electrocorticography

[ ih-lek-troh-kawr-ti-kog-ruh-fee ]

noun

, Medicine/Medical.

1. a technique for surveying the electrical activity of the cerebral cortex by means of an electroencephalograph and electrodes attached to the brain.

Word History and Origins

Origin of electrocorticography¹

electro- + cortico- + -graphy

Example Sentences

Six theory-neutral labs would scan the brains of 250 total participants using three techniques: functional magnetic resonance imaging, magnetoencephalography, and electrocorticography, in which electrodes are placed on the brain’s surface prior to a surgery.

From Science Magazine

This July, researchers at the University of California funded by the social network showed decoding of a small set of full, spoken words and phrases from brain activity in real time for the first time – though it was done with so-called electrocorticography electrodes laid on the surface of the brain via surgery.

From The Guardian

Facebook’s approach relies on high-density electrocorticography, aka ECoG, which implants sensors on the brain and uses them to record brain activity.

From The Verge

Intracortical microelectrode arrays, for example, have generally led to higher performance than electrocorticography in other areas of BCI research3,7.

From Nature

The authors used a technique called high-density electrocorticography to track the activity of areas of the brain that control speech and articulator movement as the volunteers spoke several hundred sentences.
