Two symmetry breaking mechanisms for the development of orientation selectivity in a neural system
Myoung Won Cho
Orientation selectivity is a remarkable feature of the neurons located in the primary visual cortex. Provided that the visual neurons acquire orientation selectivity through activi…
General representation of collective neural dynamics with columnar modularity
Myoung Won Cho, Seunghwan Kim
We exhibit a mathematical framework to represent the neural dynamics at cortical level. Our description of neural dynamics with columnar and functional modularity, named fibre bund…
Instability of planar vortices in two-dimensional easy-plane Heisenberg model with distance-dependent interactions
Myoung Won Cho, Seunghwan Kim
It is known that magnetic vortices in two dimensional Heisenberg models with easy-plane anisotropy exhibit an instability depending on the anisotropy strength. In this paper, we st…
Different ocular dominance map formation by influence of orientation columns in visual cortices
Myoung Won Cho, Seunghwan Kim
In animal experiments, the observed orientation preference (OP) and ocular dominance (OD) columns in the visual cortex of the brain show various pattern types. Here, we show that t…
Understanding visual map formation through vortex dynamics of spin Hamiltonian models
Myoung Won Cho, Seunghwan Kim
The pattern formation in orientation and ocular dominance columns is one of the most investigated problems in the brain. From a known cortical structure, we build spin-like Hamilto…
