Three-Dimensional Clay Modeling of Subcortical Brain Structures around 3D Printed Ventricle Models
A lab activity was created using modeling clay to create subcortical brain structures around purchased ventricle models to better understand spatial locations of difficult structures of the brain. An instructional guide was created complete with a reference sheet with sketched proportions and shapes of structures and a picture of a completed clay/ventricle model. A pretest, posttest, and likeability survey was given to measure the effectiveness of the activity as well as its enjoyableness. There was a significant difference in the mean pretest scores and the mean posttest scores, t(12)=-5.63, p<.001. Because of difficulties with Play-Doh, such as staying together, hardening, and even sometimes harming the ventricle models, different types of clays were tested in modeling. Each clay was judged in color availability (each structure uses a different color), ease of shaping, stickiness (good or bad), shape retention, and ease of cleanup. The top two clays were Cernit and Sculptey.
