ABSTRACTIt remains unclear how and to what extent non-human animals make demanding on-the-fly predictions during pursuit. We studied this problem in a novel laboratory pursuit task that incentivizes prediction of future prey positions. We trained three macaques to perform joystick-controlled pursuit of prey that followed intelligent escape algorithms. Subjects reliably aimed towards the prey’s likely future positions, indicating that they generate internal predictions and use those predictions to guide behavior. We then developed a generative model that explains real-time pursuit trajectories and showed that our subjects use prey position, velocity, and acceleration to make predictions. We identified neurons in the dorsal anterior cingulate cortex (dACC) whose responses track these three variables. These neurons multiplexed prediction-related variables with a distinct and explicit representation of the prey’s future position. Our results provide a clear demonstration that the brain can explicitly represent future predictions and highlight the critical role of anterior cingulate cortex for future-oriented cognition.One-sentence summaryIn a dynamic pursuit environment, monkeys actively predict future prey positions and dACC neurons encode these future positions.

Dorsal Anterior Cingulate Cortex

AbstractThe error-related negativity (ERN) is a response-locked event-related potential, occurring approximately 50 ms following an erroneous response at frontocentral electrode sites. Source localization and functional magnetic resonance imaging (fMRI) research indicate that the ERN is likely generated by activity in the dorsal anterior cingulate cortex (dACC). The dACC is thought to be a part of a broader network of brain regions that collectively comprise an error-monitoring network. However, little is known about how intrinsic connectivity within the dACC-based error-monitoring network contributes to variability in ERN amplitude. The purpose of this study was to assess the relationship between dACC functional connectivity and ERN amplitude. In a sample of 53 highly trait-anxious individuals, the ERN was elicited in a flanker task and functional connectivity was assessed in a 10-minute resting-state fMRI scan. Results suggest that the strength of dACC seeded functional connectivity with the supplementary motor area is correlated with the ΔERN (i.e., incorrect – correct responses) amplitude such that greater ΔERN amplitude was accompanied by greater functional coupling between these regions. In addition to the dACC, exploratory analyses found that functional connectivity in the caudate, cerebellum, and a number of regions in the error-monitoring network were linked to variability in ΔERN amplitude. In sum, ERN amplitude appears to be related to the strength of functional connectivity between error-monitoring and motor control regions of the brain.

Information Sampling

Neural activity in anterior cingulate cortex and the anterior striatum predicts which visual objects are sampled and how likely objects are paired with positive or aversive outcomes. We causally tested whether these neural signals contribute to behavioral flexibility. Disrupting with transcranial ultrasound the ACC, but not striatum, prolonged information sampling when attentional demands were high, impaired flexible learning, and reduced the ability to avoid losses. These results support a role of the ACC in guiding attention and information sampling to overcome motivational conflict during adaptive behaviors.
