• CAT

• fMRI

Tiny, branchlike fibers extending from the cell body

• Dendrites

• Soma

• Axon

• Myelin Sheath
