Primary Outcome Measures

Name	Time	Method
Electroencephalography (EEG) signals	Brain activity assessments are conducted as a single session lasting approximately 60 minutes.	Brainwaves are electrical currents generated when signals are transmitted between neurons in the nervous system. They vary depending on the mental and physical state of an individual and serve as one of the most critical indicators for measuring brain activity. Brainwaves can be recorded using devices such as electroencephalography (EEG), and in some cases, electrodes may be attached directly to the cortex. These devices are used to evaluate conditions such as brain damage, epilepsy, or other neurological disorders, as well as to legally determine brain death.

Secondary Outcome Measures

Name	Time	Method
Functional Near-Infrared Spectroscopy(fNIRS) signals	Brain activity assessments are conducted as a single session lasting approximately 60 minutes.	The near-infrared spectrum between 800 nm and 2500 nm is commonly used to measure changes in reflectance, absorbance, and scattering coefficients associated with specific processes involving molecules or ions. This allows for the assessment of parameters such as oxygen saturation, blood flow, glucose levels, and energy metabolism in the bloodstream by analyzing changes in the distribution of oxyhemoglobin and deoxyhemoglobin in areas like the fingers, wrists, and brain blood flow. In this study, it is specifically utilized to measure oxygen saturation in brain blood flow.
