  • Bodily Awareness, Pain, and the Self by Adam L Bradley a Dissertation
    Sensitive Subjects: Bodily Awareness, Pain, and the Self by Adam L Bradley A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Philosophy in the Graduate Division of the University of California, Berkeley Committee in charge: Professor John Campbell, Co-chair Professor Geoffrey Lee, Co-chair Professor Michael Martin Professor Alison Gopnik Summer 2019 Abstract Sensitive Subjects: Bodily Awareness, Pain, and the Self by Adam L Bradley Doctor of Philosophy in Philosophy University of California, Berkeley Professor John Campbell, Co-chair Professor Geoffrey Lee, Co-chair Imagine that you feel a pain in your hand, notice the movement of your limbs as you tie your shoes, or attend to your feeling of balance as you ride a rollercoaster. These phenomena are exercises of bodily awareness, the type of awareness one has of one’s body ‘from the inside.’ My dissertation is an investigation into the nature of bodily awareness. In it I describe and attempt to resolve a number of serious puzzles raised by the philosophical and scientific investigation of bodily self-awareness. My solution to these puzzles is to develop a novel account of bodily awareness. On the view I develop bodily awareness is basic, irreducible to other mental capacities such as perception and introspection. Only by treating bodily awareness as basic, I argue, can we understand what is distinctive about it. I begin by establishing the unity of bodily awareness. Though bodily awareness is comprised of sensory systems that are physically, functionally, and phenomenologically distinct, these distinct sensory systems nevertheless generate a single form of awareness.

  • Three-Dimensional Coherence of the Conscious Body'image
    THE QUARTERLY JOURNAL OF EXPERIMENTAL PSYCHOLOGY, 2015 Vol. 68, No. 6, 1116–1123, http://dx.doi.org/10.1080/17470218.2014.975731 Three-dimensional coherence of the conscious body image Matthew R. Longo Department of Psychological Sciences, Birkbeck, University of London, London, UK (Received 19 February 2014; accepted 10 July 2014; first published online 18 November 2014) We experience our body as a coherent object in the three-dimensional (3-D) world. In contrast, the body is represented in somatosensory cortex as a fragmented collection of two-dimensional (2-D) maps. Recent results have suggested that some forms of higher level body representations maintain this fragmentation, for example by showing different patterns of distortion for two surfaces of a single body part, such as the palmar and dorsal hand surfaces. This study investigated the 3-D coher- ence of the conscious body image of the hand by comparing perceptual biases of perceived hand shape on the dorsal and palmar surfaces. Participants made forced-choice judgements of whether observed hand images were thinner or wider than their own left or right hand, and perceptual distortions of the hand image were assessed by fitting psychometric functions. The results suggested that the hand is consciously represented as a fully coherent, 3-D object. Specifically: (a) Similar overall levels of dis- tortion were found on the palmar and dorsal hand surfaces, (b) comparable laterality effects were found on both surfaces (left hand represented as wider than right hand), and (c) the magnitude of distortions were strongly correlated across the two surfaces. Whereas other recent results have suggested that per- ceptual abilities such as position sense, tactile size perception, and tactile localization may rely on frag- mented, 2-D representations of individual skin surfaces, the present results suggest that, in striking contrast, the conscious body image represents the body (or, at least the hand) as a coherent, 3-D object.

These disorders are not merely historical curiosities, however. As apraxia, neglect, and agnosia have important clinical implications, it is important to possess a working knowledge of the conditions and how to identify them. RECENT FINDINGS: Apraxia is a disorder of skilled action that is frequently observed in the setting of dominant hemisphere pathology, whether from stroke or neurodegenerative disorders. In contrast to some previous teaching, apraxia has clear clinical relevance as it is associated with poor recovery from stroke. Neglect is a complex disorder with CITE AS: many different manifestations that may have different underlying CONTINUUM (MINNEAP MINN) mechanisms. Neglect is, in the author’s view, a multicomponent disorder 2018;24(3,

  • Phantoms in the Brain.Pdf
    PHANTOMS IN THE BRAIN Probing the Mysteries of the Human Mind V.S. Ramachandran, M.D., Ph.D., and Sandra Blakeslee Copyright © 1998 ISBN 0688152473 To my mother, Meenakshi To my father, Subramanian To my brother, Ravi To Diane, Mani and Jayakrishna To all my former teachers in India and England 1 To Saraswathy, the goddess of learning, music and wisdom Foreword The great neurologists and psychiatrists of the nineteenth and early twentieth centuries were masters of description, and some of their case histories provided an almost novelistic richness of detail. Silas Weir Mitchell—who was a novelist as well as a neurologist—provided unforgettable descriptions of the phantom limbs (or "sensory ghosts," as he first called them) in soldiers who had been injured on the battlefields of the Civil War. Joseph Babinski, the great French neurologist, described an even more extraordinary syndrome—anosognosia, the inability to perceive that one side of one's own body is paralyzed and the often−bizarre attribution of the paralyzed side to another person. (Such a patient might say of his or her own left side, "It's my brother's" or "It's yours.") Dr. V.S. Ramachandran, one of the most interesting neuroscientists of our time, has done seminal work on the nature and treatment of phantom limbs—those obdurate and sometimes tormenting ghosts of arms and legs lost years or decades before but not forgotten by the brain. A phantom may at first feel like a normal limb, a part of the normal body image; but, cut off from normal sensation or action, it may assume a pathological character, becoming intrusive, "paralyzed," deformed, or excruciatingly painful—phantom fingers may dig into a phantom palm with an unspeakable, unstoppable intensity.

