New paper in The Journal of Neuroscience
Isabella, Darcy, and Jan have new work at The Journal of Neuroscience this week: http://www.jneurosci.org/content/early/2018/01/05/JNEUROSCI.3091-17.2017
From the significance statement:
The ability to rapidly stop ongoing actions allows humans to flexibly and rapidly adapt their behavior. Action-stopping is important in daily life (e.g., stopping to cross the street when a car approaches) and is severely impaired in many neuropsychiatric disorders. Therefore, finding ways to improve action stopping could aid adaptive behaviors in health and disease. Our current study shows that presenting unexpected sounds in stopping-situations facilitates successful stopping. This improvement is specifically due to a surprise-related increase in a neural mechanism for motor inhibition, which rapidly suppresses the excitability of the motor system after unexpected events. These findings suggest a tight interaction between the neural systems for surprise processing and motor inhibition, and yield a promising avenue for future research.
Open data for this study is available as well (link in the article).
