1. How is brain development related to adolescent impulsivity? During adolescent development, the brain processes information differently compared to the way that an adult brain processes information. Since a neural structure is not yet in place due to the prefrontal and frontal cortex still being in the process of development, the adolescent brain will rely on the amygdala (i.e. the section of the brain responsible for decision making and reactions) to process their emotions. This is different…

Esther Faveur Psych 309-01 Professor Kaplan 9/26/13 Effects of BPA on Memory Bisphenol-A is a chemical that is found in food and beverage containers (Nienstedt, 2013). Many studies suggest that exposure to Bisphenol-A (BPA) during early development may cause memory inadequacy later in life. A study conducted by Luine, Eilam-Stock, Serrano & Frankfurt (2011), sought to investigate the effects of BPA on spatial and visual memory in adult rats. In their paper, they describe the influence of…

brain’s pleasure center then needs more stimulation to achieve the same amount of effect. What was once just a pleasurable pastime has now become a necessity to the individual. In this book by David Linden, he discusses pleasure from a biological perspective. He focuses on the brain and how it is affected by pleasure, be it from substances or by behaviors. He discusses the concept of association and its role in the development of addictions. He also talks about how addictions are partly nature and nurture…

impairment of the prefrontal cortex; the location in the brain responsible for making appropriate decisions and managing social behaviours, among other functions (Social, emotional, and executive functioning, 2012). Additionally, researchers noted that the sucrose exposed rats performed at a lower level of functioning than the control group in “object-in-place” tasks, where recognition memory was required (2015). This potentially indicates a decline in functioning of the prefrontal cortex, as well as the…

mind that you may not experience all of these effects and that not all of them are well-documented in the scientific community. • Accelerated brain aging Cocaine may cause the brain to age at a quicker rate than average. This is in part due to significant losses in the amount of grey matter in important areas of the brain, but also due to functional deficits in various brain regions. Cocaine usage over the long-term can yield significant detrimental effects on the brain, increasing speed of neurodegeneration…

children are determined to be victims of abuse or neglect annually (U.S. Department of Health and Human Services, 2010). Exposure to traumatic events in childhood has significant effects on cognitive development (Pechtel & Pizzagalli, 2011; Veltman & Browne, 2001). Current research examining brain development suggests the type, magnitude and persistence of effects depend on when during development trauma exposure occurs (Andersen, et al., 2008; Pechtel & Pizzagalli). The brain undergoes rapid growth…

in a skillet. The message was mostly for young people to warn them of the effects of illicit drugs on the brain. This was a fairly accurate demonstration of the harmful effects that drugs, including alcohol, nicotine and cocaine can have on a developing brain. Adolescence is a time of important brain development, specifically with regard to the prefrontal cortex. It is during this period of human development that most teenagers’ thinking progresses from concrete operational thinking…

A strong emotional stimulus triggers coherent details of a memory, known as flashbulb memory. There are two pathways in the brain that develop a flashbulb memory; emotional intensity and the predicted frequency of overt and covert rehearsal. Rehearsal is a direct determinant of the lucid memory. The amount of exposure to enhance the accuracy of the event is vital to recalling a story. Personal experience rather than sematic knowledge makes the memory error-prone. It is first person heard, experienced…

Nina Lamberti Mr.Hahn Biology Honors 10/31/12 Review of Literature The purpose of this experiment is to determine if gender bias has an effect on memory. The independent variable is gender Bias, which is the different treatment of someone due to his or her gender. The dependent variable is in the study is Memory. Memory is the brains capacity to hold information. Based on the research I found on the internet there seems to be a connection between gender bias and memory variation. With this…

Hector Ferreira Eleanor Lurye Psychobiology G250 29 May 2015 The Darkness Behind Schizophrenia Schizophrenia is slowly evolving more and more into the common world. Schizophrenia is said to be a stern, incessant disabling brain disease. It is alleged that roughly 1 percent of the country’s population is to develop schizophrenia in the duration of their lifetime. That’s close to 2 million American’s suffering each year, and it is conjectured to grow in numbers. While schizophrenia determinates…
