Modifying the feedforward transmission of information is an important mechanism by which the nervous system filters sensory inputs to preference one behaviour over another. The superior colliculus mediates visually guided behaviours via cell-type specific projections. However, how the retinal and brain-wide inputs to the superior colliculus are organized to influence visual processing and behaviour remains poorly described. Here I will discuss our labs work using large scale anatomical and functional circuit tracing techniques to dissect circuit motifs within the superior colliculus that enable the fast, reliable, yet flexible triggering of innate defensive behaviours in response to visual treats.
