# 164 — Medial preoptic circuit induces hunting-like actions to target objects and prey

To determine which connections were responsible for mediating this behavior, Park et al trained mice to follow and engage with a colored cube “toy” in their environment. When the connections of MPA CaMKII$\alpha$ neurons to those in the ventral periaqueductal gray (vPAG) were stimulated, the mice engaged an order of magnitude more with the movable cube. When these neurons were not stimulated, the mice failed to show any more interest in the cube than usual.
