Task-specific oscillatory synchronization of prefrontal cortex, nucleus reuniens and hippocampus during working memory. De Moji-van Malsen et al.

Description

Theta power and running speed during DNMTS working memory task: During a Delayed Non Match To Sample (DNMTS) working memory task inside a automated touch screen chamber lfp data for hippocampal CA1 region, nucleus reuniens and the medial prefrontal cortex were acquired in mice. Besides this a video of the behavior was recorded. Since hippocampal theta oscillations have been associated with running speed, we tested whether running speed differed between the task "must touch" (MT) and the actual working memory task ("DNMTS"). Furthermore the correlation of running speed and and CA1 theta power was analyzed. Changes in oscillatory coherence between mPFC,nRE and vCA1 over time during a working memory task : During a Delayed Non Match To Sample (DNMTS) working memory task inside a automated touch screen chamber lfp data for hippocampal CA1 region, nucleus reuniens and the medial prefrontal cortex were acquired in mice. We calculated time varying coherence between the regions during the delay (6 sec) period between the presentation of the sample location and the presentation of the sample and target location (non match to sample).
