摘要：

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 or 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.
