Brain Structures Essay
What general brain structures are involved in motivation and emotion? What role do these structures play in motivation and emotion?            In the field of psychological and anatomical biology, the behavioral characteristics of the human psychology are mainly related to the activities and processes in the different regions and structure of the human brain. Physiologically, the brain controls the different behavior, mood, and other personal characteristics of the person through the functions and hormonal changes in the involved brain regions. Included in these psychological characteristics are motivation and emotion wherein the development and formulation of these behavioral patterns are rooted n the psychobiological structure of the brain.            The aspect of motivation is mainly guided by two dominant concepts namely the reward system (appetitive motivation) and the fight or plea system (aversive motivation). Both of these psychological systems are guided by the hormonal changes and activities in the involved brain region. In particular, motivation in the human behavior is guided by the pleasure and reward mechanism of the brain wherein the human reacts towards the achievement of the benefit of his or her action. In this perspective, the role of the subcortical structure composed of the limbic system, thalamus, hypothalamus, basal ganglia, and midbrain becomes significant as the development and regulation of motivation in the human behavior. These structures produce motivation through the manipulation of hormonal secretion such as dopamine and other pleasure sensors thus, creating the reward system and interest factor of the individual behavioral system.            Emotion on the other hand, is scientifically related to the limbic system, the basal ganglia, thalamus, hypothalamus, and likewise the subcortical system in the human brain as the brain region controlling the development and formulation of emotion in the human behavior. In the psychobiological perspective, emotion becomes the result of the altercation in the physiological behavior of the human body as the result of the hormonal secretion controlled by the human brain. In this concept, the involved region of the brain intercepts the stimulation from the sensory regions and controls the physiological system of the human body such as heartbeat, breathing rate, sweat secretion, and others creating the general emotional reaction of the human body.            In general, the physiological reaction of the human body creating the behavioral characteristic of the person becomes the product of the control of the human brain. The behavioral characteristic of the human person such as motivation and emotion are regulated and are controlled in the brain region.  Bibliography Westen, Drew (1998).
