Electroencephalogram

• EEG measures electrical activity in the brain using electrodes which are attached to the scalp.
• • Provides an overall account of brain activity.
  • scan recording represents the brainwave patterns that are generated from the actions of thousands of neurons.
• Often used by clincians as a diagnostic tool as unusual arythmic patterns of activity may indicate neurological abnormalities such as epilepsy, tumours of some sleep disorders.
• A record of the tiny electrical impulses produced by the brains activity. By measuring characteristic wave patterns, the EEG can help diagnose certain conditions of the brain.


  Electroencephalogram
• When neurons start to generate the same patterns of neural activity at the same time it is synchronized.
