The paper identifies the SuM[->]LPO pathway as a circuit that modulates dopamine release and active behavior through interactions with mesolimbic dopamine signaling.

This study identifies a cortical circuit involving ACC-D1+ neurons critical for initiating goal-directed movements and shows its therapeutic potential in Parkinsonian akinesia.

This study shows that TSP1 and TSP2 from astrocytes are essential for synapse development and effort control during operant conditioning in mice.

This study shows that training-induced excitatory synaptogenesis in the ACC->DMS circuit is required for effort control, not learning, and is mediated by the 2{delta}-1 protein.

This study shows that prefrontal cortex inactivation impairs mnemonic discrimination in a similarity task regardless of lure novelty, unlike hippocampal inactivation.

This study investigates how muscimol-induced hippocampal excitation affects mnemonic discrimination in rats, finding that it impairs performance on novel stimuli but not familiar ones.
