In the above movie I used topo software (by Hitachi) to visualize the blood flow changes in the brain. The data was collected by Hitachi ETG 4000 and the subject was myself. I was doing a finger tapping task. The probe position was measure by 3D digitizer. You can see that during finger tapping (right hand) the blood flow in the left motor cortex increased.

The movie itself is made using http://www.screencast-o-matic.com/

Try Stork, a research tool we developed

Stork is a publication alert app developed by us at Stanford. As a researcher we often forget to follow up important publications - and it's practically impossible to search many keywords or researchers' names everyday. Stork can help us to search everyday and notifies us when there are new publications/grants. How Stork helped me?
