Evoked Field

Evoked field (pronunciation: /ɪˈvoʊkt fiːld/) is a term used in neuroscience to describe the electrical or magnetic field generated by the nervous system in response to sensory stimulation.

Etymology

The term "evoked field" is derived from the word "evoke", which means to bring or recall to the conscious mind, and "field", referring to an area or space where a given effect (such as an electrical or magnetic effect) exists.

Definition

An evoked field is the change in the electrical or magnetic field of the brain that occurs in response to a sensory stimulus. This change can be measured using techniques such as electroencephalography (EEG) or magnetoencephalography (MEG), and is used to study the functioning of the brain and the nervous system.

Related Terms

  • Evoked potential: This is a measure of the electrical activity of the brain in response to a specific sensory stimulus. It is a subset of the evoked field.
  • Event-related potential (ERP): This is a type of evoked potential that is time-locked to a specific sensory event.
  • Sensory evoked potential (SEP): This is a type of evoked potential that is elicited by a sensory stimulus.
  • Visual evoked potential (VEP): This is a type of evoked potential that is elicited by a visual stimulus.
  • Auditory evoked potential (AEP): This is a type of evoked potential that is elicited by an auditory stimulus.
