Unlike the DT [diffusion tensor] model, FBA relies on a spherical harmonic representation of diffusion that can more readily represent complex multi-fiber geometry, allowing for anatomically-informative metrics to be separately estimated for distinct fiber populations within a voxel. Specifically, fixel-based analysis utilizes constrained spherical deconvolution(CSD) to estimate fiber orientation distribution functions(fODFs) within each voxel, and then segments fODFs into directionally distinct lobes associated with distinct fiber populations("fixels") within a voxel. 2, record 1, English, - fixel%2Dbased%20analysis

In the last decades, imaging membrane potential has become a fruitful approach to study neural circuits, especially in invertebrate preparations with large, resilient neurons. At the same time, particularly in mammalian preparations, voltage imaging methods suffer from poor signal to noise and secondary side effects, and they fall short of providing single-cell resolution when imaging of the activity of neuronal populations. As an introduction to these techniques, we briefly review different voltage imaging methods(including organic fluorophores, SHG [second harmonic generation] chromophores, genetic indicators, hybrid, nanoparticles, and intrinsic approaches) and illustrate some of their applications to neuronal biophysics and mammalian circuit analysis. 1, record 2, English, - voltage%20imaging

Les neurobiologistes ont besoin de moyens plus efficaces et moins invasifs pour observer les circuits cérébraux, où des signaux électriques passent d'un neurone à l'autre. [...] Imagerie de voltage. Dans cette technique, on implante un colorant au sein du neurone afin de déterminer si la cellule est active. Il constitue un capteur, qui émet une fluorescence lorsque le champ électrique à travers la membrane cellulaire change de polarité; cela se produit quand un signal électrique passe. 2, record 2, French, - imagerie%20de%20tension

The Canadian Geomagnetic Reference Field(CGRF) is a mathematical model of the geomagnetic field over Canada. It is produced by carrying out a spherical cap harmonic analysis on numerous observations of the magnetic field made on the ground, at sea, in the air, and a satellite altitudes between 1960 and 1994. The latest CGRF is for 1995, but contains time terms that enable it to be used over the time interval 1960 to 2000. 1, record 7, English, - Canadian%20Geomagnetic%20Reference%20Field
