Article Review The Teenage Brain - Essay Example Casey. Ben Luna stated that an adolescent brain acts like an adult brain by overusing the frontal lobe. The onset of adulthood is associated with the integration of frontal lobes with other areas of the brain and myelination is just part of the process. Meanwhile, the US National Institute for Mental Health argue with the studies stating that brain size, folding, and regional specialization started at age 12; instead, the institute indicate that an adolescent brain has a long way to reach the adulthood. Jay Giedd of the National Institute for Mental Health found out that grey mater thickens in childhood and thins from back to front during the early adulthood. This process completes early in girls and Giedd explained that it was probably the reason why girls mature early than boys. Giedd thought that the thinning of the grey mater is due to the synaptic pruning and that more environmental guidance will be better for the adolescent’s behavior. Elizabeth Sowell warns other researchers like Giedd against making direct connections between brain changes and specific teen behaviors as there are no supportive data to prove the assumptions. Tomà ¡Ã… ¡ Paus agree with Sowell in not treating brain-behavior relationship as a one-way street but also agree with Giedd that brain maturity continues beyond the first 3-5 years of life. George Bartzokis stated that as grey mater thins, the white mater gains with layers of insulating myelin with the maximum myelination responsible for the wisdom an adult has. Abigail Baird and Greg Bennett relate gained of white mater to the ability to empathize and B.J. Casey that the amount of reward distinguish the strong nucleus reaction of the brain seen among children or adolescents (Powell, 2006, 865-867).

LAB 15 - Assignment Example The remodeling of the skeletal remains had not occurred because of the teeth loss was around 6 to 18 years. It is because the teeth were absolutely erupted. It is still approximately 18 years because this is the stage of the Basilar Suture. The complete fusion of the teeth was around two years which led to the complete permanent eruptions by the 18 years. The skeletal disjoint of the bones that led to the separation of the bones to pieces had to take around 6 years because the basilar bone has fused to form the occipital condyles. The identification of the skeleton remains is determined generally by creating a biological profile of the remains. In the four remains they are well identified by the age, sex, statue and the ancestry of the bones. The bones are also identified by the diseases that attack them. This is also determined by the injuries the human remains might have faced before in history. The first information given by the forensic analyst is whether the remains are bones and if the bones are for human beings. It is hard to identify the remains if it is covered by some substances that affect their shapes and mechanisms. The substances can be Ceramic shards, woods, rocks and concrete. For the forensic analyst to be sure if the remains is a bone, he or she ensures that the remains are well cleaned and examined very clearly. If the remains are bones then it is chance to understand whether they are from human beings. For the mammals their bones are all almost in the sale location and well shaped. By havi ng a skull, spine, ribs, and the four sets of the limbs. By looking at the shape of the bones, shape, and structure the anthropologist will know if the bone is for a human. By doing so, the information could explain whether the bones are for one individual all they are for other animals, male or female. The teeth of the remains look wet due to the enamel hypoplastic disease. The enamel of the teeth is also
