Evoked field
From Infogalactic: the planetary knowledge core
Lua error in package.lua at line 80: module 'strict' not found. Evoked fields are part of the magnetoencephalogram. They are brain signals evoked by sensory stimulation, but usually buried by the ongoing brain activity. Repeating the stimulus multiple times and averaging the signals reduces the uncorrelated ongoing activity and reveals the evoked field.
Evoked fields are the magnetoencephalographic equivalent to evoked potentials, which are part of the electroencephalogram.
