Phantom limbs and the body schema.
AMPUTATED LIMBS persist as "phantoms" in their owners' consciousness. Temporary or permanent severance of afferent pathways may also give rise to subjective experiences in which the position of the phantom limb is different from that of the real one. Attempts have been made to explain phantom phenomena as expressions of a "body image" or "body schema" subserving a preconscious neurophysiologica...

متن کاملPhantom limbs and neural plasticity.
The study of phantom limbs has received tremendous impetus from recent studies linking changes in cortical topography with perceptual experience. Systematic psychophysical testing and functional imaging studies on patients with phantom limbs provide 2 unique opportunities. First, they allow us to demonstrate neural plasticity in the adult human brain. Second, by tracking perceptual changes (suc...
متن کاملPsychophysiological contributions to phantom limbs.
Recent studies of amputees reveal a remarkable diversity in the qualities of experiences that define the phantom limb, whether painless or painful. This paper selectively reviews evidence of peripheral, central and psychological processes that trigger or modulate a variety of phantom limb experiences. The data show that pain experienced prior to amputation may persist in the form of a somatosen...
متن کاملBeyond body experiences: phantom limbs, pain and the locus of sensation.
Reports of perceptual experiences are found throughout history. However, the phenomena considered worthy of note have not been those that nurture our survival (the veridical features of perception) but the oddities or departures from the common and commonplace accuracies of perception. Some oddities (like afterimages) could be experienced by everyone, whereas others were idiosyncratic. Such phe...
