SIT - Sensory Island Task

A New Behavioral Paradigm to Study Sensory Perception and Neural Processing in Freely Moving Animals

This blog post is about SIT, a behavioral paradigm we recently published. In SIT, animals explore an open field arena to find a hidden target. For target detection, they rely solely on changes in the presented stimulus, which is controlled by closed-loop position tracking in real-time. The blog will mostly cover the application of SIT for acoustic discrimination training in mouse lemurs.
