Information processing by the ‘probrain’: how bacteria sense and respond to chemicals

Despite their minuscule size, bacteria achieve feats of engineering with impressive evolutionary designs. This interest has also translated into a number of seminal theoretical works. In 1977, Howard Berg and Edward Purcell viewed the cell as a small measuring device, and estimated its sensing accuracy from molecular diffusion. In 1999, Tom Duke and Dennis Bray wondered how cells achieve their high sensitivity to detect small changes in stimuli, and considered Ising-like receptor cluster models to explain signal amplification. More recently, the development of new measurement technologies such as in vivo FRET and super-resolution imaging led to a renaissance in modelling efforts to describe signal amplification, integration, and precise adaptation, as well as information flow in the pathway from receptors to flagellated rotary motors. In this talk, I will describe my own explorations of bacterial chemo-sensing, with a number of fundamental unsolved problems remaining. Solving these questions will further our understanding of host-pathogen infections and aid the design of novel high-sensitivity biosensors.
