Introduction
near infared radiation spectophotometry
Types:
- continuous wave near infrared spectroscopy (CW-NIRS)
- frequency domain near infrared spectroscopy (FD-NIRS)
Advantages
- can measure oxygenation and blood flow in tissues
- can effectively monitor cognitive tasks[3][6]
- attention
- working memory
- target categorization
- problem solving
- can be implemented as a wearable, minimally intrusive device[6]
Disadvantages
- CW NIRS studies have shown little difference in brain oxygenation of dead compared to live subjects[1]
