Quantification of Planar Cortical Magnification with Optimal Transport and Topological Smoothing
Yujian Xiong, Negar Jalili Mallak, Yanshuai Tu +2
The human visual system exhibits non-uniform spatial resolution across the visual field, which is characterized by the cortical magnification factor (CMF) that reflects its anatomi…
Schrödinger Diffusion Driven Signal Recovery in 3T BOLD fMRI Using Unmatched 7T Observations
Yujian Xiong, Xuanzhao Dong, Sebastian Waz +4
Ultra-high-field (7 Tesla) BOLD fMRI offers exceptional detail in both spatial and temporal domains, along with robust signal-to-noise characteristics, making it a powerful modalit…
Enhancing 3T Retinotopic Maps Using Diffeomorphic Registration
Negar Jalili-Mallak, Yanshuai Tu, Zhong-Lin Lu +1
Retinotopic mapping aims to uncover the relationship between visual stimuli on the retina and neural responses on the visual cortical surface. This study advances retinotopic mappi…
Characterizing visual cortical magnification with topological smoothing and optimal transportation
Yujian Xiong, Yanshuai Tu, Zhong-Lin Lu +1
Human vision has different concentration on visual fields. Cortical magnification factor (CMF) is a popular measurement on visual acuity and cortex concentration. In order to achie…
Reconstructing Retinal Visual Images from 3T fMRI Data Enhanced by Unsupervised Learning
Yujian Xiong, Wenhui Zhu, Zhong-Lin Lu +1
The reconstruction of human visual inputs from brain activity, particularly through functional Magnetic Resonance Imaging (fMRI), holds promising avenues for unraveling the mechani…
Topological Receptive Field Model for Human Retinotopic Mapping
Yanshuai Tu, Duyan Ta, Zhong-Lin Lu +1
The mapping between visual inputs on the retina and neuronal activations in the visual cortex, i.e., retinotopic map, is an essential topic in vision science and neuroscience. Huma…
Optimizing Visual Cortex Parameterization with Error-Tolerant Teichmuller Map in Retinotopic Mapping
Yanshuai Tu, Duyan Ta, Zhong-Lin Lu +1
The mapping between the visual input on the retina to the cortical surface, i.e., retinotopic mapping, is an important topic in vision science and neuroscience. Human retinotopic m…
