Summary: This study identified causal effects on percept dynamics in three PFC activities and highlighted the distinct functions of the DLPFC and IFC in brain state dynamics. The findings emphasize the importance of monitoring brain states for a better understanding and control of neural pathways underlying perception and behavior.

Summary: Using single-neuron recordings, electroencephalographic recordings, and computational methods, the researchers found that conscious experience and self-reflection are related to a common mechanism of evidence accumulation in the posterior parietal cortex.

Summary: Balancing short-term speed and accuracy is crucial for making optimal decisions in the presence of noise. This study demonstrates the importance of long-term learning in the speed-accuracy trade-off and provides a theoretical framework that incorporates learning dynamics. The findings reveal that choosing suboptimal response times to facilitate faster learning can lead to greater total reward, suggesting cognitive control over the learning process.

Summary: The interaction between reward and the noradrenergic (NA) system in shaping performance is not clear. This study found that increasing reward or NA levels enhanced engagement in a task and improved response speed and consistency. High reward further reduced impulsive responses, while atomoxetine (ATX) increased movement duration and helped regulate energy expenditure through the NA system.

Summary: This study found that unilateral inactivation of the superior colliculus in monkeys leads to decision biases and changes in reaction times, indicating that brainstem structures play a crucial role in perceptual decision-making in primates.

Summary: A Bayesian framework based on partially observable Markov decision processes (POMDPs) can accurately predict subjects' confidence and explain discrepancies between confidence and choice accuracy in perceptual decision making tasks. These discrepancies are not due to sub-optimal inference or discrepant computational processes, but rather arise from incomplete knowledge of the environment.

Summary: The modality of movement selection may influence the brain networks involved during the execution phase, with freely chosen movements showing increased activation in the pre-supplementary motor area, parietal, and cerebellar regions. Freely chosen movements also exhibit increased information flow between the right posterior parietal cortex and the cerebellum compared to instructed movements. This suggests that the parieto-cerebellar network is particularly engaged during freely chosen movements to monitor the congruence between intentional content and outcome.

Summary: Prudently choosing who to interact with and who to avoid is crucial for benefiting from cooperative interactions. This study found that observing how potential partners plan and execute actions during decision-making can provide helpful cues for partner choice. Participants preferred to interact with individuals who planned actions quickly or executed actions with direct and smooth movements, indicating confident and deliberate cooperation.

Summary: Human cognition allows adaptive decisions based on limited prior experiences, and the hippocampus plays a key role in supporting value-based social choices and memory for individuals. It is sensitive to the perception of others and their treatment during choices, aiding in flexible interactions with generous individuals and avoidance of selfish ones. The hippocampus leverages past choices to solidify neural signatures for future adaptive behavior in social learning.

Summary: This paper presents a temporal-spatial causal interpretation (TSCI) model to understand the long-term behavior of reinforcement learning (RL) agents. The model can discover task-relevant temporal-spatial information and provide valuable causal interpretations for vision-based RL agents from the temporal perspective.

Summary: This paper explores how human drivers make reliable decisions in uncertain environments. By utilizing an explainable artificial intelligence method and entropy-based measures, it reveals the changes in perceptual uncertainty during the execution of interactive tasks, demonstrating that human drivers actively seek information to reduce perceptual uncertainty and make trustworthy decisions.

Summary: This study found that random motion stimuli can influence the choices made by participants, leading to biased decisions. The consistent choice bias among participants is caused by subtle motion information contained in the motion noise. The implications of this finding for future studies of perceptual decision making are discussed, suggesting the use of a stimulus-informed modeling approach to control for the effects of apparent decision evidence in random stimuli.

Summary: The right temporo-parietal junction (rTPJ) and the right lateral prefrontal cortex (rLPFC) play significant roles in balancing fairness norms and selfish interests in human social behavior. Theta oscillations in rTPJ strengthen the aversion to unequal splits, while theta oscillations in rLPFC enhance the preference for outcome-maximizing unequal choices, especially for disadvantageous outcome distributions.
