Mean HRF for vision and motor regions extracted from fMRI data with applying MDL denoising

a Mean HRF due to averaging in vision region (with applying MDL denoising)

b Mean HRF due to averaging in motor region (with applying MDL denoising)

c Mean HRF obtained from deconvolution in vision region (with applying MDL denoising)

d Mean HRF obtained from deconvolution in motor region (with applying MDL denoising). Error bars represent ±1 SEM. The black, green and red solid lines are associated with the mean HRF for the young, non-demented and demented elderly adults, respectively
