The enigma of Bálint's syndrome: complexity of neural substrates and cognitive deficits by Magdalena Chechlacz,Glyn Humphreys Pdf

Bálint’s syndrome is named after the Hungarian physician who first reported a remarkable case of a man with complex visuospatial deficits following bilateral lesions within parietal and occipital cortex (Bálint, 1909). The syndrome has three primary symptoms: simultanagnosia (impaired spatial awareness of more than one object at time), optic ataxia (misreaching to visual targets) and ocular apraxia (described by Bálint as “psychic paralysis of gaze”). Balint’s patients not only cannot perceive more than one object at time and therefore show poor comprehension of multi-object visual scenes i.e. poor detection of all the objects present and difficulty in grasping the relationship between them; in addition they typically fail to reach towards location of the single object, which they can perceive. The deficit of the allocation of spatial attention in Balint’s syndrome has been linked to a problem in feature binding which results in illusory conjunctions. Patients with Balint’s syndrome also show deficits in global processing i.e. when integration of multiple local elements into global compound shapes is required. Consequently, Balint’s syndrome provides a unique opportunity to study the nature and neuroanatomy of human visuospatial processing, in particular multi-level object representation, spatial awareness and the distribution of visual attention. The studies collected here cover both the anatomical and the cognitive mechanisms of the different symptoms associated with the syndrome. Furthermore, the dissociations between the components of Bálints’ syndrome, in particular simultanagnosia and optic ataxia, can also co-occur with visual neglect and extinction and the different combinations of reported lesions raises a question about the status of the syndrome and whether it should be merely treated as a historical compilation of symptoms which may or may not coexist cohesively. This interesting argument is raised here.

The Metaphorical Brain by Seana Coulson,Vicky T. Lai Pdf

Metaphor has been an issue of intense research and debate for decades (see, for example [1]). Researchers in various disciplines, including linguistics, psychology, computer science, education, and philosophy have developed a variety of theories, and much progress has been made [2]. For one, metaphor is no longer considered a rhetorical flourish that is found mainly in literary texts. Rather, linguists have shown that metaphor is a pervasive phenomenon in everyday language, a major force in the development of new word meanings, and the source of at least some grammatical function words [3]. Indeed, one of the most influential theories of metaphor involves the suggestion that the commonality of metaphoric language results because cross-domain mappings are a major determinant in the organization of semantic memory, as cognitive and neural resources for dealing with concrete domains are recruited for the conceptualization of more abstract ones [4]. Researchers in cognitive neuroscience have explored whether particular kinds of brain damage are associated with metaphor production and comprehension deficits, and whether similar brain regions are recruited when healthy adults understand the literal and metaphorical meanings of the same words (see [5] for a review) . Whereas early research on this topic focused on the issue of the role of hemispheric asymmetry in the comprehension and production of metaphors [6], in recent years cognitive neuroscientists have argued that metaphor is not a monolithic category, and that metaphor processing varies as a function of numerous factors, including the novelty or conventionality of a particular metaphoric expression, its part of speech, and the extent of contextual support for the metaphoric meaning (see, e.g., [7], [8], [9]). Moreover, recent developments in cognitive neuroscience point to a sensorimotor basis for many concrete concepts, and raise the issue of whether these mechanisms are ever recruited to process more abstract domains [10]. This Frontiers Research Topic brings together contributions from researchers in cognitive neuroscience whose work involves the study of metaphor in language and thought in order to promote the development of the neuroscientific investigation of metaphor. Adopting an interdisciplinary perspective, it synthesizes current findings on the cognitive neuroscience of metaphor, provides a forum for voicing novel perspectives, and promotes avenues for new research on the metaphorical brain.

Principles of Behavioral and Cognitive Neurology by M.-Marsel Mesulam Pdf

This thoroughly revised new edition of a classic book provides a clinically inspired but scientifically guided approach to the biological foundations of human mental function in health and disease. It includes authoritative coverage of all the major areas related to behavioral neurology, neuropsychology, and neuropsychiatry. Each chapter, written by a world-renowned expert in the relevant area, provides an introductory background as well as an up-to-date review of the most recent developments. Clinical relevance is emphasized but is placed in the context of cognitive neuroscience, basic neuroscience, and functional imaging. Major cognitive domains such as frontal lobe function, attention and neglect, memory, language, prosody, complex visual processing, and object identification are reviewed in detail. A comprehensive chapter on behavioral neuroanatomy provides a background for brain-behavior interactions in the cerebral cortex, limbic system, basal ganglia, thalamus, and cerebullum. Chapters on temperolimbic epilepsy, major psychiatric syndromes, and dementia provide in-depth analyses of these neurobehavioral entities and their neurobiological coordinates. Changes for this second edition include the reflection throughout the book of the new and flourishing alliance of behavioral neurology, neuropsychology, and neuropsychiatry with cognitive science;major revision of all chapters; new authorship of those on language and memory; and the inclusion of entirely new chapters on psychiatric syndromes and the dementias. Both as a textbook and a reference work, the second edition of Principles of Behavioral and Cognitive Neurology represents an invaluable resource for behavioral neurologists, neuropsychologists, neuropsychiatrists, cognitive and basic neuroscientists, geriatricians, physiatrists, and their students and trainees.

Neuropsychological Neurology by A. J. Larner Pdf

Understanding the cognitive aspects of neurological disorders is essential to manage effectively patients suffering from these conditions. This book begins by outlining the various cognitive domains and how these can be tested, before covering in depth the cognitive deficits seen in prototypical neurodegenerative cognitive disorders (Alzheimer's disease, frontotemporal dementias, Huntington's disease, prionoses) and other common neurological disorders that may be complicated by cognitive impairment (stroke, multiple sclerosis, Parkinson's disease, brain tumours). This second edition has been completely revised and updated, with new material added throughout, including two new chapters: 'Sleep-Related Disorders' and 'Psychiatric Disorders in the Cognitive Function Clinic'. This an essential reference for all neurologists, not just for those with an interest in cognitive disorders. General physicians and specialists who deal with endocrine, metabolic, vascular or infective disorders that may compromise cognitive function, and allied health professionals who work with cognitively impaired patients, will also find this text useful.

Brain Mechanisms and Spatial Vision by D.J. Ingle,Marc Jeannerod,David Lee Pdf

This volume contains chapters derived from a N. A. T. O. Advanced Study Institute held in June 1983. As the director of this A. S. I. it was my hope that some of the e1ectrophysiologists could express the potentialities of their work for perceptual theory, and that some perceptionists could speculate on the underlying "units" of perception in a way that would engage the imagination of physio logists. The reader will have to be the judge of whether this was achieved, or whether such a psychophysiological inter1ingua is still overly idealistic. It is clear that after the revolution prec~pitated by Hube1 and Weisel in understanding of visual cortical neurons we still have only a foggy idea of the behavioral output of any particular species of cortical detector. It was therefore particularly unfortunate that two persons who have made great strides in correlating interesting facets of cat cortical physio logy with human psychophysics (Max Cynader and Martin Regan of Dalhousie University) were unable to attend this meeting. Never theless, a number of new and challenging ideas regarding both spatial perception and cortical mechanisms are represented in this volume, and it is hoped that the reader will remember not only the individual demonstrations but the critical questions posed by the apposition of the two different collections of experimental facts.
