drinks. Studies suggest the drug increases wakefulness and apparent alertness due to the effects it has on one’s body - caffeine is absorbed within a period of 45 minutes after ingestion, and binds to adenosine receptors located in the central nervous system, blocking the neurotransmitter adenosine which causes neural activity - the rate of firing of central neurons - to slow. Since adenosine is unable to bind to the receptors, the neurotransmitter is unable to slow neural

Association (AOTA), Society for Neuroscience, and the American Congress of Rehabilitation Medicine. Motor rehabilitation is premised on the belief that behavior (e.g., practice and motor-based intervention) forces neuroplastic changes in the central nervous system (CNS) which lead to better motor function. According to Richards, Hanson, Wellborn, & Sethi (2008b) the current evidence supports that "repetitive behavior that produces motor skill acquisition does

In this paper I am going to discuss Parkinson’s disease. I will explore what the disease is, symptoms, treatment, and prognosis. Parkinson’s disease is a neurodegenerative disease of the central nervous system. It is present in mainly elderly patients (male and female) but there is an early onset in younger children if it is genetic. This disease occurs when nerve cells in the brain (substantia nigra) that produce dopamine are destroyed. It is unknown what causes these cells to die. Once the majority

Critical Thinking Assignment 1 Kim McLaughlin 01/26/2014 Abstract Our senses both enlighten and deceive our mind. Our senses act as a liaison to the world working hand in hand to shape our perception of who we are, where we are, and what is going on in our surroundings. Our senses nourish our brain a lot like food nourishes our body; without them our brain would be virtually blank. Provide at least three (3) reasons for believing in the accuracy or inaccuracy of sensory information. Our

legRunning Head: Should marijuana be legalized? Should marijuana be legalized? Should marijuana be legalized? There are various reason why people smoke or have smoked marijuana. The reasons may range from extracurricular drug use medicinal uses and anywhere in between. The positive effects medical research states marijuana can assist with cancer patients and terminally ill individuals, but only for pain reduction and appetite increases. In the case of glaucoma the pressure from the eyeballs

of diabetic retinopathy, age and hypertension also causes changes in the structural geometry of retinal vessels. Diabetes may cause retinal abnormalities which is known as diabetic retinopathy, abnormalities in kidneys (diabetic nephropathy), nervous system (diabetic neuropathy) and is known to be one of the major risk for cardiovascular diseases. Diabetic retinopathy is a microvascular complication caused by diabetes which can lead to blindness. There won’t be any visible signs in the early stages

attack their fine motor skills in a way where it is hard for them to function. In young children, gross motor, fine motor, and cognitive development are intertwined processes related to the maturation timetables of the central and peripheral nervous systems. Neurons are migrating, proliferating, and making more complex connections. Children become capable of more sophisticated communications with the production of neurotransmitters. Myelination, the sheathing of neurons in protective layers of fatty

The Nature Versus Nurture of Cognitive Development The brain is the central control for the human body; it receives, organizes, and responds to all stimuli that are detected outside and within the body. However, what makes the human brain superior to all other organisms is its ability to carry out cognitive processes of which less complex organisms are not capable. As Myer states, “cognition refers to all the mental activities associated with thinking, knowing, remembering, and communicating”

hallmark of critical periods. As the brain ages, however, it becomes less “plastic,” or easily modifiable, marking the closure of critical periods. While this decrease in plasticity is a key step toward the maturation of communication networks in the nervous system, researchers realized it might be possible to reopen critical period windows to improve sensory development in people who experienced early sensory deprivation. http://main.zerotothree.org/site/PageServer?pagename=ter_key_brainFAQ The
