Abstract

Human cognition is the essential building block of human intelligence, and it is what makes us who we are. Cognition is defined as the capacity to recognize and respond appropriately to external stimuli based on one’s beliefs, actions, experiences, and senses. It is one of the fundamental reasons for human existence and is one of the most important aspects of the brain. In childhood, adolescence, and maturity, the cognitive processes of humans are always evolving and developing. Although some of these abilities begin to diminish as one grows older and approaches older maturity, others begin to deteriorate when neurons die and the systems that replace them become insufficient. Understanding cognition is essential not just for healthy cognitive growth and survival but also for the treatment of a variety of neuropsychological conditions, such as Alzheimer’s disease. It is necessary to examine the cognitive functions of the human brain before one can comprehend cognition. fNIRS and electroencephalography (EEG) are low-cost methods of assessing and evaluating cognitive function. The principles of electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS), as well as a number of methods for preprocessing and interpreting EEG and fNIRS data, are therefore covered in this chapter. Lastly, the use of simultaneous EEG-fNIRS is discussed along with its limitations and advantages.
