Ready to launch do target selective descending neurons prepare the dragonfly for prey pursuit
Meeting Abstract 116-3 Thursday, Jan. 7 10:45 Ready to launch: do target selective descending neurons prepare the dragonfly for prey pursuit? LIN, H-T*; LEONARDO, A; HHMI Janelia; HHMI Janelia linh10@janelia.hhmi.org Dragonflies are excellent aerial predators that capture flying insects on the wing. Their success hinges on both the prey pursuit strategy and the preparatory head tracking that […]
