How a racing heart may alter decision-making brain circuits

In an effort to understand how the internal state of the body influences the brain's decision-making processes, scientists analyzed the data from a previous study pre-clinical study. They found that two of the brain's decision-making centers contain neurons that may exclusively monitor the body's internal dynamics. Furthermore, a heightened state of arousal appeared to rewire one of the centers by turning some decision-making neurons into internal state monitors.
