Read full description

Players are tasked with trying to find different regions of the brain in three different stages. It's a fun way to familiarise yourself with where the brain regions are located and what their function is. In the first stage, players drive a campervan across the outside of the brain to explore different regions. In the second stage, players are tasked with using that same campervan to explore the inner reaches of the brain. And finally, in the third stage, players are asked to locate brain regions according to the function that the brain region performs. Teachers can use this app to better understand which regions of the brain students are having difficulty with.
