Pure Word Deafness , or auditory verbal agnosia, is caused by bilateral damage to the posterior superior temporal lobe s or disruption of connections between these areas. It exhibits itself as inability to comprehend the meaning of speech, but in most cases still being able to hear, speak, read, and write. Individuals that exhibit pure word deafness are usually also able to comprehend non verbal sounds. ref name Wolberg cite journal author Wolberg SC, Temlett JA, Fritz VU title Pure word deafness journal S.

Hermann Wilbrand May 22, 1851 &ndash 1935 was a German ophthalmologist born in Giessen . Wilbrand s father and grandfather were also physicians. In 1875 he earned his doctorate at the University of Strassburg , and afterwards was an assistant to Ludwig Laqueur 1839 1909 at Strassburg and to Carl Friedrich Richard F rster 1825 1902 at Breslau . Later he moved to Hamburg , where he became head of the Department of Ophthalmology at Allgemeines Hospital in 1905. Wilbrand specialized in the field of neuro ophthalmology and did extensive research involving the pathology and physiology of the eye. He demonstrated that homonymous hemianopsia was caused by lesions in the occipital lobe and optic radiation as well as the optic tract . Associated eponyms Wilbrand s knee A group of macula extramacular ganglion cell axon s that extend forward into the posterior optic nerve .

He was a neurologist at the psychiatric hospital in Breslau , and was a one time assistant to Carl Wernicke . Lissauer is known for his description of the posterolateral tract of the spinal cord which was to become known as Lissauer s tract . Another eponymous term associated with Lissauer is Lissauer s paralysis , which is an apoplexy apoplectic type of general paresis . He also published an influential treatise on visual agnosia , which was called Seelenblindheit in 19th century German medicine, and it roughly translates to soul blindness . Lissauer died in Hallstatt , Austria on September 21, 1891 at the age of 30.

Martha Farah is a cognitive neuroscience researcher at the University of Pennsylvania . She has worked on an unusually wide range of topics the citation for her lifetime achievement award from the Association for Psychological Science states that Her studies on the topics of mental imagery, face recognition, semantic memory, reading, attention, and executive functioning have become classics in the field. Farah has undergraduate degrees in Metallurgy and Philosophy from MIT, and a doctorate in Psychology from Harvard University. She has taught at Carnegie Mellon University and at the University of Pennsylvania, where she is now Walter H. Annenberg Professor of Natural Sciences and Director of the Center for Neuroscience & Society. Early work Farah s early work focused on the neural bases of vision and memory. In her 1990 book, Visual Agnosia Disorders of Object Recognition and What They Tell Us about Normal Vision MIT Press , she framed many of the questions about visual recognition that the next two decades of cognitive neuroscience research addressed. These questions include whether the human brain uses a general purpose pattern recognition system for all classes of visual object or whether there is specialization for face recognition and or printed word recognition, and whether semantic memory knowledge is organized in the brain by category e.g., living vs nonliving things or modality e.g. visual vs motoric information . Her research revealed a striking degree of division of labor, with specialized systems for a various categories of stimuli and types of information, and was summarized in The Cognitive Neuroscience of Vision Wiley Blackwell, 2000 and in the second edition of Visual Agnosia MIT Press, 2004 . Farah was also among the first information processing psychologists to use the behavior of neurological patients to test cognitive theories, starting in the early 1980s.

Memory can be defined as an organism s ability to encoding memory encode , retain, and recall memory recall information. Disorders of memory can range from mild to severe, yet are all a result of damage to neuroanatomical structures either in part or in full. This damage hinders the storage, retention and recollection of memories. Memory disorders can be progressive, including Alzheimer s disease , or they can be immediate including disorders resulting from head injury . Memory disorders in alphabetical order Agnosia Agnosia is the inability to recognize certain objects, persons or sounds, yet there are many more specific diagnoses of agnosia. Agnosia is typically caused by damage to the brain most commonly in the occipital or parietal lobes or from a neurological disorder. Treatments vary depending on the location and cause of the damage.

Zasetsky suffered a severe Acquired brain injury brain injury , losing his ability to read, write, and speak retrieving desired words was particularly difficult , and suffering impaired vision, memory, and other functions. He was notable for the tenacity and to some extent, success with which he fought to regain a normal life, and for what the pattern of his deficits helped cognitive scientists to learn about brain function . He also wrote a journal of his experience, which itself was extraordinarily difficult for him. He was 23 years old when injured in the Battle of Smolensk 1943 Battle of Smolensk on March 2, 1943. A bullet entered his left Parietal lobe parieto Occipital lobe occipital area, and resulted in a long coma . Following this he developed a form of agnosia and became unable to perceive the right side of things. Objects he did see often appeared as fragmented pieces rather than whole objects. Even the right side of his own body was invisible to him, an experience that remained terrifying even years later. Luria, who treated Zasetsky over the course of 26 years, published Zasetsky s journal and a detailed case history in The Man with a Shattered World The History of a Brain Wound . ref The Man with a Shattered World The History of a Brain Wound , translated by Lynn Solotaroff, Cambridge, Harvard University Press, 2004, ISBN 0674546253 ref In 2002 Robert Wood wrote a radio play about Zasetsky based on Luria s book. ref http luria.ucsd.edu I ll 20fight 20on.htm I LL FIGHT ON, A radio play for two voices, by Robert Wood, Adapted with the permission of Harvard University Press from the book The Man with a Shattered World by A.R.Luria, May 2002 ref References reflist See also Solomon Shereshevskii Persondata Metadata see Wikipedia Persondata .

Localizationist neurology and clinical descriptions reached a peak in the late 19th and early 20th century, with work extending into the clinical descriptions of dementias by Alois Alzheimer and Arnold Pick . The work of Karl Lashley in rats for a time in the early to mid 20th century put a damper on localization theory and lesion models of behavioral function.

There is significant debate in the scientific literature as to whether Gerstmann Syndrome truly represents a unified, theoretically motivated syndrome.

Test Most individuals about 95 of the time ref name james who are right handed are left cortical hemisphere dominant, while about 10 of individuals who are left handed, are right cortical hemisphere dominant. The dominance refers to the Cerebral cortex cortex where often propositional language centers such as Broca s area located in pars opercularis and pars triangularis of the frontal lobe responsible for generation of speech, Wernicke s area located in superior temporal gyrus , responsible for comprehension of speech, and other motor and somatosensory areas are located. The dominant hemisphere is therefore responsible for language, and comprehension of speech.
