In 2012, four researchers at MIT researched the cerebellum’s role in predictions dealing with sounds produced by oneself, as well as sounds produced by others. The initial question in this experiment was whether or not “auditory stimuli are anticipated as a consequence of a motor act” (Knolle, Schröger, Baess, Kotz, 2012). In short, a total of twenty-two patients participated; eleven had a lesion located in the cerebellum, and eleven were healthy controls. Each participant underwent two experimental situations and one control. The conditions were auditory-motor, auditory-only, and motor-only, known as AMC, AOC, and MOC respectively. During the AMC, participants were instructed to tap their finger approximately every 2.4 seconds. The tap generated an immediate playback of a tone. In the auditory-only condition, the tone was played every 2.4 seconds, with no finger taps required. During the MOC, participants tapped their fingers every 2.4 seconds (self-directed). The experiment outcome found that the healthy controls “show the expected N100 suppression” generated by the finger taps (Knolle, et al, 2012). Conversely, participants with cerebellar lesions did not show the same expected brain activity. These participants struggled in predicting the tone playback during the auditory-motor-condition. Therefore, one of the cerebellum’s key roles in brain function is developing predictions using a forward model. A great deal of research finds that a key cerebellar role is motor control and planning; however, this experiment also found that the cerebellum plays a role in “sensory processing and cognition” (Knolle, et al, 2012).

The cerebellum is one of the best-known brain structures; this sector of the brain is approximately the size of...

.... For example, sexual hormones are secreted when the hypothalamus receives signals from the cerebral cortex; the hypothalamus plays a significant role not only in bodily homeostasis, but in brain function.

The Function of the Cerebellum Essay

- Previous studies that have researched the functions of the cerebellum have focused on investigating individuals that have damage to their cerebellum, such as was the case with the Phineas Gage’s frontal lobe study that proved that the frontal lobe served an important role in personality and behavior. Recent studies have had the advantage of new technologies that could significantly aid in identifying whether or not the cerebellum plays a role in specific functions, these include functional imaging techniques such as fMRI and PET imaging, and these recent technological advances have paved the way for new studies that focus on brain region activation....   [tags: anatomy, cerebellum]

The Role of the Amygdala in Human Functioning Essay

- History The term ‘amygdala’ was first used by Burdach (1819) and referred to a set of nuclei in the brain (Aggleton & Saunders, 2000). In 1939, researchers Klüver & Bucy inflicted bilateral lesions of the inferior temporal lobe of monkeys in a laboratory in an attempt to reduce aggression. These lesions affected the cortical areas, amygdala, and the hippocampus. Later this became known as Klüver-Bucy syndrome, and consisted of symptoms such as psychic blindness, hypermetamorphsis, oral tendencies, and changes in emotional and sexual behaviors....   [tags: Physiology, Neurology]

Amygdala and Depression Essay

- Adolescent Depression and the Amygdala Introduction and Method Adolescence is one of the most concerning times when it comes to depression. One study completed by Tony T. Yang and colleagues (2010) wanted to gain more knowledge on this subject. The goal of the Yang et al study was to compare the Amygdala in depressed adolescents to their healthy counterparts in order to grasp a better understanding of adolescent depression. The study focused on observing to see if there was any correlation between neural activity in the bilateral amygdala and adolescent depression....   [tags: Mental Health ]

Behavioral Management and the Hawthorne Effect Essay

- Behavioral management is “the study of how managers should behave to motivate employees, encourage them to perform at high levels and to be committed to the achievement of organizational goals” (Waddell et al. 2007, p. 52). A number of intellectuals explored possible theories that would explain the basis and effect of behaviours of both the management and staff. Some theorists whose ideas are still prominent today include Fredrick Taylor, Mary Follett, Douglas McGregor and Elton Mayo et al. This piece, however, focuses on the ‘Hawthorne effect,’ conducted by Elton Mayo alongside associates F.J....   [tags: Behavioral management, Business Management]

Essay on Cognitive Behavioral Therapy ( Cbt )

- ... So if the therapist did choose to use the diagnostic interview for the assessment for the treatment process, this is when they would identify the phobia and define the specific behaviors and thought processes dictating that phobia which will guide the course of treatment. Once the problem is addressed the therapist can create a plan for treatment: how the problems will be specifically addressed and how maladaptive behaviors will be relearned or redirected. The therapist will then implement this plan, and finally terminate when appropriate (Ledley & Heimberg, Pg 74)....   [tags: Cognitive behavioral therapy, Psychology]

Animals are Valuable in Behavioral Research Essay

- From the dawn of time, when the first human killed an animal for food, or drove it from a fruit patch so that he could eat instead, there has been competition with animals for basic resources. Likewise, over the ages, humans have contemplated their relationship with animals. Ancestral societies worshipped the animals they used recognizing that the lives they took fueled their own lives. Further introspection on humanity's place in the world resulted in the development of codes of morality and ethics and subsequently the first modern religions....   [tags: Behavioral Research Essays]

Studying Genetically Altered Mice in Behavioral Genetics Essay

- The field of behavior genetics is rapidly expanding. The practice of altering genes in mice and observing the effects is very common. Because of this it would be appropriate to adopt specific tests which will demonstrate the behavioral phenotype of the organism. In testing for the effects of genetic alteration it must first be ascertained that all of the necessary genotypes are represented. These include homozygous and heterozygous mice and wild type mice with no genetic alterations as controls....   [tags: Behavioral Genetics]
