In recent years, functional neuroimaging has disclosed a network of cortical areas in the basal temporal lobe that selectively respond to visual scenes, including the parahippocampal place area (PPA). Beyond the observation that lesions involving the

Euler angles play a vital role in diffusion tensor imaging (DTI) which has received intensive attention recently. However, different Euler angle conventions generate different rotation paths, whereas in some applications it is desirable to obtain a u
