Lev Zasetsky
Lev Alexandrovich Zasetsky (9 August 1920 – 9 September 1993) was a patient who was treated by Soviet neuropsychologist Alexander Luria. Zasetsky suffered a severe 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 on March 2, 1943. A bullet entered his left parieto- occipital area, and resulted in a long coma. Following this he developed a form of agnosia Agnosia is a neurological disorder characterized by an inability to process sensory information. Often there is a loss of ability to re ...

Neuropsychologist
Neuropsychology is a branch of psychology concerned with how a person's cognition and behavior are related to the brain and the rest of the nervous system. Professionals in this branch of psychology focus on how injuries or illnesses of the brain affect cognitive and behavioral functions. It is both an experimental and clinical field of patient-focused psychology. Thus aiming to understand how behavior and cognition are influenced by brain function. It is also concerned with the medical diagnosis, diagnosis and therapy, treatment of behavioral and cognitive effects of neurological disorders. Whereas classical neurology focuses on the pathology of the nervous system and classical psychology is largely divorced from it, neuropsychology seeks to discover how the brain neural correlates of consciousness, correlates with the mind through the study of neurological patients. It thus shares concepts and concerns with neuropsychiatry and with behavioral neurology in general. The term ''ne ...

Alexander Luria
Alexander Romanovich Luria (; , ; 16 July 1902 – 14 August 1977) was a Soviet neuropsychology, neuropsychologist, often credited as a father of modern neuropsychology. He developed an extensive and original battery of neuropsychological assessment, neuropsychological tests during his clinical work with brain-injured victims of World War II, which are still used in various forms. He made an in-depth analysis of the functioning of various brain regions and integrative processes of the brain in general. Luria's magnum opus, ''Higher Cortical Functions in Man'' (1962), is a much-used psychological textbook which has been translated into many languages and which he supplemented with ''The Working Brain'' in 1973. It is less known that Luria's main interests, before the war, were in the field of cultural and developmental research in psychology. He became famous for his studies of low-educated populations of nomadic Uzbeks in the Uzbek Soviet Socialist Republic, Uzbek SSR argui ...

Acquired Brain Injury
Acquired brain injury (ABI) is brain damage caused by events after birth, rather than as part of a genetic or congenital disorder such as fetal alcohol syndrome, perinatal illness or perinatal hypoxia. ABI can result in cognitive, physical, emotional, or behavioural impairments that lead to permanent or temporary changes in functioning. These impairments result from either traumatic brain injury (e.g. physical trauma due to accidents, assaults, neurosurgery, head injury etc.) or nontraumatic injury derived from either an internal or external source (e.g. stroke, brain tumours, infection, poisoning, hypoxia, ischemia, encephalopathy or substance abuse). ABI does not include damage to the brain resulting from neurodegenerative disorders. While research has demonstrated that thinking and behavior may be altered in virtually all forms of ABI, brain injury is itself a very complex phenomenon having dramatically varied effects. No two persons can expect the same outcome or result ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cognitive
Cognition is the "mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses all aspects of intellectual functions and processes such as: perception, attention, thought, imagination, intelligence, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and computation, problem-solving and decision-making, comprehension and production of language. Cognitive processes use existing knowledge to discover new knowledge. Cognitive processes are analyzed from very different perspectives within different contexts, notably in the fields of linguistics, musicology, anesthesia, neuroscience, psychiatry, psychology, education, philosophy, anthropology, biology, systemics, logic, and computer science. These and other approaches to the analysis of cognition (such as embodied cognition) are synthesized in the developing field of cognitive science, a progressively auton ...

Brain Function
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing, and olfaction. Being the most specialized organ, it is responsible for receiving information from the sensory nervous system, processing that information (thought, cognition, and intelligence) and the coordination of motor control (muscle activity and endocrine system). While invertebrate brains arise from paired segmental ganglia (each of which is only responsible for the respective body segment) of the ventral nerve cord, vertebrate brains develop axially from the midline dorsal nerve cord as a vesicular enlargement at the rostral end of the neural tube, with centralized control over all body segments. All vertebrate brains can be embryonically divided into three parts: the forebrain (prosencephalon, subdivided ...

Battle Of Smolensk (1943)
The second Smolensk operation (code naming "Alexander Suvorov, Suvorov";Istomin (1975), pp. 20–21 7 August – 2 October 1943) was a Soviet strategic offensive operation conducted by the Red Army as part of the Summer-Autumn Campaign of 1943. Staged almost simultaneously with the Lower Dnieper Offensive (13 August – 22 September), the offensive lasted two months and was led by General Andrei Yeremenko, commanding the Kalinin Front, and Vasily Sokolovsky, commanding the Western Front (Soviet Union), Western Front. Its goal was to clear the German presence from the Smolensk and Bryansk regions. Smolensk had been under German occupation since the first Battle of Smolensk (1941), Battle of Smolensk in 1941. Despite an impressive German defense, the Red Army was able to stage several breakthroughs, liberating several major cities, including Smolensk and Roslavl. As a result of this operation, the Red Army was able to start planning for the liberation of Belarus. However, the overa ...

