Anesthesia enters the depth-psychology corpus along two distinct but often convergent axes. The first is the classical psychopathological axis, originating with Charcot and elaborated exhaustively by Pierre Janet, in which hysterical anesthesia designates not a pharmacological state but a dissociative suspension of sensory integration — a failure of 'personal perception' in which elementary sensations persist subcortically while failing to be assimilated into unified self-awareness. Janet's lectures demonstrate that this anesthesia is mobile, suggestible, and without anatomical coherence, marking it as a mental rather than neurological phenomenon. The second axis is the somatic-defensive axis, developed by Nijenhuis and informed by ethological models, in which anesthesia-analgesia constitutes a measurable somatoform dissociative symptom cluster strongly predictive of dissociative disorder and correlated with histories of physical and sexual abuse — understood as analogous to total submission responses in prey animals. A third, more clinical-philosophical axis appears in Damasio, who treats pharmacological anesthesia as a mechanism that distorts body-mapping and thereby suspends feeling and consciousness, and in Ferenczi, who connects narcotic anesthesia to patients' defensive avoidance of traumatic pain. Hillman contributes an archetypal-developmental counterpoint, reading the sensory diminishment of old age as a natural anesthesia that paradoxically intensifies imaginative acuity. Across these traditions, anesthesia functions as a privileged site for interrogating the relationship between sensation, consciousness, selfhood, and trauma.
hysterical anesthesia is a certain species of absent-mindedness... There is in it a pathological incapacity to collect the elementary sensations in a general perception.
Janet argues that hysterical anesthesia is not ordinary inattention but a specific pathological failure of synthesis, in which elementary sensations survive while their integration into personal consciousness is lost.

it is moreover this character which will enable us to arrive at a more intelligible conception of the paralysis itself... the mental character of this anesthesia.
Janet establishes the 'mental character' of hysterical anesthesia — its geometric, non-anatomical localization and psychological mobility — as the diagnostic key distinguishing hysteria from organic neurological lesion.

hysterical anesthesia certainly does not play in practice the absolutely pre-ponderant rôle that Charcot maintained it did... your manner of interrogating will create outright an an[esthesia].
Janet critically revises Charcot's overemphasis on anesthesia as the essential hysterical stigma, noting that its extreme mobility makes it as susceptible to iatrogenic production as to genuine clinical recognition.

total submission to the predator and total anesthesia after other defensive maneuvers failed or were inappropriate.
Nijenhuis frames total anesthesia as the terminal defensive response in a graduated ethological model, equating it with complete surrender when active and semi-active defenses are exhausted.

a stepwise logistic regression analysis was performed... yielded a regression equation with anesthesia-analgesia and urogenital pain.
Nijenhuis demonstrates empirically that anesthesia-analgesia, together with urogenital pain, constitutes the strongest predictive cluster for caseness of dissociative disorder in statistical modelling.

the remarkable mobility of these anesthesias. Unquestionably, some patients retain their s[ensibility].
Janet documents the clinical mobility of hysterical anesthesias — their tendency to shift, partially recover, or be transiently abolished — as a defining feature separating them from fixed organic insensibilities.

Anesthesia suspends the processes of sensing and responding. I believe that in complex creatures such as humans anesthesia suspends feelings and consciousness because feelings and consciousness depend on the general machinery of sensing and responding.
Damasio argues that pharmacological anesthesia is best understood not as the negation of consciousness per se but as the suspension of the sensing-and-responding machinery upon which feeling and consciousness depend.

this anesthesia of the old is so much taken for granted... The sensuous acuity remains, but has become detached from the senses. It is now more literary and less literal.
Hillman reframes age-related sensory decline as a form of anesthesia that paradoxically liberates imaginative and memorial intensity from literal sensory dependence.

