What role does the brain play in the study of psychology and how can it affect behavior?Don't miss The body's two intenal The Organization of the Nervous System systems, themnbune nervous system and the endocrine system, both use chemical messengers to communicate with targets throughout the body. The Nervous System The nervous system consists of all the nerve cells in the body. Its two major divisions are the central nervous system and the peripheral nervous system. The central nervous system is comprised of the brain and the spinal cord and will be discussed in further detail in Topic 3 The diagram to the right Mustrates the organization of the nervous system. The peripheral nervous system connects the central nervous system to the limbs and organs through nerves. It is divided into the somatic nervous system and the autonomic nervous system The somatic nervous system is associated with the body's voluntary control of movements. It acts as the brain's communication link to the outside world The autonomic nervous system is associated with the body's involuntary movements and is divided into two parts: the sympathetic nervous system and the parasympathetic nervous system Sxmpatbetic Nervous Systemys Parasympathetic Nenous System Neurons are responsive cells that process and transmit information through electrochemical signaling Neurons.and How They Work Neurotransmitters are chemical messengers that relay n messages across the synapse. This table lists the seven types of neurotransmiters and descibes: their normal function, what problems result as an imbalance of that particular neurotransmitter, and the substances that affect each particular neurotransmitter eural The Endocrine System The endocrine system consists of glands that secrete hormones into the blood. These hormones, in turn, communicate with the rest of the body to stimulate change. The diagram to the right lustrates the glands that comprise the endocrine system. The Endocrine Syatem Not only do hormones carry messages that influence body functions, but their messages also influence behaviors and emotions. Some behavior patterns include parental care, territorial behavior, and circadian rhythms (behavior patterns that always occur at the same time each day). Through a network of nerves, called the nervous system, and hormones secreted into the blood by the glands of the endocrine system, the body communicates with itself to influence body functions, behaviors, and emotions
Explanation / Answer
Role the brain play in the study of psychology:
-Psychology is the scientific study of behavior and mental processes.
-Neuroscience shows that activity in the brain is intimately intertwined with behavior and mental processes.
- Dualism is the idea that the mind and the body are two separate entities; stands in opposition to the idea that consciousness can arise from purely physical processes.. Since the body is a physical entity and the mind is not, for many centuries philosophers (and later, psychologists) usually operated under the assumption that the body and the mind were of different kinds of substance. Rene Descartes famously theorized that the mind and body were separate, since he could doubt that he had a body because he might be dreaming, but he could not doubt that he had a mind since something was doing the doubting. Thus, the central claim of what is called Cartesian dualism is that the mind and the body are two separate substances that interact.
- Studying damaged brains is one of the most useful ways to increase our understanding of the links between the brain and behavior. A lesion is a general term for any abnormality in tissue, usually caused by disease or trauma. Lesions are important to the study of brain and behavior because if a psychologist sees a person with a partially damaged brain and then sees changes in that person’s behavior, those behavioral changes can often be attributed to the brain damage. For example, damage to a part of the brain called Broca’s area causes patients to lose the ability to speak; knowing this, we can infer that that part of the brain is in some way related to language production. This gives us more information about neuroanatomy and also about the influence the brain has on behavior.
How can it effect behaviour:
-Science has made huge strides in understanding the human brain and how it functions.
-For example, we know that the frontal lobes are the center of rational thinking and of self control.
-It is also understood that neurotransmitters, or brain chemicals, are responsible for our moods and of the general state that we are in.
-It is also known that severe mental illnesses, such as Schizophrenia and Bipolar Disorder, are diseases of the brain.
-Lesions or damage to the frontal lobes and to other parts of the brain can and affect impulses and impulsive behaviors.
