# gst: (you must) read the noise as a message
<< Noise is often thought to be a nuisance with negative consequences, (..) But through this study we show that noise can actually be used as a salient informational cue. It can provide individuals with important information about their environment and when it's safe to hunt. >> Inga Geipel

<< Background noise can have strong negative consequences for animals, reducing individual fitness by masking communication signals, impeding prey detection and increasing predation risk. While the negative impacts of noise across taxa have been well documented, the use of noise as an informational cue, providing animals with reliable information on environmental conditions, has been less well studied. >>

# gst: the hypothesis to optimize multiplicative noise to enhance a signal-to-noise ratio
AA << study simple integrate-and-fire type models with multiplicative noise and consider the transmission of a weak and slow signal, >>
<< The specific question of interest is whether and how the state-dependence of the noise can be optimized with respect to information transmission >>
<< also in a biophysically more relevant situation, multiplicative noise can enhance the signal-to-noise ratio (..) results shed light on a so far unexplored aspect of stochastic signal transmission in neural systems. >>
