The cerebellum is most recognised for its role in movement control. The cerebellum is also vital in recalling emotional memories, according to researchers at the University of Basel.The findings were published in the journal PNAS.Both positive and negative emotional experiences are stored particularly well in memory. This phenomenon is important to our survival, since we need to remember dangerous situations in order to avoid them in the future. Previous studies have shown that a brain structure called the amygdala, which is important in the processing of emotions, plays a central role in this phenomenon. Emotions activate the amygdala, which in turn facilitates the storage of information in various areas of the cerebrum.The current research, led by Professor Dominique de Quervain and Professor Andreas Papassotiropoulos at the University of Basel, investigates the role of the cerebellum in storing emotional experiences. In a large-scale study, the researchers showed 1,418 participants emotional and neutral images and recorded the subjects' brain activity using magnetic resonance imaging.In a memory test conducted later, the positive and negative images were remembered by the participants much better than the neutral images. The improved storage of emotional images was linked with an increase in brain activity in the areas of the cerebrum already known to play a part. However, the team also identified increased activity in the cerebellum.The cerebellum in communication with the cerebrumThe researchers were also able to demonstrate that the cerebellum shows stronger communication with various areas of the cerebrum during the process of enhanced storage of the emotional images. It receives information from the cingulate gyrus - a region of the brain that is important in the perception and evaluation of feelings. Furthermore, the cerebellum sends out signals to various regions of the brain, including the amygdala and hippocampus. The latter plays a central role in memory storage."These results indicate that the cerebellum is an integral component of a network that is responsible for the improved storage of emotional information," says de Quervain. Although an improved memory for emotional events is a crucial mechanism for survival, it does have its downsides: in the case of very negative experiences, it can lead to recurring anxiety. This means that the findings, which have now been released, may also be relevant in understanding psychiatric conditions such as post-traumatic stress disorder.Basel research on emotions and memoryThe current study forms part of a large-scale research project conducted by the Research Platform Molecular and Cognitive Neurosciences (MCN) at the University of Basel and the University Psychiatric Clinics (UPK) Basel. The aim of this project is to gain a better understanding of emotional and cognitive processes and to transfer results from basic research to clinical projects.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
