V. S. Ramachandran
Vilayanur Subramanian Ramachandran (born 10 August 1951) is an Indian-American neuroscientist. He is known for his wide-ranging experiments and theories in behavioral neurology, including the invention of the mirror box. Ramachandran is a distinguished professor in UCSD's Department of Psychology, where he is the director of the Center for Brain and Cognition. After earning a medical degree in India, Ramachandran studied experimental neuroscience at Cambridge, obtaining his PhD there in 1978. Most of his research has been in the fields of behavioral neurology and visual psychophysics. After early work on human vision, Ramachandran turned to work on wider aspects of neurology including phantom limbs and phantom pain. Ramachandran also performed the world's first "phantom limb amputation" surgeries by inventing the mirror therapy, which is now widely used for reducing phantom pains (and eliminating phantom sensations altogether in long term), and also for helping to restore motor ...

Time 100
''Time'' 100 is a list of the top 100 most influential people, assembled by the American news magazine ''Time''. First published in 1999 as the result of a debate among American academics, politicians, and journalists, the list is now a highly publicized annual event. It is generally considered an honor to be included on the list, but ''Time'' makes it clear that entrants are recognized for changing the world, regardless of the consequences of their actions. The final list of influential individuals is exclusively chosen by ''Time'' editors, with nominations coming from the ''Time'' 100 alumni and the magazine's international writing staff. Only the winner of the Reader's Poll, conducted days before the official list is revealed, is chosen by the general public. The corresponding commemorative gala is held annually in Manhattan, and has emerged as one of the world's most celebrated galas as well as high fashion events. In 2019, ''Time'' began publishing the ''Time'' 100 Next l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Capgras Syndrome
Capgras delusion or Capgras syndrome is a psychiatric disorder in which a person holds a delusion that a friend, spouse, parent, other close family member, or pet has been replaced by an identical impostor. It is named after Joseph Capgras (1873–1950), the French psychiatrist who first described the disorder. The Capgras delusion is classified as a delusional misidentification syndrome, a class of beliefs that involves the misidentification of people, places, or objects. It can occur in acute, transient, or chronic forms. Cases in which patients hold the belief that time has been "warped" or "substituted" have also been reported. The delusion most commonly occurs in individuals diagnosed with a psychotic disorder, usually schizophrenia; it has also been seen in brain injury, dementia with Lewy bodies, and other forms of dementia. It presents often in individuals with a neurodegenerative disease, particularly at an older age; it has also been reported as occurring in assoc ...

The Tell-Tale Brain
''The Tell-Tale Brain: A Neuroscientist's Quest for What Makes Us Human'' is a 2010 nonfiction book by V. S. Ramachandran that explores the uniqueness of human nature from a neurological viewpoint. Synopsis Ramachandran discusses seven main concepts which define the human aspect of self and how each may be disrupted by a specific neurological disorder. The concepts are: unity, continuity, embodiment, privacy, social embedding, free will, and self-awareness. In the first chapter, Ramachandran discusses the human ability to change and adapt, illustrating the concept from his work on phantom limbs. The second chapter describes some of his work with visual perception and cognition, addressing the concept of human awareness. In chapter three, he connects ideas about synesthesia to creativity. Chapters four and five talk about mirror neurons, while chapter six discusses human language. Ramachandran proposes "nine laws of aesthetics," which he discusses in chapters seven and eight. ...

Phantoms In The Brain
''Phantoms in the Brain: Probing the Mysteries of the Human Mind'' (also published as ''Phantoms in the Brain: Human Nature and the Architecture of the Mind'') is a 1998 popular science book by neuroscientist V.S. Ramachandran and ''New York Times'' science writer Sandra Blakeslee, discussing neurophysiology and neuropsychology as revealed by case studies of neurological disorders. The book, which began as a lecture presented to the Society for Neuroscience, features a foreword by neuroscientist and author Oliver Sacks. Synopsis Ramachandran discusses his work with patients exhibiting phantom limbs, the Capgras delusion, pseudobulbar affect and hemispatial neglect following stroke, and religious experiences associated with epileptic seizure, among other disorders. Ramachandran uses these cases to illustrate the construction of body image, and the functioning of mood, decision-making, self-deception, and artistic skill. In the final chapter of the book, Ramachandran addresses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phantom Pain
Phantom pain is a Pain, painful perception that an individual experiences relating to a Limb (anatomy), limb or an Organ (biology), organ that is not physically part of the body, either because it was amputation, removed or was never there in the first place. Sensations are reported most frequently following the amputation of a limb, but may also occur following the removal of a breast, tongue, or internal organ. Phantom eye syndrome can occur after eye loss. The pain sensation and its duration and frequency varies from individual to individual. Phantom pain should be distinguished from other conditions that may present similarly, such as phantom limb sensation and residual limb pain. Phantom limb sensation is any sensory phenomenon, except pain, which is felt at an absent limb or a portion of the limb. It is estimated that up to 80% of amputees experience phantom limb sensations at some time of their lives. Some experience some level of this phantom feeling in the missing limb f ...

Phantom Limbs
A phantom limb is the sensation that an amputated or missing limb is still attached. It is a chronic condition that is often resistant to treatment. When the cut ends of sensory fibres are stimulated during thigh movements, the patient feels as if the sensation is arising from the non-existent limb. Sometimes, the patient might feel pain in the non-existent limb. Approximately 80–100% of individuals with an amputation experience sensations in their amputated limb. However, only a small percentage will experience painful phantom limb sensations (phantom pain). These sensations are relatively common in amputees and usually resolve within two to three years without treatment. Research continues to explore the underlying mechanisms of phantom limb pain (PLP) and effective treatment options. Signs and symptoms Most (80–100%) amputees experience a phantom limb, with some of them having non-painful sensations. The amputee may feel very strongly that the phantom limb is still part of ...

Psychophysics
Psychophysics is the field of psychology which quantitatively investigates the relationship between physical stimulus (physiology), stimuli and the sensation (psychology), sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and Sensation (psychology), sensation" or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the properties of a stimulus along one or more physical dimensions". ''Psychophysics'' also refers to a general class of methods that can be applied to study a perceptual system. Modern applications rely heavily on threshold measurement, ideal observer analysis, and Detection theory, signal detection theory. Psychophysics has widespread and important practical applications. For instance, in the realm of digital signal processing, insights from psychophysics have guided the development of models a ...

Behavioral Neurology
Behavioral neurology is a subspecialty of neurology that studies the impact of neurological damage and disease upon behavior, memory, and cognition, and the treatment thereof. Two fields associated with behavioral neurology are neuropsychiatry and neuropsychology. In the United States, 'Behavioral Neurology & Neuropsychiatry' has been recognized as a single subspecialty by the United Council for Neurologic Subspecialties (UCNS) since 2004. Syndromes and diseases commonly studied by behavioral neurology include: * Agraphia * Agnosias * Agraphesthesia * Alexia (acquired dyslexia) * Amnesias * Anosognosia * Aphasias * Apraxias * Aprosodias * Attention deficit/hyperactivity disorder * Autism * Dementia * Dyslexia * Epilepsy * Hemispatial Neglect * Psychosis * Stroke * Traumatic brain injury A traumatic brain injury (TBI), also known as an intracranial injury, is an injury to the brain caused by an external force. TBI can be classified based on severity ranging fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
