Methods: Suppose Ø:S1->S2 is a map from the surface S1 to the surface S2, we define the derivative map of Ø is the linear map between the tangent spaces, dØ:TM(p)->TM(Ø(p)), induced by the map. Let J be the derivative map and define the deformation tensor as S=(JTJ)1/2. Instead of analyzing shape change based on the eigenvalues of the deformation tensor, we consider a new family of metrics, the "Log-Euclidean metrics". Later on, we apply Hotelling's T2 test on the log-Euclidean space of the deformation tensors.

We recently found that direct stimulation of visual cortex using TMS could result in phosphenes that extended outside the visual field (Wu et al, VSS 2006). Brightness was perceived to emanate from positions inside the mouth, beneath the head, or even behind the ear. Though previous studies using retinal stimulation had failed to produce similar results (Hayhoe & Williams 1984, Cavanagh & Barto...

Introduction Using Diffusion Tensor Imaging (DTI) sequence provided by magnetic resonance imaging system, the diffusion properties of water can be quantified by measuring the diffusion anisotropy within each voxel [1]. Thus, one is able to track axons in white matter since their diffusivity is significantly higher than that of the rest of the tissue. The aim of this work is to use DTI to assess...

The theoretical vertical horopter is a line passing through the fixation point and perpendicular to the horizontal plane, when the fixation is symmetric and on the horizontal median plane. However, the empirical vertical horopter measured psychophysically deviates from the true vertical, as its top inclines backward with an angle. Thus the two corresponding retinal images of the empirical verti...

Introduction: The process of aging is essentially defined by a decline in various physical and mental processes that take place within the human body. Healthy aging is not only accompanied by a decline in cognitive processing, but also motor function, in particular an increase in the slowness of movements and a loss of coordination. Functional brain imaging has indicated that age-related change...
