It has recently been shown that a Barnes maze adapted for juvenile rats can be used to assess the maturation of spatial learning and memory, as spatial navigation ability first emerges around the end of the third postnatal week (McHail et al., 2018).

The maze adapted for juvenile rats consists of a round white platform that is smaller than the adult maze with eight evenly spaced holes around the perimeter, a reduced number of perimeter holes compared to the adult apparatus. Distal visual cues (extra-maze contextual cues) are placed around the maze and used by the animal to determine the spatial location of an escape box hidden underneath one of the perimeter holes. These spatial cues are enlarged to allow better visualization for the younger animals.
