Description
Technical Field
The invention relates to the technical field of near infrared spectroscopy, in particular to a near infrared spectroscopy device capable of being worn on a head.
Background
Neurofeedback settings are assessed by visual light placed on the participant's head, covering a certain brain region, and are fed back to the subject, usually in the form of a visual representation. The individual can then use this feedback information to learn the successful self-regulation of brain activity and ideally transfer this skill into everyday life.
Some studies have shown that humans can modulate hemodynamic signals from cortical brain regions through neurofeedback in the near infrared spectrum, and these studies have shown that during neurofeedback training, participants are trained to self-regulate their brain activity with the goal of changing behavioral or cognitive/emotional functions. Study participants included stroke patients, hyperactivity or autism children, and anxiety patients.
Near infrared spectroscopy estimates hemoglobin concentration from changes in near infrared light absorption. As light moves or propagates in the head, it is alternately scattered or absorbed by the tissue through which it passes. Since hemoglobin is an important absorber of near-infrared light, changes in absorbed light can be used to reliably measure changes in hemoglobin concentration.
Different near infrared spectroscopy techniques can also use light propagation to estimate blood volume and oxygenation and can measure changes in regional oxygen and deoxyhemoglobin concentrations near the surface of the cortex.
The technique is safe, non-invasive, and can be used with other imaging modalities. As with electroencephalography, near infrared spectroscopy is one of the most common non-invasive neuroimaging techniques.
Most devices in current use are relatively bulky and have limited use in laboratory laboratories, and relatively few devices may be wearable and wireless.
Recently, some overseas companies, such as newbran and Obelab, have developed a wearable system that can wirelessly transmit hemodynamic neuromonitoring data to an external device. NewmanBrain was developed by a Spanish company and consisted of 28 channels weighing 290 g. ObelabnIRSIT was developed by a Korean company and weighed 550 g. The mass is heavy and the carrying is inconvenient.
