Homogeneous V1–LGN connectivity conjecture. This reconstruction step is accomplished by the action of the connectivity between V1 and the lateral geniculate nucleus (LGN) in a homo…

Let $Q$ be the five-dimensional sub-Riemannian geometry modeling orientation-, frequency-, and phase-selective simple cells in the primary visual cortex $V1$, with horizontal vecto…

Let $\mathcal{M}$ be the model's five-dimensional lifted feature space, whose points encode position, orientation, phase and frequency, and let the horizontal distribution define t…

Topological obstruction conjecture. There are topological constraints that prevent the possibility of detecting a continuum of directions even when the distance between pinwheels t…
