Summary of studies examining cognition in rodent models of TBI. This field has been studied extensively, so by necessity our table omits several published works from 2014 and for published work prior, readers are directed to detailed reviews (Paterno et al., 2017; Tucker et al., 2018). MWM- Morris water maze, RAM- Radial 8-arm maze.
