Universal properties of concentration sensing in large ligand-receptor networks
Vijay Singh, Ilya Nemenman
Cells estimate concentrations of chemical ligands in their environment using a limited set of receptors. Recent work has shown that the temporal sequence of binding and unbinding e…
What the odor is not: Estimation by elimination
Vijay Singh, Martin Tchernookov, Vijay Balasubramanian
Olfactory systems use a small number of broadly sensitive receptors to combinatorially encode a vast number of odors. We propose a method of decoding such distributed representatio…
A competitive binding model predicts nonlinear responses of olfactory receptors to complex mixtures
Vijay Singh, Nicolle R. Murphy, Vijay Balasubramanian +1
In color vision, the quantitative rules for mixing lights to make a target color are well understood. By contrast, the rules for mixing odorants to make a target odor remain elusiv…
Extrinsic and intrinsic correlations in molecular information transmission
Vijay Singh, Martin Tchernookov, Ilya Nemenman
Cells measure concentrations of external ligands by capturing ligand molecules with cell surface receptors. The numbers of molecules captured by different receptors co-vary because…
Accurate sensing of multiple ligands with a single receptor
Vijay Singh, Ilya Nemenman
Cells use surface receptors to estimate the concentration of external ligands. Limits on the accuracy of such estimations have been well studied for pairs of ligand and receptor sp…
Director Field Model of the Primary Visual Cortex for Contour Detection
Vijay Singh, Martin Tchernookov, Rebecca Butterfield +1
We aim to build the simplest possible model capable of detecting long, noisy contours in a cluttered visual scene. For this, we model the neural dynamics in the primate primary vis…
