Brainbow by Maria Bergamasco (IMAGE) Walter and Eliza Hall Institute Caption The higher cortex is responsible for complex brain functions, such as critical thinking and problem solving. The colors of the Brainbow in this image each represent a different layer of the higher cortex of the brain during development. The primary colors have been selected specifically to avoid confusion when colors overlap. Where red overlaps with blue, we can clearly see purple. By coloring and layering brain tissue, Maria can study the impact of disrupting or altering genes at different stages of brain development. This will help her to discover what goes wrong in cases where the higher cortex doesn't function as it should. Understanding what goes awry in early brain development enables better diagnosis and treatment for people with intellectual disabilities.
