Motivated behavior

Throughout the years of historical research in neurology, there have been major advances made in the understanding of motivated behavior. Motivated behavior refers to purposeful actions taken by an individual when attempting to fulfill a goal. Studies in neurology that illustrate motivated behavior typically involve the use of anatomical and physiological investigations of the brain. Through neurological testing, researchers are able to gain a better understanding of how specific areas of the brain are involved in influencing behavior. One example of a neurology study looking at motivated behavior was conducted at the University of Geneva. This study used PET scans to observe brain function while individuals engaged in goal-oriented tasks. Researchers found that there was increased neuronal activity and excitement in the striatum area, indicating that it is responsible for developing intention to accomplish a task-related goal. This finding provides evidence that the striatum is a key player in motivated behavior. Other studies have investigated the role of neurotransmitters and hormones in motivated behavior. Neurotransmitters and hormones are two chemical messengers that help to regulate various functions of the body. For example, a study conducted at Johns Hopkins University found that increased levels of dopamine, the “reward and pleasure” neurotransmitter, were linked to heightened feelings of motivation. Additionally, research has looked into the role of hormones, such as cortisol, in influencing motivated behavior. Cortisol, the hormone released during times of stress, was found to depress motivated behavior, suggesting that it reduces enthusiasm during difficult or challenging tasks. The research conducted in neurology studies concerning motivated behavior has provided valuable insight into the biological factors that play a role in our goals and intentions. Identifying the specific areas of the brain and chemicals involved in this process may provide opportunities for therapies to improve the overall effectiveness of motivated behavior.
