To demonstrate the feasibility of whole-brain multidimensional T_1_-T_2_ relaxation imaging on a portable 0.064 T MRI scanner. A two-dimensional inversion-recovery, fast spin-echo acquisition was used to jointly encode T_1_ and T_2_ relaxation. Joint relaxation distributions were reconstructed voxel-wise using…

Biological transport networks range from tree-like to highly reticulated architectures, which have been proposed to reflect different balances between viscous dissipation and metabolic cost. This balance cannot currently be inferred from structure: available descriptors either discard edge width entirely or preserve it…

Biological information is generally thought to be subject to selection for faithful maintenance. However, accurate preservation is often combined with regulated mechanisms that generate state change. Selectively advantageous instability (SAI) is modeled here as instability that is favored because useful alternatives…

Extensive studies suggest the brain performs Bayesian inference to infer the latent world states. It is a fundamental neuroscience question that how canonical recurrent neural circuits in the brain implement Bayesian inference. Many existing theoretical studies focused on how the recurrent circuits compute the…
