Memory Deficits (IMAGE) University of California - Riverside Caption Working memory deficit one week after brain injury. The image shows the swimming path of a rat released in a water maze at the arrow trying to find a hidden platform P on first trial (sample) and a minute later (choice). The uninjured rat (sham) moves rapidly to the platform showing it remembers the location (good spatial working memory). The injured rat (FPI) has difficulty remembering the location of the platform. Color code below indicates time spent at a location. The trajectory shows the path taken and is color coded for time spent at any given spot. Credit Santhakumar lab, UC Riverside.
