When we think about the mind and body, psychologists and historians have provided theories that correlate these two ideas and their functions that make us human. Without the mind our body cannot achieve its purposes and without the body our mind remains useless. These two branches influence each other and can set off different chains of reactions in our mental world [mind] and our physical world [body]. There are relationships between what we experience (such as thoughts and feelings) and what our biological processes are (such as activity in the nervous system) (Morris, 2005). The connection between mind and body is that they are not separate entities, rather they are closely connected and interact with each other to function properly. The five fundamental issues with which psychologists have associated mind-body are biological psychology (dealing with the nervous system and its function), sensation/perception, consciousness, motivation/emotion, and clinical psychology (which has to do with disorders/therapy). Problems are an emerging principle that affects how the mind-body interacts. In biological psychology we talk about the scientific study of mental processes and behavior, coinciding with the performance of some cognitive activities. In sensation and perception, sensation refers to the process of perceiving our environment through touch, taste, sight, sound, and smell. This information is sent to our brain in raw form where perception comes into play. Perception is how we interpret these sensations and therefore make sense of everything around us.? In terms of consciousness, we associate it with the state of being awake and aware of what is happening around you. This is also a quality of the mind that attributes to our attention. When dealing with motivation and emotion, the psychologist defined motivation as the initiation, direction, intensity and persistence of behavior, which has a temporal and dynamic state unrelated to one's personality or behavior. Emotion is what is described as “an intense mental state that emerges autonomously in the nervous system rather than through conscious effort.” It can evoke a negative or positive response that will be related to how we behave. Clinical psychology deals with the research and treatment of psychological distress, dysfunction, or disorder. Psychologists who focus in this field treat more serious disorders, such as phobias, bipolar disorder, and schizophrenia. (Rishel, 2000) The nervous system is the “information collector, storage center, and control system” of our body. Collects information about external conditions in relation to the internal state of the body, to analyze this information and to initiate appropriate responses to satisfy certain needs (Maintaining homeostasis).
