Its five main regions help regulate basic life processes, including breathing, pulse, arousal, movement, balance and sleep and the early stage of processing sensory information. The central core consists of the thalamus which relays sensory and motor signals to cerebral cortex, the pons which relay signals from the forebrain to the cerebellum, the cerebellum which deals with motor control, the reticular formation which deals with multiple tasks such as regulating the sleep-wake cycle and filtering incoming stimuli to discriminate irrelevant background stimuli, and finally the medulla which contains the cardiac, respiratory, vomiting and vasomotor centers and so deals with the autonomic (involuntary) functions of breathing, heart rate and blood pressure. (The Central Core, Discovering Psychology) The limbic system exists only in mammals. Its regions mediate motivated behaviours, emotional states, and memory processes. The limbic system regulates body temperature, blood pressure, blood sugar level, and other housekeeping activites.
What Doctor MacLean suggested was that through evolution the brain, along with all of the organs of our body, began to evolve and become more complex. Through this evolution a new brain was formed over the older brain, this continued until we had three brains each responding to the needs humans obtained as they evolved. The first brain we acquired is the Reptilian Brain, also known as the physical brain. The second brain is the Limbic System, or the emotional brain, and the third is the Neocortex, which is your thinking brain. Let’s start with our first brain: the Reptilian Brain.
Lastly development is based on a sequence series of events that build off the previous. Motor development is the ``sequential, continuous age-related process whereby movement behaviour changes`` across a lifetime (Getchell & Haywood, 2005. p. 5). The paper will examine the effects of each disorder on motor development to determine whether both cognitive and motor deficits are commonly associated with it. Across a lifespan motor development begins rapidly as a child and then plateaus once adulthood is reached. In a normally progressing child these changes occur in an orderly sequence.
Briefly describe the function of myelin and discuss the neuropsychological impact of one disorder which causes demyelination. The human nervous system (NS), encompasses the brain, spinal cord and the peripheral nerves (PNS), is arguably the most diverse of machines due to the structure and complexity of its organisational functions. Fundamental aspects of the NS are the connections between the structures, functions and the flow of information where cells are organised as networks and circuits to process information (Thibodeau & Patton, 2005). The brain and the spinal cord make up the central nervous system (CNS) (Thibodeau & Patton, 2005), where axons, nerves and neurons serves essential purposes. Oligodendrocyte produces a white substance call myelin that insulates the axons (Gross, 2009); destruction to the myelin consequently produces diseases called myelin disorders which results in demyelination (Thibodeau & Patton, 2005).
* Parietal Lobe – Responsible for sensory information from the body, also where letters are formed, putting things in order and spatial awareness. * Occipital Lobe – Responsible for processing information related to vision. * Cerebrum Lobe – biggest part of the brain, responsible for memory, attention, thought and our consciousness, senses and movement. * Hippocampus – Responsible for memory forming, organizing and storing emotions. 3) – Explain why depression, delirium, and age related memory impairment may be mistaken for dementia Depression, delirium and age related memory impairment may be mistaken for dementia because they all share many of the same symptoms as dementia.
The pons connects the medulla with the cerebral cortex. The spinal cord’s neural network is dependent upon the reticular formation’s filtration of irrelevant sensory stimulus. This region relays signals to the thalamus, cerebral
The purpose of this paper is to explore the medial temporal lobes purpose. The medial temporal lobe, also called the MTL, is responsible for creating memories. It is also responsible for more than those functions associated with memory. In the past, research has concluded that the medial temporal lobe of the brain is primarily used for memory processes. (Eichenbaum et al., 2010) The medial temporal lobe is the lower lateral lobe of either cerebral hemisphere, located in front of the occipital lobe and containing the sensory center of hearing in the brain.
Throughout the rest of history the circulatory system has continued to go through considerable and momentous reformations. All vertebrates now possess an endothelium. During the divergence of urochordates and cephalochordates, was when researchers first found the endothelium to appear, which leads some scientists to believe cardiovascular evolution really began somewhere closer to five hundred million years ago. Next scientists pondered why the endothelium was advantageous or beneficial to early vertebrates. Many have hypothesized
The cortex is divided into two hemispheres, left and right which are connected by a thick layer of cells called corpus callosum. Other parts of the brains are also divided laterally. (Broadbent,1977) Both the sides of the brain are different in terms of cognitive functions they execute. The main difference is the fact that right brain controls the left side of the body whereas left brain controls the right side of the body. Definition: The theory of the structure and functions of the mind suggests that the two different sides

It encompasses several intermediary stages such as birth through infancy, childhood, adolescence, young adulthood, and late adulthood to death. However, not all changes that occur in the life of an individual can be considered as development. Therefore, development involves a continuous and systematic pattern of changes that can be grouped into three broad categories. These changes include; physical development, cognitive development and psychosocial development (Sigelman & Rider 2006, pp.2-3).
