“…It is possible that the prediction error signals prevalent in midbrain dopamine neurons may primarily drive general reward-based adaptation, whereas the value prediction error found in frontal cortical regions may facilitate model-based behavioral adaptation, as has also been suggested in our results. In addition, previous recordings directly from OFC found more diverse responses 7,43,[45][46][47][48][49][50] , presumably reflecting the cell type and hence functional diversity within OFC region 47 , calling for cell-type specific investigation, which we have performed using projection-specific imaging and manipulation in the current study.…”

Making decisions based on knowledge about causal environmental structures is a hallmark of higher cognition in mammalian brains. Despite mounting work in psychological and cognitive sciences, how the brain implements knowledge-based decision-making at neuronal circuit level remains a terra incognita. Here we established an inference-based auditory categorization task, where mice performed within-session re-categorization of stimuli by inferring the changing task rules. Using a belief-state reinforcement learning (BS-RL) model, we quantified the hidden variable associated with task knowledge. Using simultaneous two-photon population imaging and projection-specific optogenetics, we found that a subpopulation of auditory cortex (ACx) neurons encoded the hidden task-rule variable, which depended on the feedback input from orbitofrontal cortex (OFC). Chemogenetic silencing of the OFC-ACx projection specifically disrupted re-categorization performance. Finally, imaging from OFC axons within ACx revealed task state-related value signals in line with the modeled updating mechanism. Our results provide a cortical circuit mechanism underlying inference-based decision-making.

“…That both groups showed OFC modulation prior to and during a lever press suggests that initial information used to guide decision-making is still represented and may be enhanced in the OFC following alcohol dependence. Another hypothesis is that the increase in activity prior to lever press release corresponds to the greater confidence in reward delivery, something previously shown for OFC activity in cued tasks (Kepecs et al, 2008;Masset et al, 2020). This hypothesized confidence representation within OFC could be driven by reward expectation that may arise through ongoing inference processes.…”

AbstractAlcohol dependence results in neurocognitive disorders, including long-lasting deficits in decision-making processes. Neurobiological investigations have identified the orbitofrontal cortex (OFC) as a key node in inference and outcome-based decision-making, and alcohol dependence alters OFC function. However, which contributing neural computations are disrupted in alcohol dependence is unclear. Here, we combined a well-validated mouse model of alcohol dependence with in vivo extracellular recordings during decision-making. Using an action differentiation task where lever press duration is inferred from an internal associative map and made with regard to outcome value, we identified disruptions to OFC-based computations. Interestingly, alcohol dependence increased OFC activity representing inference-based lever-pressing, but decreased OFC activity during outcome devaluation. This suggests alcohol dependence induces a long-lasting disruption to OFC representations of decision-making such that action representation in enhanced, but OFC contributions to evaluating consequences is diminished. This has important implications for hypotheses regarding compulsive and habitual phenotypes observed in addiction.

Episodic memory enables recollection of past experiences to guide future behavior. Humans know which memories to trust (high confidence) and which to doubt (low confidence). How memory retrieval, memory confidence, and memory-guided decisions are related, however, is not understood. Additionally, whether animals can assess confidence in episodic memories to guide behavior is unknown. We developed a spatial episodic memory task in which rats were incentivized to gamble their time: betting more following a correct choice yielded greater reward. Rat behavior reflected memory confidence, with higher temporal bets following correct choices. We applied modern machine learning to identify a memory decision variable, and built a generative model of memories evolving over time that accurately predicted both choices and confidence reports. Our results reveal in rats an ability thought to exist exclusively in primates, and introduce a unified model of memory dynamics, retrieval, choice, and confidence.
