TY - JOUR T1 - A shared representation of order between encoding and recognition in visual short-term memory JF - bioRxiv DO - 10.1101/080317 SP - 080317 AU - Kristjan Kalm AU - Dennis Norris Y1 - 2016/01/01 UR - http://biorxiv.org/content/early/2016/10/12/080317.abstract N2 - Most complex tasks require people to bind individual stimuli into a sequence in short term memory (STM). For this purpose information about the order of the individual stimuli in the sequence needs to be in active and accessible form in STM over a period of few seconds. Here we investigated how the temporal order information is shared between the presentation and response phases of an STM task. We trained a classification algorithm on the fMRI activity patterns from the presentation phase of the STM task to predict the order of the items during the subsequent recognition phase. While voxels in a number of brain regions represented positional information during either presentation and recognition phases, only voxels in the lateral prefrontal cortex (PFC) and the anterior temporal lobe (ATL) represented position consistently across task phases. A shared positional code in the ATL might reflect verbal recoding of visual sequences to facilitate the maintenance of order information over several seconds. ER -
