Localizing Retinotopic fMRI Activation in Human Primary Visual Cortex via Dynamic Programming

This paper presents an approach for automatically delineating the borders of human primary visual cortex and finding ridges of maximal response due to static phase-encoding stimuli on fMRI t-statistical maps via dynamic programming. The sensitivity of such an approach to the choice of initial starting and ending points and the identification of the ridge path over a wide response region are addressed. Moreover, retinotopic maps for left and right visual cortex are shown in a population of two normal subjects
