    within D.F.’s lesions site—the ventrolateral occipital region. Thus, D.F. produced no activation in this area. Instead, D.F., showed activation in other areas which suggests, “[her] capacity to recognize color and grayscale pictures of objects is dependent on spared regions of the ventral cortex, including the primary visual cortex and extensive areas of the lingual and fusiform gyri” (James et al., 2006). Research by Podrebarac (2013) supports this finding, suggesting, “visual shape information is processed within the LOC, while texture is processed in medial regions of the collateral sulcus (CoS)” (Podrebarac, 2013). Moreover, because “the perception of color in humans has been associated with activation of a ventromedial occipital area (in the collateral sulcus or lingual gyrus)” (Ungerleider & Haxby, 1994) this explains D.F.’s ability to discriminate color and texture despite sustaining damage to LOC. Moreover, these structures are acting like the LOC in healthy controls (James et al., 2006). Furthermore, albeit capable of processing color and texture, D.F.’s ability to discriminate between shape and size is impaired due to its functional location in the ventrolateral occipital region. In Experiment 2, patient D.F displayed bilateral activation in the same structures as healthy control participants; as was expected. However, unlike the healthy control participants, “D.F. did not show activation in the superior parieto-occipital sulcus, […which] has been shown to be…

  • Temporal Lobectomy Case Study

    patients with temporal lobe epilepsy there is a high resistant to medication. This leads to a risk of memory impairments and mood disturbances. Long-term this leads to quality of life impairments and an increased risk of death. Due to the resistant to medication surgery is recommended for patients with TLE. Anteromesial temporal lobectomy (AMTL) is the most common surgery for the treatment of patients with TLE. AMTL is performed in both children and adults. AMTL is done in 30-40% of surgery…

  • Would We Live Without The Brain Essay

    all the effort the brain the human body wouldn’t be completed. You will learn that the brain is broken into parts, it’s the cerebrum, cerebellum and the brain stem, they all have their job within the brain; the cerebrum breaks up into four parts the Frontal lobe, Temporal lobe, Parietal lobe, and Occipital lobe these lobes have important parts that work with the human body. The brain is vast with knowledge and information, and it’s been said that the human race only uses about ten percent of…

  • Chief Complaint Case Study

    There is significant white matter changes, which is rather confluent, especially in the parietal occipital lobes. At this point, I doubt that this is progressive multifocal leukoencephalopathy, as she is not immunocompromised. It is not consistent clinically with posterior reversible encephalopathy syndrome, as she does not have any marked hypertension and there is no headache, confusion or visual changes. She is too old to be suffering from most of the leukodystrophies. At this point, I do…

  • Phineas Gage's Role In Cognitive Function

    The frontal lobe of the brain is responsible for decision-making abilities, problem-solving, control of behavior, consciousness, and emotions. More important parts of the brain include the parietal lobe, the temporal lobe, and the occipital lobe. The parietal lobe functions as the processor of sensory information and works to control a human’s ability to understand spoken language. The temporal lobe’s primary functions are speech, memory, auditory perception, and emotional responses. The…

  • Human Brain Case Study

    Dyslexia, Apraxia, and Gerstmann syndrome are a few examples of medical problems associated with damage. Unlike the other lobes, the occipital lobe is responsible for one important task. Visual processing is its job and is divided into several functional visual areas. Located at the complete back of the brain, the lobe resides under the occipital bone. Damage to the occipital lobe can result in some major medical problems. Occipital lesions can cause visual hallucinations, vision cuts in each…

  • The Cerebrum

    separated into two hemispheres, the right and the left hemisphere. It is divided into four different parts: the frontal lobe, the parietal lobe, the temporal lobe, and the occipital lobe. (See annexe 1) The first lobe is the frontal lobe; the frontal lobe controls your creativity, your problem solving, your judgement, your intellect, your attention, your behaviour, your coordination, your smell, and your personality. The second lobe is the parietal lobe; it processes information like pain,…

  • Reflective Essay On The Brain

    (brainstem) to the top (cortex); from least complex to more complex. When the brain begins to develop it starts with the brainstem where it is found at the bottom of the skull and controls the heart rate, blood pressure, and body temperature. Next would be the midbrain which is found at the top of the brainstem and it controls motor activity, appetite, and sleep arousal responses. After the midbrain comes the limbic system it is found in the most inner, central portion of the brain or cortex.…

  • Suspension: The Use Of Concussions In Professional Football

    hit hard enough then brain injuries may still occur (WebMD, 2015). A concussion can cause damage to many parts of the brain, but I would like to go into more detail of the gray matter and cerebral cortex and how those can be affected the most. The gray matter holds the majority of the brain 's neurons in the cerebral cortex (Mastin, 2010). Our memories, perceptual awareness, thought, language, and consciousness are all housed in our cerebral cortex. This is displayed throughout all four of…

  • Human Brain Vs Human Evolution Essay

    the growth of the neocortex; which is involved in higher functioning processes such as sensory perception, generation of motor commands, spatial reasoning, conscious thought, and language. This can explain much of our unique behaviors in language, religious rituals, spatial reasoning, motor commands, etc. An example of the importance of the growth in the neocortex is the development of the Broca’s area, located near the frontal lobe, which has allowed hominids to develop speech functions. Based…
