Occipital Lobe Analysis
If the Occipital Lobes were destroyed or if we didn’t have that specific one lobe will we be able to do everyday matter? What will be the result? How can the brain tell what colors each and everything is if it is inside the skull?

I chose and found this project interesting because there are a lot of functions in the brain and how everything processes. It is more interesting how we see things with our eyes, but actually comes from the brain. Most people wonder how the brain sees everything since it is in the skull, how the eye signals everything to the brain, and how the colors appear. The more you research and find out how your body actually functions you will get as interested as me and dig into the matter to find out more. That is how I came across to searching

There are many types of disorders that happen with this particular lobe such as
1. Visual Hallucinations: Seizures may happen in the occipital lobe, which can cause visual hallucinations. The person may see rapid blinking, colored lights or flickering lights. (When you’re in the sun for a long time and then come to a place where there isn’t any sunlight)
2. Visual Illusions: Distorted perceptions which can take the form of objects appearing larger or smaller than they already are, objects lacking color or objects that have abnormal coloring.
3. Visual Object Agnosia: A person with visual object agnosia can see familiar objects, but when asked to identify the objects, she can’t recognize them. Visual object agnosia occurs when there is damage to the right hemisphere occipital lobe and left hemisphe re occipital lobe (mutual damage).
If both right and left hemisphere of the occipital lobe are damaged you will become blind. If any damage occurs in another part of the brain, some might turn out to be colorblind ,this means they will not be able to see colors, it will be a grayscale for

    Visual agnosias is the inability to recognise familiar objects presented visually. There are two types of visual agnosias- Apperceptive agnosia and Associative agnosia. Apperceptive agnosia is the physiological type of visual agnosia, where it is a failure of recognition due to damaged visual perception. Associative agnosia is the developmental type. It is where perceptual ability is intact, but it shows difficulty in recognising familiar objects because of a failure in accessing relevant knowledge from the person’s memory.…

    There are many cognitive functions that the brain performs on a daily basis. People can survive with traumatic brain injuries or strokes and still function to a point. The brain is an amazing organ that can be resilient and bounce back from brain injuries due to an accident or stroke, depending on which areas of the brain are affected. If certain areas of the brain are affected then the person could lose the ability to see, speak, remember, function, or even die. A person’s brain continues to change and develop throughout their lifetime, even if parts of the brain become necrotic due to dementia and other disorders. The best known case of how a person can survive and have a relatively normal life after a brain injury was Phineas Gage. His story is an amazing one that is hard to believe.…

    There are three major brain divisions. They are the cerebrum, the brainstem, and the cerebellum. The cerebrum contains 40% of the weight of the brain and is founded in the superior part of the brain. This portion of the brain has many functions and lobes which perform certain functions. The frontal lobe is involved with “activating and controlling both fine and complex motor activities.” This involves speech. It is also involved with the executive functions, such as reasoning and rationalizing, among others. The occipital lobe is concerned with vision and processing the information received from the eyes. According to the reading, the “key functions of the parietal lobes include perceiving and integrating sensory and perceptual information,…

    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.…

    An optical illusion (also called a visual illusion) is characterized by visually perceived images or views that can differ a ton from objective reality. Optical illusions have been around for centuries, teaching us that you shouldn’t fully trust your senses due to that we can easily be tricked. However, optical illusions can help us learn how easy it is to trick our brain to see an object that seems real but is really not. An example of a well-known visual illusion would be the “Ames Room”. An Ames room is a distorted room that is used to create an optical illusion that uses depth and perspective to make it seem like the room is the same when it actually has been manipulated. This illusion is one of the top and most famous optical illusions…

    A sudden surge of electrical activity in the brain that affects how the person feels or acts for a short period of time are called seizures. Seizures not being diseases are more like symptoms of many disorders that can affect the brain. Most seizures are noticeable, and then there are some of those that can’t really be seen or are hardly even noticed. Based on prior knowledge and real observations, people who suffer from epilepsy is usually either really outgoing, or they really keep to themselves. The seizures in epilepsy may be related to a brain injury or a family tendency, but often the cause is completely unknown. The word "epilepsy" does not indicate anything about the cause or severity of the person's seizures (http://www.epilepsy.com/101/ep101_seizure). Symptoms of an early seizure or epilepsy include déjà vu, visual loss or blurring, racing thoughts, stomach feelings, strange feelings, tingling, fear or panic, dizziness, headaches, blackout, stiffening, eyes rolling, confusion, shaking, heart racing, twitching movements, etc.…

    Hallucination

    Hallucination is defined as the perception of an object or event (in any of the five senses) in the absence of an external stimulus. Visual hallucination is a kind of sensory misperception. Although visual hallucination is not pathognomonic of a primary psychiatric illness, it is still a primary diagnostic criterion for various psychotic disorders. People with visual hallucination usually are recommended to seek for psychiatric consultation. Three common approaches are suggested to explain the causes of visual hallucination including disturbance of brain structure, neurotransmitters and emergence of the unconcious into conciouness. The common causative mechanism are irritation of cortical centers responsible for visual processing, lesions that lead to cortical release phenomenon and that affecting the reticular activating system.…

    Hemineglet

    • 2 Pages

    A Neurological syndrome is any disorder in the nervous system of the human body. One example of such disorder is the Hemineglect Disorder where one hemisphere of the brain is damaged causing a deficit in attention or awareness, whereas patients tend not to pay attention to the left side of their bodies. As strange as that might sound, patients with this disorder do not take knowledge to objects on the left, therefore they ignore every part of their body on that side. The symptoms of this syndrome can be quite noticeable; most patients who have this ignore stimuli to the left as opposed to the right side. For example if one is talking with a group of people that person does not pay attention to the people on his or her left, only the ones in front of or to the right. This is not mean that the person does not care about the person on the left but rather their brain does not allow them to acknowledge the person on the left. Such things as talking to someone and ignoring have a reason, due to a neurological syndrome, this does not mean they are blind but rather that the right side of their parietal lobe is damaged as caused by a stroke or any other medical problems. A neglected patient is unable to make the right neural connections in the reticular causing them not to process information as images or pay attention. The main cause is due to an injury such as a stroke in the right parietal lobe, because the right side is the main source of vision aspects or “searchlight’ to the left side and also the right side of the human eyes. As for the opposite side of the parietal lobe has the control of the right and also the ability of language. Moreover if the right side of the parietal lobe has been damaged it looses its searchlight entirely but the left side only compensates the right side of the vision since it has the ability to, making the patient only be able to notice the right side of the world. Many neglected patients will also be unable to…
