MAGNETOENCEPHALOGRAPHY
MEG, locates and measures magnetic field of brain.
S Q U I D
STRUCTURE OF MEG
The first measurement of the MEG by David Cohen at 1970’s.
CLINICAL APPLICATONS • Multiple Sclerosis • Alzheimer's Disease • Epilepsy • Schizophrenia • Sjögren's Syndrome • Chronic Alcoholism • Facial Pain • Thalamocortical Dysrhythmias
ADVANTAGES - DISADVANTAGES • Noninvasive • Easy to use • It is more expensive • High temporal resolution • Not as good as f. MRI at localising where precisely in the brain, activity is taking place. • High Precision • Measures brain function
