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 they depend on the same extrinsic ligand fluctuations. However, these numbers also counter-vary due to the intrinsic stochasticity of chemical processes because a single molecule randomly captured by a receptor cannot be captured by another. Such structure of receptor correlations is generally believed to lead to an…

Receptor crosstalk improves concentration sensing of multiple ligands

It is demonstrated that crosstalk can improve precision in concentration sensing and discrimination tasks and is presented a proofreading scheme to realize an approximate estimation of multiple ligand concentrations that reaches a precision close to the derived optimal bounds.

Maximum Likelihood Detection With Ligand Receptors for Diffusion-Based Molecular Communications in Internet of Bio-Nano Things

A Maximum Likelihood (ML) detection method based on instantaneous receptor occupation ratio, as aligned with the current MC literature is introduced and a novel ML detection technique is proposed, which exploits the amount of time the receptors stay unbound in an observation time window.

Energy consumption and cooperation for optimal sensing

It is reported that in general the optimal sensing strategy depends both on the noise level and the statistics of the signals, and that energy consumption is not always required for optimal sensing.

Transmitter and Receiver Architectures for Molecular Communications: A Survey on Physical Design With Modulation, Coding, and Detection Techniques

This comprehensive survey of the existing literature on transmitter and receiver architectures toward realizing molecular communications among nanomaterial-based nanomachines and/or biological entities is reviewed and provides a complete overview of modulation, coding, and detection techniques employed for MC.

Coherence-Based Coding in Spiking Neural Network with Global Inhibitory Feedback

It is indicated that inhibitory feedback that controls the firing state of postsynaptic neurons can be significant in altering the network coding property, and the transmission time of inhibitory synapses also plays a key role in modulating the coherence.

Simple biochemical networks allow accurate sensing of multiple ligands with a single receptor

It is argued that structural and functional features of real cellular biochemical sensory networks in immune cells, such as feedforward and feedback loops or ligand antagonism, sometimes can be understood as solutions to the accurate multi-ligand estimation problem.

Neural Computation

The nervous system is able to develop by combining on one hand a only limited amount of genetic information and, on the other hand, the input it receives, and it might be possible to develop a brain from there.

A Mathematical Theory of Communication

It is proved that the authors can get some positive data rate that has the same small error probability and also there is an upper bound of the data rate, which means they cannot achieve the data rates with any encoding scheme that has small enough error probability over the upper bound.
