What is it about?
Even though our vision is at its very best in terms of acuity and resolution near our line of sight (where our gaze is currently directed), we found that we are paradoxically quite poor when trying to recall locations at our gaze direction from short term memory.

Why is it important?
Even though humans heavily rely on foveal vision (vision through the part of the image where our gaze is directed), the mechanisms associated with foveal vision remain poorly understood. This has historically been the case due to difficulty in studying very small visual image regions in the fovea. Moreover, despite decades of research, the brain mechanisms for short term memory maintenance remain to be debated. Our results link two enigmatic fields (foveal vision and short term memory representations) by revealing a highly unexpected finding. With this finding, we specifically clarify the mechanisms with which short term memory can be implemented on existing sensory and motor neural substrates representing our spatial environment.