  • Can Vestibular Caloric Stimulation Be Used to Treat Apotemnophilia? Q
    Medical Hypotheses (2007) 69, 250–252 http://intl.elsevierhealth.com/journals/mehy Can vestibular caloric stimulation be used to treat apotemnophilia? q V.S. Ramachandran, Paul McGeoch * Center for brain and cognition, UCSD, La Jolla, CA 9209, United States Received 30 November 2006; accepted 3 December 2006 Summary Apotemnophilia, or body integrity image disorder (BIID), is characterised by a feeling of mismatch between the internal feeling of how one’s body should be and the physical reality of how it actually is. Patients with this condition have an often overwhelming desire for an amputation- of a specific limb at a specific level. Such patients are not psychotic or delusional, however, they do express an inexplicable emotional abhorrence to the limb they wish removed. It is also known that such patients show a left-sided preponderance for their desired amputation. Often they take drastic action to be rid of the offending limb. Given the left-sided bias, emotional rejection and specificity of desired amputation, we suggest that there are clear similarities to be drawn between BIID and somatoparaphrenia. In this rare condition, which follows a right parietal stroke, the patient rejects (usually) his left arm as ‘‘alien’’. We go on to hypothesis that a dysfunction of the right parietal lobe is also the cause of BIID. We suggest that this leads to an uncoupling of the construct of one’s body image in the right parietal lobe from how one’s body physically is. This hypothesis would be amenable to testing by response to cold-water vestibular caloric stimulation, which is known to temporarily treat somatoparaphrenia.

Fischer (Eds.), Foundations of Embodied Cognition, Volume 1: Perceptual and Emotional Embodiment (pp. 117-134). London: Routledge. Types of Body Representation Matthew R. Longo Department of Psychological Sciences, Birkbeck, University of London Malet Street, London WC1E 7HX, United Kingdom 1 Abstract Our body is an essential component of our sense of self and the core of our identity as an individual. Disorders of body representation, moreover, are a central aspect of several serious clinical conditions. A large and growing literature has therefore investigated the cognitive and neural mechanisms by which we represent our bodies and how these may become disrupted in disease. In this chapter I will give a brief overview of six types of body representation: (1) the body image, a conscious image of the size, shape, and physical composition of our bodies; (2) the body schema, a dynamic model of the body posture underlying skilled action; (3) the superficial schema, mediating localisation of stimuli on the body surface; (4) the body model, a model of the metric properties of the body underlying perception; (5) the body as a distinct semantic domain; and (6) the body structural description, a topological model of the locations of body parts relative to each other. 2 Our body is an essential component of our sense of self and the core of our identity as an individual. Distortions and misperceptions of the body are a central part of serious psychiatric conditions

  • Some Unusual Neuropsychological Syndromes: Somatoparaphrenia
    Archives of Clinical Neuropsychology Advance Access published May 4, 2016 Some Unusual Neuropsychological Syndromes: Somatoparaphrenia, Akinetopsia, Reduplicative Paramnesia, Autotopagnosia Alfredo Ardila* Department of Communication Sciences and Disorders, Florida International University, Miami, FL, USA *Corresponding authorat: Department of Communication Sciences and Disorders, Florida International University, Miami,11200 SW 8th Street, AHC3-431B, FL 33199, USA. Tel.: +1-305-348-2750; fax: +1-305-348-2710. E-mail address: ardilaa@fiu.edu (A. Ardila). Accepted 25 March 2016 Downloaded from Abstract Some unusual neuropsychological syndromes are rarely reported in the neuropsychological literature. This paper presents a review of four of these unusual clinical syndromes: (1) somatoparaphrenia (delusional belief in which a patient states that the limb contralateral to a brain path- http://acn.oxfordjournals.org/ ology, does not belong to him/her); (2) akinetopsia (cortical syndrome in which patient losses the ability to perceive visual motion); (3) redupli- cative paramnesia (believe that a familiar place, person, object, or body part has been duplicated); and (4) autotopagnosia (disturbance of body schema involving the loss of ability to localize, recognize, or identify the specific parts of one’s body). It is concluded that regardless of their rarity, it is fundamental to take them into consideration in order to understand how the brain organizes cognition; their understanding is also crucial in the clinical analysis of patients with brain pathologies. Keywords: Somatoparaphrenia; Akinetopsia; Reduplicative paramnesia; Autotopagnosia by guest on May 4, 2016 There are some unusual neuropsychological syndromes rarely reported in the neuropsychological literature. Somatoparaphrenia, akinetopsia, reduplicative paramnesias, and autotopagnosia are just four examples of these unusual clinical syndromes.
