The homuncular jigsaw: investigations of phantom limb and body awareness following brachial plexus block or avulsion [PDF]
, 2019 Many neuropsychological theories agree that the brain maintains a relatively persistent representation of one's own body, as indicated by vivid "phantom" experiences.

Etiology of phantom limb syndrome: Insights from a 3D default space consciousness model [PDF]
, 2015 In this article, we examine phantom limb syndrome to gain insights into how the brain functions as the mind and how consciousness arises. We further explore our previously proposed consciousness model in which consciousness and body schema arise when ...

The Gray filtration on phantom maps [PDF]
Fundamenta Mathematicae, 2001 In this well written and interesting paper, the authors study the Gray index of phantom maps. They introduce a new definition of the Gray index which immediately shows its homotopy invariance and allows them to study naturality properties of the index. This allows them to generalize a theorem of McGibbon and Roitberg on surjectivity of induced maps on ...

Thermoacoustic concentration imaging of magnetic nanoparticles under single-pulse magnetic fields
AIP Advances, 2022 Under a single-pulse magnetic field (SMF), we proposed a thermoacoustic (TA) concentration imaging method of magnetic nanoparticles (MNPs). This method derived the relationship between the concentration of MNPs and TA signals based on the mechanism of ...
