  • Relationship Between Attention Deficit And Hyperactivity Di

    Recent research now connects reduced regional volumes of the cerebellum with Attention Deficit and Hyperactivity Disorder. Stimulants are currently the most common method of treating this mental disorder, but what effect do they have on the brain and how are they subduing the symptoms? Attention Deficit and Hyperactivity Disorder, or ADHD for short, is a very common childhood mental disorder, with symptoms ranging from difficulty paying attention to general hyperactivity. Many previous studies have analyzed this mental disorder and have found correlations with a decreased size of the frontal cortex, along with abnormal activation of the basal ganglion; both of which help with cognitive processing and decision-making. While these may…

  • Cerebellar Dysfunction Essay

    Cognitive Effects of Cerebellar Dysfunction The cerebellum is regarded as an essential neural structure for motor control. At a tenth of the brain’s volume, it contains the majority of neurons in the brain. Many cortical areas project into the primate cerebellum; these include the primary motor and prefrontal cortices. Damage to the cerebellum is known to result in impaired motor function. Patients with cerebellar lesions may exhibit ataxia, unbalanced gait; dysmetria, lack of coordination in…

  • The Neuron Doctrine

    In essence, he proposed that the cerebellum is a principal agent of learning motor skills. He thought that the cerebrum recruited the cerebellum in order to automate its motor commands so that a relatively simple or incomplete command from the cerebrum would be elaborated and completed by the cerebellum after motor learning. Further, he proposed that the cerebellum is a site of learning because it contains many neurons and synapses, most of which are probably modifiable, and that absent…

  • Human Brain Vs Human Evolution Essay

    As the cerebellum began to grow, the complexity of cognition used to make tools also grew. Thus instead of having short, mode 1 tools that were very limited on the number of tasks that could be accomplished, later hominids, such as Homo heidelbergensis, possessed enough cognitive evolution to better adapt and change the way that they gathered food, by developing mode 3 tools, which were used to gather different ranges of food more efficiently. From a human behavioral ecology…

  • Alcohol Affects The Brain

    depending on specific factors. These factors include height, weight, gender and age. Alcohol affects a person’s brain, liver, and heart. Alcohol affects the brain by causing the neurotransmitters in the brain to relay information too slowly, and this makes a person who is drinking feel tired. The slowing down of neurotransmitters also trigger mood and behavioral changes that include depression and memory loss. A particular neurotransmitter is susceptible to small amounts of alcohol and it is…

  • Benefits Of Being Bilingual Essay

    definition of bilingual is to be “able to speak two languages with the facility of a native speaker.” Specifically focusing on bilingual people, how does currently knowing two languages benefit people through the economic and educational perspective? The knowledge of how a person knows the languages they speak fluently or are currently learning to speak all leads to the brain. The brain is the most complex organ in the human body. The brain can be separated into three units: the forebrain,…

  • Cerebral Palsy

    incapable of sending the appropriate signals that are necessary for muscle movement and coordination. The brain and central nervous system is composed of many structures that are responsible for sending signals to different parts of the body. One of those structures is known as the brainstem. The brainstem regulates vital physiologic functions, motor control, consciousness level, and is like an expressway for motor nerve axons traveling to the spinal cord from the cerebral cortex. The…

  • Jenbrassik Case Study

    1. The Jendrassik maneuver played a major role on the patellar reflex. One of the prevailing hypotheses has to deal with the alpha-gamma co-activation theory. It states that the alpha motor neurons activates the motor tone, which leads to the spindles providing feedback to the brain. This process is done by the gamma motor neurons, who are in charge of controlling the stimulation of the cerebellum. Also, both the alpha and gamma motor neurons meet at the same effector muscles. Furthermore, when…

  • Essay On Drinking At 21

    and the enjoyment one gets from being under the influence, 21 should remain the alcohol consumption age, because at 18-20 years old the brain is not fully developed, health risks are great, and every 15 minutes a teen dies du to drunk driving. In addition, the brain is not fully developed at 18-20 years old, furthermore it cannot tolerate alcohol and its terrible effects. The adolescent brain goes through several maturational processes that increase the risk of adverse side effects of alcohol…

    and gray matter work together how they enhance of the brain function. He explain how the gray and white matter get benefits from physical activity for that reason we need to consider to keep our first priority to do exercise that way we can keep our brain young. He also mention other researchers at the Beckman Institute the result of their study how older adults who do physical activity tend to have better brain function and they also increase their cognitive flexibility. How this adults can…
