Shaina Hudgel PY140 Abnormal Psychology Exam 1 Part B Essay 1: Scientists study the brain to try to understand its role in mental health issues. Identify the major brain structures involved and describe what experts believe to be the role of each. There are three major brain structures involved in scientists trying to understand the brain’s role in mental health issues. Neuroanatomists, the scientists that study the anatomy and stereotyped organization of nervous systems, have divided the brain into the hindbrain, midbrain and forebrain. The hindbrain, which includes the medulla, pons, and cerebellum, regulates basic bodily functions. For example, the hindbrain will regulate our need to urinate, breath, and sleep, as well as regulating heartbeats. Scientists believe there are very few forms of abnormal behavior linked with disturbances in this part of the brain. The midbrain, which includes the tectum and tegmentum, is involved in the control of some motor activities such as those relating to fighting and sex. The reticular activating system, which regulates sleeping and waking, is mainly located in the midbrain. Scientists have found that damage to areas of the midbrain can cause extreme disturbances in men and women. For instance, extreme abnormalities in sexual behavior, aggressiveness, and sleep are common though usually more typical from specific brain traumas or tumors. The forebrain, which includes the cerebrum, thalamus and hypothalamus, is actually the site of most sensory, emotional, and cognitive processes. The limbic system (which includes the thalamus and hypothalamus among other components) links the forebrain to both the hindbrain and the midbrain. Scientists believe that major damage to the forebrain and limbic system can cause extreme abnormalities in the retrieval and integration of sensory information, as well as in the autonomic nervous system. Currently, only the most severe mental disorders have been able to be clearly linked to abnormalities in neuroanatomy. Neuroscientists have made major breakthroughs in creating new, more interesting methods to observe the brain and make a diagnosis based on those findings. They will also, hopefully, continue to perfect these methods as well as create newer, and better methods in the future.

Shaina Hudgel PY140 Abnormal Psychology Exam 1 Part B Essay 2: Behavioral genetics focuses on the way in which genes pass along traits or conditions. Explain the basic process of applying behavioral genetics in working with a client with a condition that could be inherited. Behavior genetics traditionally studies broad genetic influences on normal and abnormal behavior, focusing on whether genes are more or less important in development. Applying behavioral genetics in working with a client with a condition that could be inherited can be relatively simple or extremely difficult. It really all depends on the client and what they know about themselves and their family.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
