Hemoencephalography

Hemoencephalography (pronunciation: he-mo-en-ce-phal-og-raphy) is a type of neurofeedback technique that measures changes in the blood oxygen levels in the brain. The term is derived from the Greek words 'haima' meaning blood, 'enkephalos' meaning brain, and 'graphein' meaning to write.

History

Hemoencephalography was first introduced in the late 1990s by a team of researchers led by Dr. Hershel Toomim. The technique was developed as a non-invasive method to monitor the blood flow in the brain and provide real-time feedback to the patient.

Method

Hemoencephalography uses near-infrared spectroscopy (NIRS) to measure changes in the blood oxygen levels in the brain. The technique involves shining a light into the scalp and measuring the amount of light that is absorbed by the blood. The more oxygenated the blood, the more light it absorbs.

Applications

Hemoencephalography has been used in a variety of medical and psychological applications. It has been used to treat conditions such as attention deficit hyperactivity disorder (ADHD), anxiety, and depression. It has also been used in research to study the effects of meditation and other relaxation techniques on the brain.
