Hormones are transported through the blood stream to various organs and tissues. The male hormone is testosterone and the female hormone is oestrogen. Too much or too little of a particular hormone can lead to psychological problems for example too much dopamine can cause schizophrenia 1.b) Describe Selyes GAS Theory According to the biological approach hormones are responsible for regulating behaviours. Selyes General Adaptation syndrome (GAS) theory focuses on how the body respond to stress. Selyes research on rats led him to conclude that when exposed to stressful situations we display a universal response to all stressors regardless.
This is how scientist have been able to come up with medication to treat mental illnesses like depression, anxiety, depression, bipolar disorder, and schizophrenia. They have proven that there is a connection with genes and chemical changes in the brain that causes theses illnesses in the mind but with the right treatment, it can adjust the changes and chases the illness away. What is the historical development of biological psychology? While psychology is very broad, it is important to know the history of biological psychology because some of the past experiences have shaped into this school of thought to what it is today by providing us with a better
This is important statement because it proves that gender identity and sexual orientation is not purely choice, but driven by biological forces. Because hormones play such a diverse role in bodily functions, I will break down hormones into categories to provide clarification. Hormones are chemicals that come from the endocrine gland and are released into the circulatory system (Pinel, 2009). Hormones affect other endocrine glands or various parts in the nervous system. There are three types of hormones: amino acids, peptides and proteins, and steroids (Pinel, 2009).
The first treatment in biological therapies is chemotherapy; this is the use of drugs to treat a mental illness. Under chemotherapy there are 3 main types of drugs; Antipsychotic, antidepressants and anxiolytic. Anti psychotic drugs are generally used for more severe mental health problems such as schizophrenia. They work by balancing chemicals in the brain such as dopamine as this is linked with there hallucinations. Antidepressants on the other hand by balancing neurotransmitters such as serotonin and epinephrine witch can cause depression if not sufficiently balanced.
Brain scans can be used to help diagnose some disorders. Furthermore, the genes we are born with, from our parents, provide the blueprint for our bodies and brains. A slight abnormality in our genes can affect the functioning of our brains. Also to operate properly the brain relies on hundreds of chemicals to operate in the correct balance, these chemicals are used to send messages around the brain. Therefore if there are chemical imbalances abnormality may occur, for example low levels of serotonin are linked to depression and schizophrenia is linked with high levels of dopamine.
Oligodendrocyte produces a white substance call myelin that insulates the axons (Gross, 2009); destruction to the myelin consequently produces diseases called myelin disorders which results in demyelination (Thibodeau & Patton, 2005). Initially, this essay will be addressing the question on myelin and the aetiology of demyelination, followed by various neuropathological research carried out to determine the impact of multiple sclerosis (MS) on the brain and its relationship to cognition and depression. Myelin serves a fundamental purpose in the CNS due to the nature and mechanism of its necessary function. It is characterised as a white substance made of lipid fat and proteins, produced by the oligodendrocytes, a glia cell (Thibodeau & Patton, 2005). Its primary functions are producing, maintaining and repairing neurons along the long extension of the axons (Rodriquez, 2003).
Define and outline the biological approach to aggression The biological level of analysis focuses on the many physiological factors that play a role in behaviour – brain processes, neurotransmitters, hormones and genes. Biological researchers therefore take a reductionist approach to the study of behaviour – breaking complex human behaviour into its smallest part eg. Focusing on the role of a gene, a neurotransmitter, or a localized part of the brain. This can be seen in the case studies of Phineas Gage and David (Bruce / Brenda Reimer). Phineas Gage was a railroad worker who suffered a personality change after an iron rod shot through his brain.
Is a person exhibiting maladaptive behavior due to something genetic; or is it something neurological; something gone awry in the brain cells? The Biological Perspective considers and strives to answer these and similar questions Psycho-dynamic Perspective holds that our thoughts and emotions provoke our mood and influence our behavior. Psychoanalysis is the method of approach taken by reach people who are deeply disturbed. This method challenges the patient to release repressed emotions and to search for the meaning behind his/her Theories 3 way of thinking. The environment in which we find ourselves plays a very big part in how we
Biomedical therapies- Treatments for psychological disorders that alter brain functioning with chemical or physical interventions such as drug therapy, surgery, or electroconvulsive therapy. 3. Biopsychosocial model- A model of health and illness that suggests that links among the nervous system, the immune system, behavioral styles, cognitive processing, and environmental factors can put people at risk for illness. 4. Clinical ecology- A field of psychology that relates disorders such as anxiety and depression to environmental irritants and sources of trauma.
In this report I’m going to be telling you about how neurotransmitters affect our lives and the people around us. I’m also going to be explaining what these things called neurotransmitters are, the different type of neurotransmitters we have and what they do. Also what would happen to our body if we have too many or too little amounts of neurotransmitters and how illegal and legal drugs affect the functioning of neurotransmitters? Neurotransmitters are a chemical substance which is released at the end of a nerve strand by the entrance of a nerve impulse and by spreading across the synapse. It effects the transfer of the impulse to another nerve strand, a muscle strand, or another structure.
