Next abstract Session Y3 - Biophysics of Prey Localization and Neuronal Timing. Sand scorpions, and many other arachnids, find their prey at night by localizing the source of mechanical waves produced by prey movements. This input opens a time window whose width determines the firing probability of each of the second-order neurons.
Stochastic resonance is realized through tuning the balance between excitation and inhibition.
The agreement with behavioral experiments on sand scorpions is excellent.
