About the Author

Jaap Murre
Jaap Murre

I am Professor of Theoretical Neuropsychology at the University of Amsterdam studying memory and the brain. I often use neural network models to help understand how the brain works. I like programming and have created several systems for simulation and experimentation. Over the past years we have also conducted many experiments on learning and forgetting, both in the lab and via the Internet.
