Change Detection Research Interests
Current research in my lab centers on the brain mechanisms underlying perceptual and motor skill learning. Our past experience fundamentally influences how we perceive the world around us and how we behave in it. Similarly, the neural mechanisms of perceptual analysis and motor control are the results of extensive learning. However, little is known about how such mechanisms are sculptured by experience. Our studies focus on how working memory representation of visual objects becomes more efficient as we become familiar with a particular class of visual objects (e.g., English alphabets). Specifically, we are evaluating the hypothesis that experience changes how information about visual objects is represented in some cortical areas, such as the prefrontal cortex. This work is performed in monkeys trained for various working memory tasks, such as the change-detection task.
