Davis has also worked on variety of chronic pain conditions, concussion, and phantom pain. She has demonstrated that findings support the hypothesis that the thalamic representation of the amputated limb remains functional in amputees with phantoms [8] Through several studies, she has shown important interactions between pain and cognition, by studying how brain networks shift their function towards pain while multitasking on cognitive tasks (Seminowicz et al., 2007; Erpelding et al., 2013) or when processing multimodal sensory information (Downar et al., 2000) or during mind wandering (Kucyi et al., 2013). She has introduced two influential theories that builds on the neuromatrix concept of Melzack.
