Evaluation of hemodynamic response function during mental arithmetic task in fNIRS data using GLM method

To understand the complex structure of neural networks in the brain, which is a critical concept in Neuroscience, it is essential to identify different areas of the brain. Studies on the performance of various brain regions and their processing techniques have helped collect a large amount of data a...