Parietal Lobe
The parietal lobe is one of the four Lobes of the brain, major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus. The parietal lobe integrates sensory information among various sensory modality, modalities, including spatial sense and navigation (proprioception), the main sensory receptive area for the sense of touch in the somatosensory cortex which is just posterior to the central sulcus in the postcentral gyrus, and the two-streams hypothesis#Dorsal stream, dorsal stream of the visual system. The major sensory inputs from the skin (mechanoreceptor, touch, thermoreceptor, temperature, and nociceptor, pain receptors), relay through the thalamus to the parietal lobe. Several areas of the parietal lobe are important in language processing in the brain, language processing. The somatosensory cortex can be illustrated as a distorted figure – the cortical homunculus (Latin: "li ...

Occipital Lobe
The occipital lobe is one of the four Lobes of the brain, major lobes of the cerebral cortex in the brain of mammals. The name derives from its position at the back of the head, from the Latin , 'behind', and , 'head'. The occipital lobe is the Visual perception, visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. The primary visual cortex is Brodmann area, Brodmann area 17, commonly called V1 (visual one). Human V1 is located on the Anatomical terms of location#Left and right (lateral), and medial, medial side of the occipital lobe within the calcarine sulcus; the full extent of V1 often continues onto the cerebral hemisphere#Poles, occipital pole. V1 is often also called striate cortex because it can be identified by a large stripe of myelin, the stria of Gennari. Visually driven regions outside V1 are called Extrastriate, extrastriate cortex. There are many extrastriate regions, and these are specialized for different ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Coma
A coma is a deep state of prolonged unconsciousness in which a person cannot be awakened, fails to Nociception, respond normally to Pain, painful stimuli, light, or sound, lacks a normal Circadian rhythm, sleep-wake cycle and does not initiate voluntary actions. The person may experience respiratory and circulatory problems due to the body's inability to maintain normal bodily functions. People in a coma often require extensive medical care to maintain their health and prevent complications such as pneumonia or blood clots. Coma patients exhibit a complete absence of wakefulness and are unable to consciously feel, speak or move. Comas can be the result of natural causes, or can be Induced coma, medically induced, for example, during General anaesthesia, general anesthesia. Clinically, a coma can be defined as the consistent inability to follow a one-step command. For a patient to maintain consciousness, the components of ''wakefulness'' and ''awareness'' must be maintained. Wak ...

Agnosia
Agnosia is a neurological disorder characterized by an inability to process sensory information. Often there is a loss of ability to recognize objects, persons, sounds, shapes, or smells while the specific sense is neither defective nor is there any significant memory loss. It is usually associated with brain injury or neurological illness, particularly after damage to the occipitotemporal border, which is part of the ventral stream. Agnosia affects only a single modality, such as vision or hearing. More recently, a top-down interruption is considered to cause the disturbance of handling perceptual information. Types Visual agnosia Visual agnosia is a broad category that refers to a deficiency in the ability to recognize visual objects. Visual agnosia can be further subdivided into two different subtypes: apperceptive visual agnosia and associative visual agnosia. Individuals with apperceptive visual agnosia display the ability to see contours and outlines w ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Solomon Shereshevskii
Solomon Veniaminovich Shereshevsky (; 1886 – 1 May 1958), also known simply as 'Ш' ('Sh'), 'S.', or Luria's S, was a Soviet journalist and mnemonist active in the 1920s. He was the subject of Alexander Luria's case study ''The Mind of a Mnemonist'' (1968). Studies Shereshevsky participated in many psychological studies, most of them carried out by the neuropsychologist Alexander Luria over a thirty-year time span. He met Luria after an anecdotal event in which he was scolded for not taking any notes while attending a work meeting in the mid-1920s. To the astonishment of everyone there (and to his own astonishment in realizing that others could apparently not do so), he could recall the speech word for word. Throughout his life, Shereshevsky was tasked with memorizing complex mathematical formulas, huge matrices, and even poems in foreign languages that he had never spoken before, all of which he would memorize with meticulous accuracy in a matter of minutes. On the basis of h ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Phineas Gage
Phineas P. Gage (18231860) was an American railroad construction foreman remembered for his improbable survival of an accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining 12 years of his lifeeffects sufficiently profound that friends saw him (for a time at least) as "no longer Gage". Long known as the "American Crowbar Case"once termed "the case which more than all others is to excite our wonder, impair the value of prognosis, and even to subvert our doctrines"Phineas Gage influenced 19th-century discussion about the mind and brain, debate on cerebral , and was perhaps the first case to suggest the brain's role in , and that damage to specific parts of the brain might induce specific mental changes. Gage is a fixture in the curricula of neurology, psychology, and neuroscience, one of "the great medical curiosit ...
