Visual Object Agnosia And Prospopagnosia
Visual Object Agnosia and Prospopagnosia
Visual Object Agnosia
Visual agnosia is a deficit in recognition that is not due to impairment of vision or memory.[1] Apperceptive recognition includes the visual information from the retina being put together to create a perceptual representation while associative recognition means the meaning of an object is attached to the perceptual representation. If someone can perceive the form of an object and has knowledge about it but cant identify it, this is associative agnosia.[2] However, if they are unable to recognise it because they cannoy perceieve the form, it is apperceptive agnosia. Visual agnosia is generally due to bilateral damage in the posterior occipital and/or temporal lobe/s in the brain.

    I asked John is he had any medical problems with his eyes which he replied, “No.” I explained to him that I was going to use my pen as a stimulus and he needed to follow the pen with his eyes and eyes only. He stated he understood my instructions. When I moved my pen, John did not move his eyes or his head. John just continued to stare at me as if he did not understand what to do. John was advised again to follow my pen with his eyes. I observed a lack of smooth pursuit in both eyes. There was a distinct and sustained nystagmus at maximum deviation in both eyes. I also observed prior to forty-five (45) degrees in both eyes also. The next test I administered was the Walk and Turn.…

    The Man Who Mistook His Wife For A Hat Summary

    In this chapter Jenni Ogden describes the case of Michael, a young man who crashed while riding a motorcycle. Afterwards he sustained many injuries to his body and his brain, because of his bodily injuries and Michael’s appearance of normality the doctors focused on his external injuries and did not focus on his brain. Later Michael went blind and was eventually diagnosed with visual object agnosia. Ogden then gives a brief broad history of agnosia and describes the three types: visual, auditory, and somatosensory. Different types of visual agnosia are then mentioned to give the reader a deeper understanding of Michael’s condition. Ogden then illustrates the different neuropsychological evaluations that Michael underwent: he was asked to describe pictures, read, recall…

    Brain BehaviorA1

    Goodale and Milner added to the research of Ungerleider and Mishkin; they proposed that the spatial and structural attributes of an object are processed by both streams but for different purposes. Instead of Ungerleider and Mishkin’s “what vs. where” proposal, Goodale and Milner suggested using “what” and “how” to describe the roles of the ventral and dorsal streams. They suggest that the ventral stream plays the major role in composing the representation of the visual world and objects within it (what).These representations play an important role in identifying objects and allowing us to attach meanings to them. Goodale and Milner also proposed that the dorsal stream is responsible for the visual control of actions directed at those objects (how) and not just to identify spatial localization of objects. As Dr. Marrotta stated: “Goodale and Milner’s research focuses on behavioral output rather than a separation of sensory input.” Goodale and Milner supported their findings by examining and observing the behavior of numerous patients…

    Aesthesi What Is Synesthesia?

    Synesthesia is a condition in which one sense (for example, hearing) is simultaneously perceived as if by one or more additional senses such as sight. Another form of synesthesia joins objects such as letters, shapes, numbers or people's names with a sensory perception such as smell, color or flavor. The word synesthesia comes from two Greek words, syn (together) and aisthesis (perception). Therefore, synesthesia literally means "joined perception."…
