  • Cerebellum And Basal Ganglia Case Study

    In the past it was believed that the cerebellum received information from various areas of the cortex and projected information to the primary motor cortex via thalamus, thus fine-tuning a movement (19). It was also believed that the Basal ganglia was involved with the inhibition and selection of action commands (19). These views suggest the involvement of both cerebellum and Basal ganglia(BG) in purely motor function. But that is not the case, recent studies have found a connection between the BG and cerebellum and projections from these areas to the cortex through the thalamus. Premotor, prefrontal, temporal and parietal cortices are the areas that receive projections from the BG and the cerebellum implicating its involvement in non-motor…

  • Basal Ganglia

    Walking is assisted by the brain, spinal cord, muscles, reflexes and receptors. The act of walking begins from brain and spinal cord which is the planning on how to walk. More precisely, it starts from the cerebral cortex. Cerebral cortex is the region of decision-making and it initiates voluntary response, in this case, the act of walking. Basal ganglia are also responsible for voluntary locomotion. It requires the knowledge of the body’s position in space (where am I walking to) and what…

  • Parkinson's Disease And Body Movement

    The basal ganglia plays a vital role in the way movement happens and when dopamine does not follow the path that it is suppose to, it hinders body movement. Parkinson’s disease is often known as PD and it is a progressive neurological condition, which means the sickness and symptoms get more severe as time goes on (Noble, 2007). Out of all the neurodegenerative disorders, PD is the second most common one (Noble, 2007). It happens amongst 1% of the population older than sixty years. (Samii,…

  • Parkinson Disease History

    History Parkinson disease was coined by James Parkinson, an English apothecary surgeon, political an activist, paleontologist and geologist in 1817. He described the disease as a shaking palsy that involves resting tremor, diminished muscles strength, paralysis, unusual posture and gait, and how it progresses overtime. Sixty years later, Jean Martin Charcot, a French neurologist and professor of anatomical pathology, also the founder of modern neurology. He clearly defined the disease as a slow…

  • Advantages And Disadvantages Of Dual Tasking

    neurological condition that is caused when the substantia nigra cells in the brain die (NHS,Causes of Parkinson's, 2015), which means that the neurotransmitter called dopamine, that is released by the dopaminergic neuron, and other transmitters are not getting produced. By the time of diagnosis over 80 percent of the dopaminergic neurons in the basal ganglia have died which would cause movements to slow down as the person would find it hard to start moving (R.Mc.Ardle. In total, a healthy human…

  • The Effects Of Huntington's Disease

    Huntington’s Disease Huntington’s disease is one of the most dreaded diseases among the group of genetic diseases. Huntington’s affects the basal ganglia portion of the brain it is reasonable for a person’s motor functions. Over time huntingtin’s destroys this area. The disease’s name is derived from the ancient Greek word dance. It is named this because after the portion of the brain is partially destroyed, the person walks with an unintentional sway, an almost dance like movement. (Blachford)…

  • Hypoxia Case Study Essay

    dyspnea. This patient has a mast medical history of Parkinson’s disease, which according to Dr. Bautista and Dr. Grossman is a progressive movement disorder related to the basal-ganglia of the brain, which control movement of the body. At the end of the substantia nigra of the basal ganglia lies the pathway to muscle cells that use dopamine as the neurotransmitter (Bautista & Grossman, 2014). This nigrostriatal pathway is disrupted in Parkinson’s disease, and 70-80% of the neurons need to be…

  • Chore Chorea Symptoms

    control movement. Skeletal muscles are activated when signals sent from the primary motor cortex cross the body’s midline. This stimulates the opposite side of the body, which means that the left hemisphere controls the right side of the body and vice versa. Many motor problems can occur when the primary motor cortex is damaged. Random, inappropriate movements can occur when the primary motor cortex is not functioning properly. Chorea can occur from many causes, but can be a consequence of…

  • Personal Narrative-Ontogenetic Explanation

    stuttering appeared to be caused by damages in the left inferior frontal cortex. Research methods - Imaging studies: For this part, I will focus on two types of imaging methods, MRI (Magnetic Resonance Imaging) and FMRI (Functional Magnetic Resonance Imaging). They are both used to study the brain activity during a specific task. MRI provides a static image of the brain while FMRI provides a dynamic image of the brain. For this event, I chose a study that used FMRI to investigate the…

  • The Human Body: The Peripheral Nervous System

    “[playing] a role in motor control as well as our reward system” as chemical synapses release dopamine into our neurons (Blumenfeld, 2010). Though there are multiple neurotransmitters that play a role into our neurological health, dopamine is “…involved in a large range of affective, motor and cognitive functions, many directly or indirectly mediated by the prefrontal cortex” which, in simple terms, controls most of our functions in the nervous system (Meisenzahl et al., 2007). In a healthy…
