Action Selection Under Time-Pressure

Vertical Tabs

Visualization of the connectivity in the human brain based on diffusion magnetic resonance imaging. Structural connections are critical for information sharing throughout the brain and are vulnerable to injury in traumatic brain injury.

Vertical Tabs

Effective tactical operations require a soldier to make complex decisions while operating a broad range of systems under extreme environments. This work focuses on defining patterns of brain activity as well as responses of the autonomic nervous system that are indicative of potential performance failures. Experiments are performed with healthy subjects as they make decisions under time pressure combined with different sources of stress such as fatigue, distraction, large incentives or losses and noisy environments. The goal is to develop new approaches for training and to identify brain or peripheral nervous system monitoring tools.
