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) Mean (±SEM) Choice Latency following infusions of Saline or M/B into the mdThal. Inactivation of the mdThal caused a large and significant increase in Choice Latency. (B) Mean (±SEM) mEP following infusions of Saline or M/B into the mdThal. Inactivation of the mdThal caused no significant change in mean error position. (C) Mean (±SEM) %AppE following infusions of Saline or M/B into the mdThal. Inactivation of the mdThal caused no significant change in the percentage of total approaches accounted for by the error odor. (D) Mean (±SEM) App/O following infusions of Saline or M/B into the mdThal. Inactivation of the mdThal caused rats to make significantly fewer approaches per odor.
