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…

Do we really use only 10% of our brain capacity to function in everyday life? It really depends on self opinion. Some of us may think we use more of our brain when we are working and some of us may think that when we are relaxing our brains are relaxing as well. There is no scientific theory behind how much we use of our brain. Most of us use our brains daily, to think, to react, to sense feelings, etc. You may be surprised on how much we use our brains each day. Its always active, axons are…

State one of three descending control of pain system. (1pts) 1) The prefrontal cerebral cortex projects to the central gray region of the mesencephalon 2) The central gray projects to the raphe magnus and the nuc.

It is an important and interesting question on how feelings and emotions emerge inside our human bodies. It is a known and general fact that emotions come from the brain, yet it is also evident that specific areas of brain are responsible for productions of feelings. In order to better understand the production mechanism, it is vital to get deeper into the brain’s emotional map and examine particular areas. One of these specialized areas of central interest is the amygdala that is responsible…

In the world today, there are about 5000 languages spoken. Where the languages originated from is the unknown factor that the humans have been studying for the past two centuries. Experts have linked the similarity of languages by the shared words, sounds, or grammatical constructions. There are specific names classified for people who speak a certain number of languages. People who speak one language are termed monolinguals. People who speak two languages fluently are termed bilinguals. People…

It’s two hemispheres control everything from voluntary movements to cognitive and emotional processes. The corpus callosum, a bundle of nerve fibers, holds these halves together. The right and left hemisphere in the cerebrum controls two completely different things. Roger Sperry, a neuropsychologist, produced some ground-breaking work with the these two hemispheres in the 1960’s. He tested on an epileptic patient who had his corpus callosum severed. He discovered that the two hemispheres work…

Inside out Developmental Psychology Paper The brain is the most complex part of the human body. The brain can be divided into three basic units, the forebrain, midbrain and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem and the ball of tissue is called the cerebellum. The hindbrain controls the body’s vital functions such as heart rate and respiration. The cerebellum coordinates movement and is involved in learned routine movements. The upmost part of the…

The system is what makes up our body, it's the foremost sophisticated of the various systems within the body, and it's conjointly a network of nerve cells and fibres that transmits nerve impulses between components of the body. This essay will explore the structure and functions of the system similarly as well as looking in depth at the neurons and how they communicate The system is split into two components, the central nervous system- which incorporates the brain and also the spinal cord. The…

Why do children we all once loves so dear, become cold hardened criminals and later delinquents?.The truth is, a host of issues contribute to antisocial and criminal behavior. Sometimes, things happen that a mother cannot help. Emergencies during pregnancy or delivery may cause the doctor to have to perform an emergency extraction of some type to the fetus. Surprise! such a procedure may make the young newborns susceptible to antisocial personality. In add to birth complications, unfortunate…

There are 4 main types of memory that would be lost: episode memory, semitic memory, procedural memory, and working memory (Memory of Biology 29) Alzheimer’s is also related to the Cerebrum, and there are two hemispheres(World of biology 5). The Corpus Collosum, which is the left hemisphere of the brain, is significantly larger than the right side of the brain and sensory information is transmitted within it. (World of Anatomy 10) and ultimately connects to the spinal cord. There are four types…
