![]() Its main functions are to regulate voluntary movements, including eye movements, help with balance as well as posture. The basal ganglia are a group of structures, situated at the base of the forebrain and top of the midbrain. The following structures are not structures of the limbic system, but form complex networks and interact closely with the limbic system, aiding in many functions. There are also links of amygdala differences in those with Autism, depression, posttraumatic stress disorder, and bipolar disorder. Therefore, the amygdala is also linked with the fight-or-flight response, as stimulating activity in the amygdala can influence the body’s automatic fear response.ĭamage to the amygdala can result in more aggression, irritability, loss of control of emotions, and deficits in recognising emotions, especially recognising fear. ‘Fear learning’ is also an element of the amygdala.įearful memories can be formed after only a few repetitions, which can result in avoidance of certain fearful stimuli. It has a role in how memorable memories can be – memories that have strong emotional components tend to stick, rather than those with little emotional content. The amygdala interacts with the hippocampus by attaching emotional content to memories. ![]() This area is also key for the formation of new memories. The main function of the amygdala is in emotional responses, including feelings of happiness, fear, anger, and anxiety. The amygdala is an almond-shaped structure, located right next to the hippocampus. ![]() The limbic system is thought to be an important element in the body’s response to stress, being highly connected to the endocrine and autonomic nervous systems. These structures are known to be involved in the processing and regulating of emotions, the formation and storage of memories, sexual arousal, and learning. Psychologists now recognize that the limbic system serves a lot more functions than previously believed. The limbic system was originally called the rhinencephalon (meaning ‘smell brain’) because it was thought to be primarily involved with the sense of smell. The limbic system is located within the cerebrum of the brain, immediately below the temporal lobes, and buried under the cerebral cortex (the cortex is the outermost part of the brain). The limbic system is a collection of structures involved in processing emotion and memory, including the hippocampus, the amygdala, and the hypothalamus.
