Complete structure of topographic maps in ephrin-A deficient mice
D. N. Tsigankov, A. A. Koulakov
Axons of retinal ganglion cells establish orderly projections to the superior colliculus of the midbrain. Axons of neighboring cells terminate proximally in the superior colliculus…
Can repulsion be induced by attraction: a role of ephrin-B1 in retinotectal mapping?
Dmitry N. Tsigankov, Alexei A. Koulakov
We study a role of EphB receptors and their ligand ephrin-B1 in dorsal-ventral retinotopic mapping. Earlier studies suggested that ephrin-B1 acts as an attractant for EphB expressi…
How to find decision makers in neural circuits?
Alexei A. Koulakov, Dmitry Rinberg, Dmitry N. Tsigankov
Neural circuits often face the problem of classifying stimuli into discrete groups and making decisions based on such classifications. Neurons of these circuits can be distinguishe…
Ocular dominance patterns and the wire length minimization: a numerical study
Alexei A. Koulakov, Dmitri B. Chklovskii
We study a mathematical model for ocular dominance patterns (ODPs) in primary visual cortex. This model is based on the premise that ODP is an adaptation to minimize the length of…
A stochastic model for retinocollicular map development
Alexei A. Koulakov, Dmitry N. Tsigankov
We present a theoretical model for retinocollicular map development, which can account for intriguing behaviors observed in gain-of-function experiments in knock-in mice by Brown e…
Instantons in the working memory: implications for schizophrenia
Alexei A. Koulakov
The influence of the synaptic channel properties on the stability of delayed activity maintained by recurrent neural network is studied. The duration of excitatory post-synaptic cu…
