Patients with the neurological syndrome known as body integrity dysphoria express a desire to amputate seemingly healthy parts of their body. A new study has found that this condition is linked to altered functional connectivity in a distributed neural network underlying body image. 
White Matter Abnormalities in Body Integrity Dysphoria
TLDR
Previous results showing alterations in areas tuned to the processing of the sensorimotor representations of the affected leg, and to higher-order components of bodily representation such as the body image showed structural alterations as well are confirmed. Expand
White Matter Abnormalities in Body Integrity Dysphoria
TLDR
Previous results showing alterations in areas tuned to the processing of the sensorimotor representations of the affected leg, and to higher-order components of bodily representation such as the body image were confirmed and extended. Expand
When having a limb means feeling overcomplete. Xenomelia, the chronic sense of disownership and the right parietal lobe hypothesis
TLDR
The presence of both structural and functional multi-layered brain abnormalities in xenomelia suggests a multifactorial aetiology; however, as the prevalence of correlational studies, causal relationships remain to be investigated. Expand

The Desire for Amputation or Paralyzation: Evidence for Structural Brain Anomalies in Body Integrity Identity Disorder (BIID)
TLDR
The results suggest that BIID is associated with structural brain anomalies and might result from a dysfunction in the integration of multisensory information, leading to the feeling of disunity between the mental and physical body shape. Expand
Neural Correlates of Body Integrity Dysphoria
TLDR
The findings illustrate the pivotal role of the connectivity of the primary sensorimotor limb area in the mediation of the feeling of body ownership and delineate the morphometric and functional alterations in areas of higher-order body representation possibly responsible for the dissatisfaction with a standard body configuration. Expand
The desire for healthy limb amputation: structural brain correlates and clinical features of xenomelia.
TLDR
The predominantly right-sided cortical abnormalities are in line with a strong bias for left-sided limbs as the target of the amputation desire, evident both in this sample and in previously described populations with xenomelia. Expand
Limb amputation and other disability desires as a medical condition.
TLDR
This Review integrates research findings about the desire for a major limb amputation or paralysis (xenomelia) and suggests that disability desires are accompanied by a disabling bodily dysphoria, in many respects similar to gender dysphoria and should be considered a mental disorder. Expand
Neural Basis of Limb Ownership in Individuals with Body Integrity Identity Disorder
TLDR
Compared brain activation between limbs that do and do not feel as part of the body using functional MRI suggests that altered somatosensory processing in the premotor cortex is associated with the feeling of disownership in BIID, which may be related to altered integration of somatosensing and proprioceptive information.

Neural mechanisms of embodiment: asomatognosia due to premotor cortex damage.
TLDR
A patient with asomatognosia of her left arm was associated with mild left somatosensory loss, mild frontal dysfunction, and a behavioral deficit in the mental imagery of human arms. Expand
Somatoparaphrenia: a body delusion. A review of the neuropsychological literature
TLDR
Somatoparaphrenia is often brought about by extensive right-sided lesions, but patients with posterior (parietal-temporal), and insular damage are on record, as well as a few patients with subcortical lesions. Expand
The body in the brain: neural bases of corporeal awareness
TLDR
Dynamic aspects of the body schema are revealed by spontaneous sensations from a lost body part as well as by orderly phantom sensations elicited by stimulation of body areas away from the amputation line and even by visual stimulation. Expand
Xenomelia: a new right parietal lobe syndrome
TLDR
The authors propose that inadequate activation of the right SPL leads to the unnatural situation in which the sufferers can feel the limb in question being touched without it actually incorporating into their body image, with a resulting desire for amputation. Expand
The perception of phantom limbs. The D. O. Hebb lecture.
TLDR
It is suggested that patients with phantom limbs provide a valuable opportunity not only for exploring neural plasticity in the adult human brain but also for understanding the relationship between the activity of sensory neurons and conscious experience. Expand
