Summary: This article discusses the role of brain circuits in forming cognitive maps to process and store statistical relationships in the environment, proposing the concepts of prospective and retrospective cognitive maps. Cognitive maps describe environmental states and their relationships, influencing many neural signals and behaviors.

Summary: This study reveals a functional opposition between the dorsomedial and dorsolateral striatum during skill and habit formation. Loss of function in the dorsomedial striatum accelerates sequence acquisition, while loss of function in the dorsolateral striatum impedes it. The mPFC is not involved, but the lateral orbitofrontal cortex plays a critical role.

Summary: Behavioral control consists of parallel systems, model based and model free, and the anterior cingulate cortex plays a critical role in predicting actions and their consequences. ACC represents the complete state space of a task and is necessary for updating model-based strategies.

Summary: This study identified the key role of the infralimbic (IL) region of the medial prefrontal cortex (mPFC) in regulating fear extinction. By infusing the D2 receptor antagonist sulpiride into the IL region, auditory fear extinction was enhanced in an inverted U-shape pattern, with moderate doses being most effective.

Summary: The reciprocal connectivity between the medial prefrontal cortex (mPFC) and the dorsal raphe nucleus (DR) plays a role in mood control and stress resilience. The infralimbic subdivision (IL) of the mPFC, similar to the ventral anterior cingulate cortex, is associated with major depressive disorder (MDD). Stimulation of IL suppresses serotonergic activity more than stimulation of PrL, indicating the differential control of serotonergic activity by these two subdivisions.

Summary: The prelimbic cortex (PrL) is crucial for encoding and expressing contextual fear memory. Protein kinase M zeta (PKM zeta) has been shown to maintain memories by inhibiting the endocytosis of GluA2-containing AMPA receptors. This study found that acute inhibition of GluA2-dependent AMPAR endocytosis in the PrL does not affect recent or remote contextual fear memory maintenance. However, inhibition of PKM zeta in the PrL at a remote time point disrupts contextual fear memory maintenance, which can be prevented by blocking GluA2-dependent removal of AMPARs.

Summary: This study compared collateral projections from different rostral thalamic nuclei terminating in different cortical areas. The results showed that these projections predominantly arise from separate populations of neurons with discrete cortical termination zones.

Summary: The study found that inactivation of specific PFC sub-regions or the caudate nucleus can impair the response to contingency changes, enhancing it in some cases, while overactivation of certain regions can also impair this response. These findings demonstrate the distinct roles of different PFC sub-regions in goal-directed behavior and provide insights into potential neurobehavioral substrates of psychiatric disorders such as obsessive-compulsive disorder.

Summary: Accumulating evidence suggests that the medial prefrontal cortex (mPFC) plays a crucial role in the acquisition of fear memory during trace fear conditioning. Specifically, the prelimbic (PL) subregion within the mPFC is involved in short- and long-term trace fear memory formation. Furthermore, NMDA receptor-mediated neurotransmission in PL is required for the acquisition of trace fear memory.

Summary: This article reviewed the behavioral neuroscience of extinction, highlighting that both Pavlovian and operant extinction rely on new inhibitory learning rather than erasure of original learning. Neural circuitry involved in Pavlovian extinction includes the amygdala, prefrontal cortex, and hippocampus, while instrumental extinction involves distinct ensembles in corticostriatal, striatopallidal, and striatohypothalamic circuits. Despite significant progress in the field in recent decades, a fully integrated biobehavioral understanding is still pending.

Summary: The dense fiber pathways connecting the insular cortex with frontal cortices are crucial for executive functions. We used neuroanatomical tracing in rats to map the detailed organization of projections from the insular cortex to orbitofrontal and medial prefrontal cortex. Different parts of the insular cortex project to distinct regions of the frontal cortices, with primary gustatory cortex projections avoiding the mPFC. These findings provide insights into the role of the insular cortex in interoceptive processing and executive control.

Summary: The study found that in the dorsal hippocampus and prelimbic cortex of male rats, after inhibitory avoidance learning, transcriptomic profiles showed significant regional specificity and changes in transcription pathways. While there was some overlap in the transcriptome profiles of these two regions during learning, the main regulated biological pathways were significantly different.

Summary: Decision-making requires different aspects of information and involves multiple cognitive processes. The rodent medial prefrontal cortex (mPFC) is believed to play a central role in these abilities. Previous studies on mPFC function have yielded controversial results, but this study with rats performing an economic decision task revealed four distinct functional domains within mPFC, closely related to anatomical subregions. Dorsal mPFC regions were more involved in processing active decisions, while ventral regions were more engaged in motivational factors.

Summary: The study found that rats overexpressing PARKIN gene have stronger self-administration ability for METH, while rats with PARKIN knockout are more prone to self-administer METH. This result provides useful models for studying the neural substrates underlying resilience or vulnerability to METH use disorder and identifies PARKIN as a novel potential drug target for treating heavy use of METH.

Summary: Impulsivity was increased in all rats following short abstinence from cocaine, with male rats showing higher impulsivity if they had a higher ratio of excited to inhibited neurons in the PrL at the start of the task.
Male rats exhibited a shift in impulsivity following short abstinence, as PrL activity became more inhibited, while PrL activity did not track impulsivity in female rats.

Summary: This study examined the effects of shifts in motivation from hunger to satiety on outcome-selective Pavlovian-instrumental transfer (sPIT) in rats. The results showed that motivational downshift induced by outcome devaluation did not affect the sPIT effect, but other forms of motivational downshift reduced overall lever responding and magazine entries, as well as the sPIT effect.
