Ocular dominance patterns in mammalian visual cortex: A wire length minimization approach [article]

Dmitri B. Chklovskii, Alexei A. Koulakov
1999 arXiv   pre-print
We propose a theory for ocular dominance (OD) patterns in mammalian primary visual cortex.  ...  Thus we can understand the existing OD patterns by solving a wire length minimization problem. We divide all the neurons into two classes: left-eye dominated and right-eye dominated.  ...  In conclusion, we explained the OD patterns in mammalian V1 by minimizing wire length given general functional considerations.  ...

A wire length minimization approach to ocular dominance patterns in mammalian visual cortex

Dmitri B Chklovskii, Alexei A Koulakov
2000 Physica A: Statistical Mechanics and its Applications  
Thus, the existing OD patterns are obtained by solving a wire length minimization problem. We divide all the neurons into two classes: right-and left-eye dominated.  ...  The primary visual area (V1) of the mammalian brain is a thin sheet of neurons. Because each neuron is dominated by either right or left eye one can treat V1 as a binary mixture of neurons.  ...  In conclusion, we explained the OD patterns in mammalian V1 by minimizing wire length given general functional considerations.  ...
