Investigation of the Hemodynamic Response in Near Infrared Spectroscopy Data Analysis von Le Hoa Nguyen, Keum-Shik Hong

“… In this paper, a deconvolution algorithm to estimate the HRF is presented. The advantage of this method is no prior hypothesis about the shape of the HRF is required. In addition, in order to increase the sensitivity of NIRS to functional brain activity, an adaptive filter is designed to remove physiological noises from the noisy NIRS data. In order to verify the effectiveness of the proposed methods, numerical simulations were performed, the results of which are provided herein …”
