Electroencephalography (EEG)
Study of electrical activity of the brain


Electromyogram ( EMG )
Record of muscle activity from electrical stimulation


Lumbar puncture ( LP )
Puncture of subarachnoid layer at 4th intervertebral
space to obtain CSF fluid for analysis


Magnetic resonance imaging ( MRI )
Uses an electromagnetic field and radio waves

to create visual images on a computer screen