She saw (visual anesthesia) and experienced 'holes' (organic anesthesia) where those members should have been... State-dependent anesthesia applied to other sensory modalities as well.
Nijenhuis illustrates through clinical case material how somatoform anesthesia in dissociative identity disorder operates across multiple sensory modalities in a state-dependent manner, distorting body schema.

A patient does not feel the electric current when he has his eyes shut. He acknowledges a tickling on seeing the manipulation of the process.
Janet demonstrates experimentally that hysterical anesthesia is attentionally modulated — sensory registration occurs subconsciously but fails to reach personal perception without directed attention.

One might also consider combining anesthesia with hypnotic suggestion... Case 3, O.S., is also so terrified of physical pain that she had acquired from Paris two hundred dollars worth of her own anesthetic equipment.
Ferenczi explores narcotic anesthesia as both a clinical technique for accessing traumatic material and as a symptom of patients' terror of physical and psychic pain, illustrating the defensive function of anesthesia-seeking.

'Anesthesia,' Burcq once said, 'exercises a preponderant influence on all the other symptoms, in particular on the disturbances of alimentation and on the secretions.'
Janet reviews the hypothesis that visceral and gastric anesthesia underlies hysterical anorexia, critically assessing Burcq's claim that anesthesia drives the full symptomatic picture of hysteria.

you will be able, in certain cases, to recognize a very special anesthesia relative to respiration itself. We feel our respiration, and, above all, we feel the need of breathing.
Janet extends the concept of hysterical anesthesia to interoceptive domains, identifying a specific respiratory anesthesia — the loss of the felt need to breathe — as among the more clinically significant visceral stigmata.

as a result of the administration of drugs that interfere with body signaling (painkillers, anesthetics), the brain receives a distorted view of what the body state really is at the moment.
Damasio frames anesthetic action as producing a hallucination of bodily state, wherein the brain's body maps are decoupled from physiological reality through pharmacological interference with signal transmission.

The stigma of anesthesia — The historical importance of this stigma — Its exaggeration — The two meanings of the word 'stigma'.
Janet situates hysterical anesthesia within the broader problematic of hysterical stigmata, tracing the historical inflation of its diagnostic importance and arguing for its proper conceptual delimitation.

what has disappeared is not the elementary sensation, the preservation of which we have just seen; it is the faculty that ena[bles personal perception].
Janet clarifies that hysterical anesthesia involves the loss of personal-perceptual synthesis rather than the destruction of elementary sensation, grounding the concept in his broader theory of psychological disaggregation.

analgesia and kinesthetic, visual, auditory, gustatory, and olfactory anesthesia (n = 11); freezing (n = 7).
Nijenhuis operationalizes anesthesia as a multi-modal somatoform dissociation cluster in the SDQ-20 instrument, grouping it with analgesia across kinesthetic, visual, auditory, gustatory, and olfactory channels.

anesthesia when it is connected with hysteria presents certain characters that are not to be found when the insensibility depends on organic affections of the nervous system.
Janet differentiates hysterical anesthesia from organic insensibility by its geometric, psychologically determined localization, establishing the clinical and conceptual boundary between neurological and dissociative anesthesia.

the lack of feeling and of will (abulia), and the inability to begin and end activities... Hysteria's 'proper stigmata' relate to the retraction of the field of consciousness.
Nijenhuis, following Janet, contextualizes anesthesia within the taxonomy of hysterical stigmata, linking it to retraction of the field of consciousness as a core dissociative mechanism.

the same patients may, in the same way, lose through dissociation a great and old system of thou[ghts and sensations].
Janet draws an analogy between the dissociation underlying somnambulism and that underlying hysterical anesthesia, positioning both as losses of organized sensorimotor-cognitive systems through disaggregation.

the lowering of the nervous strength produces, in some manner, a superficial retraction; ... with hystericals, in consequence of particular dispositions.
Janet locates hysterical anesthesia within his broader energetic model, as one consequence of lowered nervous tension producing selective retraction of psychological function in predisposed individuals.
