Within the depth-psychology and embodied-mind corpus, 'limb' functions less as an anatomical datum than as a nexus for investigating the relationship between bodily integrity, self-representation, and psychic identity. The term arrives with greatest theoretical force through the phenomenon of the phantom limb, which commands sustained attention from Merleau-Ponty, Gallagher, Damasio, Sacks, and Fogel. Each deploys the phantom as evidence for a constitutive claim: that the body schema or body image is not derived purely from peripheral sensation but possesses an irreducibly central — and, on some accounts, innate — organization. Merleau-Ponty reads the phantom as exposing the ontological ambiguity of embodied existence, where presence and absence resist neat categorical separation; the anosognosic and the amputee both testify to a pre-reflective investment in bodily wholeness. Gallagher pushes further, using aplasic phantoms to argue for an innate body schema antecedent to all experience. Damasio interprets phantom phenomena through dispositional representations that persist in the absence of on-line peripheral input. McGilchrist, meanwhile, situates limb-ownership disturbances — misoplegia, somatoparaphrenia, supernumerary phantoms — within hemispheric asymmetry. Across these traditions, the limb functions as the site where neuroscience, phenomenology, and depth psychology converge on questions of selfhood, loss, and the integrity of the lived body.

An emotion or circumstance, which recalls those in which the wound was received, creates a phantom limb in subjects who had none. It happens that the imaginary arm is enormous after the operation, but that it subsequently shrinks and is absorbed into the stump 'as the patient consents to accept his mutilation'.
Merleau-Ponty argues that the phantom limb is governed by psychic and existential determinants — emotion, memory, and the patient's acceptance of loss — rather than by peripheral or purely cerebral mechanisms alone.
Merleau-Ponty, Maurice, Phenomenology of Perception, 1962thesis
In reality the anosognosic is not simply ignorant of the existence of his paralysed limb: he can evade his deficiency only because he knows where he risks encountering it, just as the subject, in psychoanalysis, knows what he does not want to face.
Merleau-Ponty draws a structural parallel between anosognosia regarding a paralysed limb and psychoanalytic repression, establishing the body's absence as an object of pre-conscious avoidance rather than mere ignorance.
Merleau-Ponty, Maurice, Phenomenology of Perception, 1962thesis
if a body schema is something that is acquired only over the course of experience (in the first 8-12 months of life) then an aplasic phantom is just as impossible as neonate imitation. On the other hand, if a body schema is innate in the right way, then it should be quite possible to find cases of aplasic phantoms.
Gallagher uses congenital absence of limb and its associated phantom phenomena as the decisive test case for whether the body schema is innate or acquired through experience.

Implicit in the representation of the motor possibilities of the mouth, there must be a representation of the missing limb as well — enough, at least, so it 'closes the circuit' (by opening the mouth in anticipation) and completes the coordinated mouth-limb schema. Activating the circuit generates a virtual or phantom limb.
Gallagher proposes that aplasic phantom limbs arise from an innate hand-mouth motor circuit whose neural representation of the absent limb persists as a structurally necessary component of feeding-related coordination.
Gallagher, Shaun, How the Body Shapes the Mind, 2005thesis
My interpretation of this phenomenon is that in the absence of on-line input from the missing limb, there prevails the on-line input from a dispositional representation of that limb: that is, the reconstruction through the process of recall of a previously acquired memory.
Damasio interprets the phantom limb as the brain's activation of a stored dispositional representation of the absent body part in the absence of current sensory input, grounding the phenomenon in memory rather than peripheral deception.

When 'Philip' saw his reflected limb in the place of the phantom, he was elated and said, 'My left arm is plugged in again. It's as if I'm in the past. All these movements from many years ago are flooding back into my mind.'
Fogel reports Ramachandran's mirror-box treatment, in which visual substitution for the phantom limb unlocked stored motor memories and ultimately dissolved both the phantom and its associated pain.

