EEGs

Cards (3)

  • EEGs
    22-34 Electrodes on a cap, the sum of activation in each cortex under the electrode measures activity, shown as brain waves, high amplitude = high intensity
  • (+) A03: Historical Importance

    Important in sleep research and diagnosis, high temporal resolution due to recording in milliseconds
  • (-) A03: Spatial Resolution
    Poor spatial resolution due to relying on summation of neurons, cannot detect deep into the brain
