Understanding how brains make perceptual decisions is critical for gaining insight into complex cognition. Decisions reflect a commitment to one out of a number of alternatives and differ from simple sensorimotor reflexes in that they require an animal to integrate multiple sources of information before committing to action. Because these perceptual decisions invite animals to use sensory signals on this flexible timescale, they offer a tractable entry point into more complex cognitive processes defined by flexibility, such as abstract thinking, reasoning and problem solving.
In my laboratory, we investigate the neural circuits underlying decision-making. We use carefully designed paradigms that encourage experimental subjects to deliberate over incoming sensory evidence before making a decision. We develop behavioral paradigms to study decision-making, and measure and manipulate neurons during those decisions. Our long term goal is to understand how the brain can make decisions that integrate inputs from our multiple senses, stored memories and innate impulses.