Weir Mitchell described several sorts of phantom — some strangely ghost-like and unreal; some compellingly, even dangerously, lifelike and real; some intensely painful, others quite painless; some photographically exact, like replicas or facsimiles of the lost limb, others grotesquely foreshortened or distorted.
Sacks surveys the typology of phantom limb experience established by Weir Mitchell, foregrounding the full phenomenological range from uncanny absence to hyperreal presence, and noting the dual central and peripheral determinants of these body-image disorders.

Some have somatoparaphrenia, denying the paralysed limb belongs to them, believing it to belong to someone else. She has drawn her daughter's skirt and legs in the place where her hand should be.
Mizen documents how neurological damage to the right hemisphere can produce radical alienation from one's own limb — somatoparaphrenia — in which the paralysed limb is re-attributed to another person, dissolving the boundary between self and other at the level of the body.

another had at times up to six supernumerary phantom limbs after a right middle cerebral artery infarct: 'the patient's adamant and delusional conviction of their reality caused him considerable distress'.
McGilchrist marshals neurological case evidence to show that right hemisphere damage can generate not merely absent but supernumerary phantom limbs, arguing for the hemisphere's role in constituting a coherent and bounded body schema.

let us suppose you cut a developing limb bud out of an amphibian embryo, shake the cells loose from each other, and then allow them to aggregate once more into a random lump. You then replace the random lump in the embryo. What happens? A normal leg develops.
McGilchrist uses embryological limb-bud regeneration to argue that morphogenetic wholeness is a property of the organism as a whole, with the form of the limb guiding the reorganization of its constitutive cells — an argument against purely mechanistic part-to-whole explanations.

Lacking experiential reinforcement they deteriorate to some degree, and are displaced or dominated by neighboring neurons, stimulation of which can generate phantom limb experience.
Gallagher's second hypothesis on aplasic phantoms holds that genetically specified neural representations of the absent limb, deprived of movement-based reinforcement, undergo cortical reorganization whose stimulation yields phantom experience.

Simmel's data, based on interviews in which subjects were explicitly asked to describe their perceived phantom, show that the phantom is an 'exp[erienced percept]'... what Katz (1993: 151) terms the 'phantom limb percept'.
Gallagher critiques Simmel's conflation of body schema and body image in the context of aplasic phantoms, arguing that the evidence actually supports the phantom as a body-image percept rather than a purely schematic phenomenon.

Proprioception is the bodily sense that allows us to know how our body and limbs are positioned. If a person with normal proprioception is asked to sit, close his eyes, and point to his knee, it is proprioception that allows him to successfully guide his hand and find his knee.
Gallagher uses Ian Waterman's deafferentation to demonstrate that proprioception is the foundational mechanism by which the subject maintains real-time awareness of limb position, and that its loss necessitates conscious cognitive substitution.

in the case of the aplasic limb, the proprioceptive experience that develops along with the initiated coordinated movement finds no fulfillment or reinforcement in the modality of touch (contact of mouth with
Gallagher argues that in aplasia the proprioceptive component of hand-mouth coordination initiates without the tactile fulfillment that would normally reinforce it, resulting in a degraded but residual neural representation available as phantom experience.

The loss of one's health, the loss of a limb or one's sight — all these are losses of function, but are also experienced as losses of part of who you are.
O'Connor frames limb loss within the neuroscience of grief, arguing that the loss of a limb constitutes not merely a functional deficit but an identity loss that activates the same neurochemical grief responses evolved for bereavement.

Snell establishes that Homeric Greek possessed no unified concept of 'body,' using only plural terms for limbs and members to designate physical corporeality, reflecting a pre-unified, aggregative conception of the human form.

it is precisely what allows the limbs to be substituted for each other, and to be of equal value before the self-evident demands of the task.
Merleau-Ponty describes how the body schema's motor intentionality renders individual limbs functionally interchangeable in task-oriented action, subordinating anatomical specificity to the primacy of the task.
