Neuroimaging, Software, and Communication


Book Description

This book analyses the social contexts in which programmers design neuroimaging software used in brain studies. It shows that in the same way people engage in everyday communication, programmers are involved in a series of communicative processes to realize the negotiations and discussions generated by software development. In this way, highly technical activities such as computer code writing are also underpinned by values, preferences, and power relations. At the same time, the book sheds new light on scientists’ increasing dependence on software. On the one hand, many scientific tasks can no longer be performed without the help of computational technologies. On the other hand, most scientists have only superficial computing knowledge. As a result, inequalities emerge whereby some scientists take the most strategic methodological decisions whereas other scientists can only rely on the technical help provided by user-friendly computer applications.




Neuroimaging in Communication Sciences and Disorders


Book Description

The rate of development in neuroimaging is so rapid that it is almost impossible to predict very far into the future in trying to understand this influence. The availability of technologies that make it possible to investigate, even in real time, the neural regions and systems that are functionally related disorders is having a transforming impact on the discipline. This book presents findings by some of the principal researchers in the field and who are working at the cutting-edge in applying neuroimaging to communication disorders.




Neurotechnology and Direct Brain Communication


Book Description

Neurotechnology and Direct Brain Communication focuses on recent neuroscientific investigations of infant brains and of patients with disorders of consciousness (DOC), both of which are at the forefront of contemporary neuroscience. The prospective use of neurotechnology to access mental states in these subjects, including neuroimaging, brain simulation, and brain computer interfaces, offers new opportunities for clinicians and researchers, but has also received specific attention from philosophical, scientific, ethical, and legal points of view. This book offers the first systematic assessment of these issues, investigating the tools neurotechnology offers to care for verbally non-communicative subjects and suggesting a multidisciplinary approach to the ethical and legal implications of ordinary and experimental practices. The book is divided into three parts: the first and second focus on the scientific and clinical implications of neurological tools for DOC patient and infant care. With reference to these developments, the third and final part presents the case for re-evaluating classical ethical and legal concepts, such as authority, informed consent, and privacy. Neurotechnology and Direct Brain Communication will appeal to researchers and postgraduate students in the fields of cognitive science, medical ethics, medical technology, and the philosophy of the mind. With implications for patient care, it will also be a useful resource for clinicians, medical centres, and health practitioners.




Handling Digital Brains


Book Description

"FMRI tesearchers do not sit passively staring at computer screens but actively involve their bodies in laboratory practice. Discussing fMRI visuals with colleagues, scientists animate the scans with gestures and talk as they work with computers. Alač argues that to understand how digital scientific visuals take on meaning, we must consider their dynamic coordination with gestures, speech, and working hands. These multimodal interactions, she suggests, are an essential component of digital scientific works ... Scientific practices in the fMRI lab demonstrate thinking that engages the whole lived body and the world in which the body is situated. The turn toward the digital does not bring with it abstraction but a manual and embodied engagement. The practical and multimodal engagement with digital brains in the laboratory challenges certain assumptions behind fMRI technology; it suggests our hands are essential to learning and the making of meaning."--Jacket description.




Between Theory and Clinic: The Contribution of Neuroimaging in the Field of Consciousness Disorders


Book Description

The amount of patients surviving severe brain injury has gradually increased over these last decades thanks to the development of intensive care. These patients either recover quickly from coma or go through prolonged disorders of consciousness such as vegetative state/unresponsive wakefulness syndrome (VS/UWS) or minimally conscious state (MCS). While patients in a minimally conscious state are to some extent aware of themselves and the environment, and show fluctuating but reproducible signs of consciousness, patients in a vegetative state/unresponsive wakefulness syndrome are awake but only show reflexive behaviors. These patients are unable to communicate and present vigilance fluctuation, sensory deficits as well as severe motor and language impairments. Even though behavioral assessment currently remains the gold standard for diagnosis, a number of studies highlights the difficulty in making the distinction between conscious and unconscious patients based on clinical examinations and show a misdiagnosis rate as high as 40%. Misdiagnosis can nevertheless have serious consequences on patient’s management, medically but also ethically (i.e., regarding end-of-life decision). The emergence of functional neuroimaging techniques (such as positron emission tomography – PET and functional magnetic resonance imaging – fMRI) opened new opportunities to study brain activity in patients with disorders of consciousness (DOC). Recent neuroimaging tools have brought new understandings on how the brain functions after coma, and how these tools can complement bedside assessment by improving diagnosis and prognosis of DOC patients. Indeed, we know now that most patients in VS/UWS present partial activation of sensory networks and impaired functional connectivity contrary to patients in MCS. The reemergence of thalamo-cortical connections has also been associated with recovery of consciousness; whereas, thalamic atrophy has been associated to chronic DOC. Recent findings have also stressed the interest of neuroimaging in the management and the treatment of these patients. fMRI has been used as brain computer interfaces to detect consciousness in unresponsive patients and to allow basic communication in minimally conscious patients. Neuroimaging techniques are also currently being used to examine the effects of potential therapy such as pharmacological medications (e.g., Amantadine or Zolpidem) and brain stimulations (e.g., transcranial direct current stimulation or repetitive transcranial magnetic stimulation).




Collaborative Efforts for Understanding the Human Brain


Book Description

Neuroimaging in Neurogenic Communication Disorders


Book Description

Neuroimaging in Neurogenic Communication Disorders provides a comprehensive review of cases utilizing neuroimaging in neurogenic communication disorders. Basic knowledge of neuroanatomy and medical conditions related to these speech and language disorders are discussed. Each case study includes information on neuroanatomy, case presentation, neuroimaging, differential diagnosis, and final diagnosis. This book is written for medical students, practitioners and researchers in neuroscience and speech language pathology. Neurogenic communication disorders are caused by damage to the central or peripheral nervous system. This damage can be caused by Parkinson's disease, stroke, dementia, traumatic brain injury, brain tumors, and other neurologic disorders and causes issues such as aphasia, dysarthria and apraxia.
