Could a "thinking cap" help us learn?






Vanderbilt researchers use cap to electrically stimulate learning skills
Many K-12 teachers suggest to students that they should “put your thinking caps on,” and one day, students might just do that for real. Vanderbilt University psychologist Geoffrey Woodman says that’s because scientists are being equipped with more and more tools they can use to better understand the brain, and now, they can even eavesdrop on individual neurons.

Initial support from the National Science Foundation (NSF) allowed Woodman and his team at the Vanderbilt University Visual Cognitive Neuroscience Laboratory to study memory and perception. Then, the researchers tested their theory that electrical stimulation of the medial frontal cortex can boost learning and improve decision-making.

The research in this episode was funded by NSF award #0957072, Interactions Between Visual Working Memory Representations and Mechanisms of Perceptual Selection.

new techniques reveal the brain's complexity

NSF’s brain research support aims to enable scientific understanding of the full complexity of the brain, in action and in context, through targeted, cross-disciplinary investments in research, technology and workforce development. Understanding the Brain activities promise innovative and integrated solutions to challenges in our ability to predict how collective interactions between brain function and our physical and social environment enable complex behavior.

Ed Boyden, a professor at the Massachusetts Institute of Technology, knew he wanted to apply his training in electrical engineering to understanding the brain. A successful experiment with blue light and a dish of cultured brains cells in August 2004 ultimately led to the development of a revolutionary new research technique known as optogenetics. Optogenetics enables scientists to use light to precisely control the activity of neurons in the brain. Read more in thisdiscovery.
