Emotional Experience and Awareness of Self: Functional MRI Studies of Depersonalization Disorder
Responses to emotive visual stimuli are explored to examine the functional neuroanatomy of emotional processing in DPD before and after pharmacological treatment and an area of right ventrolateral prefrontal cortex emerged as particularly implicated in what may be “top-down” inhibition of emotional responses.
Towards Decoding of Depersonalisation Disorder Using EEG: A Time Series Analysis Using CDTW
It was shown that DPD symptoms could be as a result of impairment in early (implicit) stages of information processing in the brain, and P45 was introduced as a potential electrophysiological biomarker to study DPD.
Uncomfortably numb: new evidence for suppressed emotional reactivity in response to body-threats in those predisposed to sub-clinical dissociative experiences
The present findings significantly extend previous research by revealing emotional suppression via a more direct body-threat task, even for sub-clinical groups, within probabilistic and predictive coding frameworks of multi-sensory integration underlying a coherent sense of self.

A flood of new multidisciplinary work on the causes of depersonalization disorder (DPD) provides a new way to think about the feeling that experiences “belong” to the self. In this paper I argue that
Assessing responsiveness to direct verbal suggestions in depersonalization-derealization disorder
The dissociative disorders and germane conditions are reliably characterized by elevated responsiveness to direct verbal suggestions. However, it remains unclear whether atypical responsiveness to
Deliberate and spontaneous sensations of disembodiment: capacity or flaw?
It is concluded that OBE should be regarded as a necessary implication of VPT ability in humans, or even as anecessary and potentially sufficient condition for the evolution of V PT.
The Detached Self: Investigating the Effect of Depersonalisation on Self-Bias in the Visual Remapping of Touch.
Results indicate disrupted integration of tactile and visual representations of the bodily self in those experiencing high levels of DP and provide greater understanding of how disruptions in multisensory perception of the self may underlie the phenomenology of depersonalisation.
Phenomenal depth: A common phenomenological dimension in depression and depersonalization
Describing, understanding, and explaining subjective experience in depression is a great challenge for psychopathology. Attempts to uncover neurobiological mechanisms of those experiences are in need

Depersonalization: neurobiological perspectives
Empathy and enduring depersonalization: The role of self-related processes
Findings suggest affective empathy to be reliant on intact emotional experience in the observer, and excessive self-focus may be detrimental to an empathic response.
Autonomic response in depersonalization disorder.
The fact that patients with depersonalization disorder respond earlier to a startling noise suggests that they are in a heightened state of alertness and that the reduced response to unpleasant stimuli is caused by a selective inhibitory mechanism on emotional processing.
Orientational Perception: II. Body Perception in Depersonalizationo
The phenomenon of depersonalization as the spontaneous complaint of a psychiatric patient of a distortion in perception of his body has received considerable clinical and speculative attention, but experimental information concerning it is very limited.
Feelings of Unreality: A Conceptual and Phenomenological Analysis of the Language of Depersonalization
The paper offers a conceptual and phenomenological analysis of the language of depersonalization. The depersonalization syndrome or disorder has no known common pathogenesis and shows no
Visual Imagery and Depersonalisation
It was found that symptoms of depersonalisation as well as other dissociative symptoms and depressed mood correlated with impaired ability to generate visual images, particularly evident with images pertaining to the self and other people as opposed to objects.
