pressure). Why we need sleep: For physical restoration, adaptation, growth, and memory. What it does for us: Sleep rests the body and mind. The effects of chronic sleep deprivation: Have trouble paying attention to tasks and solving problems, decreases brain activity. The 5 stages of sleep: Stage 1: drowsy sleep; myoclanic jerk; (theta waves) Stage 2: Muscle activity decreases Stage 3 & 4: delta waves; deep sleep Stage 5: (REM) dreaming occurs (Rapid Eye Movement) Major sleep disorders: insomnia-

Biopyschologists believe that every mental event involves a brain event. Many people have experienced severe injuries and trauma to their brains in their lives. However after undergoing exercises, surgery or therapy it is able to help them repair their brains as well as change their minds and literally change their brains. The process whereby their brains change in response to experience is called neuroplasticity. There are various forms of neuroplasticity such as homologous area adaptation, map

hormones responsible for different behaviors either directly or indirectly. “Gender identity is how we feel about and express our gender and gender roles — clothing, behavior, and personal appearance. It is a feeling that we have as early as age two or three” ("Gender And Gender Identity", 2001). While there is much to say about the brain and its relationship to personal gender identity it is also very evident that the interaction between hormones and behavior is a deciding factor as well. Biological

reproducible conditions. Second, emotions such as fear behaviors, involve relatively primitive circuits that are conserved throughout mammalian evolution (LeDoux, 2000), therefore allowing animal models systems different from humans to be a well suitable candidate to reveal brain circuits underlying specific behavioral responses and mechanisms that ultimately regulates emotional learning and memory. In particular, the experimental acquisition of fear responses serves as a powerful model for studying associative

An Examination of the Concept of Learning Martin Eckelberry Psych/550 Psychology of Learning 11/24/2014 Thomas Pourchot An Examination of the Concept of Learning Learning, simply stated, is the acquisition of knowledge (Terry, 2009). The concept of learning is not as simple to explain. When examining the concept of learning it is important to address the origins of the study of learning, the difference between learning and performance, and understanding the four conceptual approaches to

control of your mind shifts between myriad competing and conflicting intelligences. These intelligences were assembled over millions of years to become the present triune human brain. At the lowest level, a reptilian brain controls primitive functions like breathing, hunger and heartbeat. At the next level, a mammalian brain controls the system through love and despair, compassion and shame. At the highest level exists

1) In regard to the issues of the extent of abnormal behavior, explain the following terms: (Ch1.Pg12) a. Epidemiology: the study of the distribution of diseases, disorders, or health-related behaviors in a given population. b. Prevalence: refers to the number of active cases in a population during any given period of time. c. Lifetime Prevalence: an estimate of the number of people who have had a particular disorder at any time in their lives (even if they are now recovered). 2) What are some

in the brain is aimed at being able to try and rebuild connections between the nerve cells or neurons (Campbell, 2009). The rebuilding between nerve cells or neurons can provide a high chance in making it possible for a function that has been previously managed by a damaged area to be taken over by another undamaged are. I came across a very interesting video that was broadcasted on ABC, hosted by Leigh Sales. The video features Psychiatrist Norman Doidge, who is also the author of ‘The brain that

anesthetized. Following standard surgical procedures, an incision will be made in the scalp and two holes drilled in the animal's skull. Electrodes will be lowered into the brain to create lesions on each side. The animals will then be allowed to recover. Several weeks later, the effects of destroying this part of the animal's brain will be tested in a shuttle avoidance task in which animals will learn when to cross over an electrified grid. The instructor admits the procedure is a common demonstration
