Roles of the medial prefrontal cortex, mediodorsal thalamus, and their combined circuit for performance of the odor span task in rats: analysis of memory capacity and foraging behavior

(A) A scatterplot showing the relationship between Mean Span and Choice Latency following mdThal inactivation. Mean Span was significantly negatively correlated with Choice Latency suggesting that the memory impairment following mdThal inactivation may be partly explained by memory decay over increased latencies. (B) A scatterplot showing the relationship between Mean Span and Choice Latency following disconnection of the mPFC and mdThal. Mean Span and Choice Latency were not significantly correlated.
