thermal imaging organ of pit vipers is a remarkable example for how biological systems integrate information from many noisy sensors into a collective response. Single nerve fibers innervating the organ robustly respond to milli-Kelvin changes in temperature,
even though the opening probability of each individual temperature-sensitive ion channel only changes by 0.1%. Here, we propose a mechanism for the integration of this noisy molecular information into an amplified response. Amplification arises due to proximity
to a dynamical bifurcation, separating a regime with frequent and regular firing of action potentials (APs), from one with irregular and infrequent firing. Near the transition, AP frequency can have an extremely sharp dependence on temperature, and most of
the information in molecular receptors is efficiently transmitted to AP firing even if additional noise corrupts the signal or readout. Our model explains several key features of experimental data. Most significantly, it predicts that the coefficient of variation
in the distribution of times between APs decreases for larger AP frequency. It also suggests that the intrinsic channel timescale may be slower than the timescale of the cell’s voltage dynamics, thereby leading to memory in the state of the channels.</span></p>

in using methods and tools of statistical mechanics, nonlinear dynamics, and information theory to describe and help understand biological phenomena. Her current research in Ben Machta’s group focuses on signal amplification and information integration in
biological sensory systems and on the phase behavior of mixtures with many components. Before joining Yale University, she was a PhD student in Physics in Erwin Frey’s group at LMU Munich, Germany, where she worked on collective dynamics and self-organization
in the context of the cell cytoskeleton and on non-equilibrium self-assembly of heterogeneous structures. </span></span><span style="font-size: 12pt; color: black;"></span></p>
