Title : Dr Jekyll and Mr. Hyde revealed: Tales from the default mode network
Abstract:
The discovery of the default mode network (DMN) over 20 years ago has provided a new perspective in understanding brain function, the nature of consciousness, and behaviour. Frequently overlapping and including nuclei of the limbic system, the DMN is a distributed and integrated network of brain areas originally shown to be suppressed when people focus on external stimuli. The DMN has been shown to be most active during periods of wakeful rest, mind wandering and daydreaming allowing us to reflect on recent and distant past experiences, emotions and interactions, and adjust our conscious interpretation of the past and envision the future.
Recently, a greater understanding of how the DMN significantly affects cognition and behaviour in present time is emerging. This presentation builds on the larger known neuroplastic changes in the limbic system and their contribution to increasingly detrimental decision making through DMN activity changes and influences, as addiction progresses. Furthermore, in exploring the neuroscience of recovery, positive neuroplastic changes reflected in DMN activity correspond to improved mood, worldview and healthy behaviours.
Through consideration of ‘hot’ and ‘cold’ decision making processes, mechanisms and bias in internal/external switching mechanisms, the tale of the functional alcoholic is revealed. Through this presentation, the audience will gain an understanding of the mechanisms behind highly talented persons (Dr Jekyll) consistently sabotaging others (Mr. Hyde) and eventually themselves over their life course. Most importantly, understanding the DMN and measures to elevate base functioning gives key insights into highly effective treatment for addiction.
