+Our scientific understanding of sensory processing systems results from the
+distributed accumulation of anatomical, physiological and ethological evidence.
+This process is undoubtedly without alternative; however, it leaves us with the
+challenge of integrating the available fragments into a coherent whole in order
+to address issues such as the interaction between individual system components,
+the functional limitations of the system overall, or taxonomic comparisons of
+systems that process the same sensory modality. Any unified framework that
+captures the essential functional aspects of a given sensory system thus has
+the potential to deepen our current understanding and fasciliate systematic
+investigations. However, building such a framework is a challenging task. It
+requires a wealth of existing knowledge, a clearly defined scope, and careful
+reduction, abstraction, and formalization of the underlying anatomical
+structures and physiological mechanisms.
+
+The auditory system of grasshoppers provides an excellent case study for

+One such sensory system that has been studied extensively over the course of
+decades is the auditory system of grasshoppers~(\textit{Acrididae}).
