2 Channel, Near Infrared, Spectroscopy HEG Pendant POD including BioExplorer Software and Headset.

The Pendant-HEG is a lightweight unit that can hang around your neck. The battery attaches to the back of the pendant with hook and loop fasteners. The pendant connects to an HEG headband and sends the HEG (brain blood oxygenation) data to your computer via a wireless receiver.

Hershel Toomim's nIR system measures oxygenation of cerebral blood flow. The headband contains an optical sender and sensor.

Includes required nIR HEG headset and BioExplorer Software.

IMPORTANT NOTICE: This product is NOT FOR MEDICAL USE and is solely for PERSONAL USE. Not for use by children. Not for use by photosensitive epileptics.

An area of the brain that is more active will give off more heat and have greater blood flow and blood oxygenation than a brain area that is less active. The HEG headbands take advantage of these facts.

The nIR or near infrared headband, developed by Hershel Toomin, utilizes the fact that more highly oxygenated blood is redder in color. It sends pulses of red and infrared light through the skull to the cortex beneath. (The skull itself is not opaque but translucent.) By measuring the amount of red compared to infrared light that is reflected back by the cortex to the headband sensor, the headband can indicate how much oxygen there is in the blood. Because the light pulses take battery energy, the nIR headband uses more energy and has a lower battery life than the pIR headband.

The nIR headband can be placed at most locations on the skull. However, at hair covered areas, the hair needs to be parted and this can be a difficult skill to learn. The headband is typically used to train frontal areas.
