Definition

1. Noun:
   • A medical instrument for recording brain activity: An electroencephalograph is a device used in medicine and neuroscience to detect and record the electrical activity produced by the brain. The recordings it produces are called electroencephalograms (EEGs).

Usage Examples

• Noun:
  • The neurologist used an electroencephalograph to monitor the patient's brain waves during sleep.
  • Modern electroencephalographs are much more portable than the early models.

Advanced Usage

• In a clinical context: The term is often used when discussing the diagnosis of neurological conditions such as epilepsy, sleep disorders, or brain injuries.
  • The abnormal spike was clearly visible on the electroencephalograph, confirming the seizure activity.
