Striatum

Parkinson’s disease By: Arielle Kim Approximately ten million people worldwide live with Parkinson’s disease, a chronic and progressive neurological disorder that affects the way you move. This disease can span from a couple years to one’s entire lifetime, worsening as time progresses. Parkinson’s is typically found from the age 60 and onward, but it can also affect people of younger ages. Parkinson’s disease has many symptoms that affect the human body and mind, but the five most recognizable…

Molecular control of adult neurogenesis in the human subependymal zone Adult neurogenesis The generation of new functional neurons from multipotent neural stem cells, termed neurogenesis, has been shown to persist in many mammalian species in two regions of the adult brain: the subgranular zone of the hippocampal dentate gyrus and the subependymal zone [SEZ, also subventricular zone] adjacent to the lateral ventricles [1, 2]. Lower levels of neurogenesis have been reported in other regions of…

in love up to seventeen months. The study had them view pictures of people they would recognize. They came to this conclusion, “intense romantic love is associated with activation of dopamine-releasing regions in the brain.” (Weiss 453) Like the striatum which is the pleasure center of the brain. The dopamine in the brain helps display various feelings. Therefore triggering the part of the brain that displays motivation. Hence the reason people think its a goal oriented state. The insula part of…

Elucidating the role of Heat shock proteins in poly glutamine (Poly Q) model in Dictyostelium discoideum . Introduction : Expansion of CAG trinucleotide repeats encoding poly glutamine (poly Q) tract in other wise unrelated proteins are responsible to atleast nine diseases . These diseases include Huntington’s disease (HD), spinobulbar muscular atrophy, dentatorubral pallidoluysian atrophy, and spinocerebellar ataxia (SCA) types 1, 2, 3, 6, 7, and 17.(1) Clinical features include ataxia and…

(Squire, 1992). Because implicit memory is unconscious and explicit memory is conscious, there are different mechanisms and anatomical locations involved. Explicit memory is known to be centered in the hippocampus whereas implicit is located in the striatum or basal ganglia (Packard & Knowlton, 2002). The mechanism of storing and losing long-term memories has been extensively studied.…

ADHD. The Biological view on ADHD views this disorder by tests ran by imagery research that shows how children with ADHD typically have several brain regions that tend to be smaller. The brain regions and structures include the pre-frontal cortex, striatum, basal ganglia, and cerebellum, and typically the overall brain size is about 5% smaller for children with ADHD. The biological view also focuses on the chemical differences in the brains of people with ADHD. Low levels of dopamine are…

Paul Pierre Broca talked about ‘le grand lobe limbique’ in 1878 or the great limbic lobe and used the term “limbic” (from the Latin limbus for border) to the rounded rim of the cortex which also has the cingulate and the parahippocampalgyri. However, its supposed role in emotion was elaborated by the American physician, James Papez in 1937 in the influential paper titled ‘A proposed mechanism of emotion’. This anatomical model is called the Papez circuit.[2] In the year of 1948 scientist…

Binge-eating is commonly related to low self-esteem and depression. This leads a person to compensate for feeling bad by eating large amounts of food at one time and then feeling worse about themselves afterwards. Stress can be a huge trigger to someone with a binge-eating disorder. Identifying the triggers will be an important factor when it comes to choosing which treatment will be most effective. Focusing on reducing the binges should be top priority. Eating healthy and exercising will be key…

Literature review It is a stark reality that as people age, their cognitive abilities tend to decrease, including memory capabilities. At the present, scholars have identified three types of memory stores: sensory memory, short-term memory (STM), and long-term memory (LTM). Memory includes primarily three processes: encoding, storage, and retrieval. Additionally, in order to these processes occur favorably, attention to the information or stimuli presented is vital (Garrett, 2011; Sternberg,…

Parenting can be one of the most stressful and hardest job. There isn’t a right or wrong way of parenting. If there was a right or a successful way of parenting, then there wouldn’t be so many different styles of parenting, ranging from the tiger parenting, helicopter parenting, and the hippie-style parenting. Every parent wants to raise their children the best way possible and to guide them to succeed in life, however, there are some parents who push the bounds of ethical parenting to an…
