¶ … prefrontal cortex and limbic system in the play years. What are their functions? How do they differ? What changes occur in a child's behavior as a result of a maturing limbic system and prefrontal cortex.
The prefrontal cortex and the limbic system are very central in the early childhood development and in particular during the play years of the child. The prefrontal cortex is responsible for the triggering of the spontaneous activities, initiating drive in the growing kid, keeping the kid active and helping in the coordination of the movements and behavior (Michael H. Thimble, 1990). These are very significant aspects for a growing kid. On the other hand, the limbic system is the brain area that is very important especially in the regulation and expression of emotions. The limbic system is divided into three major portions as the Amygdala; which is a tiny part of the brain that is responsible for the registry of emotions. Hippocampus; is responsible for the processing of memory and in particular the memory of locations. Hypothalamus; this is the brain area that responds to the Amygdala and the hippocampus and in effect produces hormones that activate the other parts of the body and brain into activity (Cassie Landers, 2012).
A maturing of the limbic system and the prefrontal cortex will see the child having more coordinated movements, ability to balance...
Describe the process and timing in which prenatal, phenotypical sex determination occurs. Identify any chromosomes, genes, and hormomnes that might be involved in that process. What are the Wolffian and Mullerian processes, and what roles do they play in the development of male and female sex organs.
The human male determination is marked at about five weeks of the gestation with the differentiation of the testis. At this stage, the embryonic testis produces testosterone and the Mullarian. The Mullarian are powerful hormones that divert the developmental pathways particularly along the male lines. Here, the testis determining factor helps in the switching of the genital ridge (the indifferent gonad) to testis differentiation by the action of the genes. There are a number of genetic accidents like the lack of mutation of TDF or inhibition of the actions of the testosterone that can alter the male determination pathway, resulting into a phenotype of the baby being female. The male development is known as the "default pathway" and female commonly referred to as "mutant males" (Jennifer S. Marshall, 2012).
The function of the Wolffian and the Mullerian is particularly observable 15 days after…
In short, the left prefrontal cortex is intimately connected to the cingulate cortex, the source of attentional ability (e.g. Kalish, Wiech, Hermann, & Dolan, 2006), whilst simultaneously serving as site for happiness. The hypothesis of this essay, therefore is, that the greater the span of attention accorded an activity, the more positive and more intense the level of serenity experienced. Although Csikszentmihalyi has conducted research on 'flow' and shown that the
Decision Making, Impulse Control, And Cognitive Development Cognitive development entails the development in children with respect to processing of information, conceptual resources, skills in perception, learning the language and development of the brain. Piaget and Vygotsky advance theories explain cognitive development in children. These theories are similar in some aspects, yet they still differ about issues (Nakagaki, 2011). Piaget gives four stages to explain cognitive development whereby he advances that each
Theoretical Perspective of the Biological Approach to Personality Psychology Personality is defined as a person's exceptional deviation on the general evolutionary design for human temperament. A personality trait refers to a durable disposition to act in a certain manner in different situations. Personality traits represent some of the most significant sets of individual disparities in organizations. It is the comparatively set of psychological characteristics that differentiates one person from another. People
Bipolar Disorder Symptoms Bipolar disorder has been studied for more than a decade after remaining undiagnosed in children and adolescents for many years. Much literature such as that by Pavuluri, Birmaher, and Naylor (2005b), and Kowatch and Debello (2006) is available on diagnostic issues pertaining to paediatric bipolar disorder. In addition, many cases studies have also been published on the topic such as those by DuVaI (2005) and Hamrin and Bailey
Cognitive Effects of Brain Injury and Disease The care of patients with brain injury and diseases has improved substantially over the last thirty years. Nonetheless, the acute cognitive effects caused by brain injury are still a problem for the survivors. Such impairments are substantial contributors to functional disability after brain injury and reduce quality of life for affected persons and their families (Schultza, Cifub, McNameea, Nicholsb; Carneb, 2011). Accordingly, it is
function of the brain as it relates to psychology. Understanding the function of the human brain is critical in understanding how and why people think and act the way they do. Studying the brain can also explain many different types of behaviors, such as emotions, stress, and even the development of language, and all of these are extremely useful in the study of psychology. The brain is divided into four
