A CPP apparatus from Canadian Tire

15 03 2013

Carole and Agata successfully turned a $28 tool box into a conditioned placed preference apparatus for mice! Mice were trained (well semi-trained) that one substrate (sand or gravel) would be associated with a titbit of nice food, while the other would be associated with an aversive spray of water. Our mice seem too stubborn or old (they are a year old now, having been thwarting us for months) to learn much, but the ones trained with a positive stimulus on sand did come to prefer sand when given a choice. This is all part of trying to develop a murine cognitive bias task, about which (nerdy joke coming up) we are still optimistic. Tool_Box_Mice
