The ventral midline thalamic reuniens/rhomboid (ReRh) nuclei, have been implicated in contextual and spatial memory persistence. Based on its bidirectional connections with the medial prefrontal cortex (mPFC) and hippocampus, the ReRh serves as a critical relay in the transfer of information between both structures, holding a key position to regulate cortico-hippocampal interactions. This interplay is not only essential for systemic consolidation of spatial and contextual memories but might also be required in spatial working memory. Based on the idea that interactions crucial for subsequent systemic memory consolidation might also be engaged during early information acquisition, we asked if the ReRh nuclei are necessary for contextual information encoding. We used a chemogenetic ReRh inhibition (DREADD) performed before context encoding in a fear-conditioning memory task in rats. We found that pre-encoding ReRh inactivation had no impact on contextual memory formation, although DREADD silencing altered a strategy-shifting task sensitive to disruption of ReRh function. These data suggest that ReRh nuclei do not crucially participate in contextual information encoding, what challenges recent data pointing to an opposite conclusion regarding encoding of precise contextual memories or encoding of information into a working memory buffer.
