ABSTRACT Handling motor noise is fundamental to successful sensorimotor behavior, especially in high-risk situations. Research using finger-pointing tasks shows that humans account for and costs of potential outcomes movement planning. However, does this mechanism generalize more complex tasks? Here, we investigate behavior under risk throwing across three experiments with 20 participants each. Their task was throw balls at a target circle, partially overlapped by penalty circle. This challenged find strategies trade off penalties rewards. In the experiments, magnitude distance between circles were manipulated. We measured location their final gaze fixation before movement—as an indicator planned aiming point—and ball’s impact location. Without penalty, both centered on target. condition, participants’ fixations shifted away from larger shifts higher smaller distances. Interestingly, locations not only (“more conservative”) but also closer statistically optimal (expected gain-maximizing) compared fixated aim points. Movement trajectory analyses show that, conditions, zone increased until phases movement. These results suggest evaluation completed pre-movement planning phase further optimized during execution.

The current understanding of primate natural action organization derives from laboratory experiments in restrained contexts (RCs) under the assumption that this knowledge generalizes to freely moving (FMCs). In work, we developed a neurobehavioral platform enable wireless recording same premotor neurons both RCs and FMCs. Neurons often encoded hand mouth actions differently Furthermore, FMCs, identified cells selectively untestable during others displayed mixed selectivity for multiple actions, which is compatible with an based on cortical motor synergies at different levels complexity. Cross-context decoding demonstrated neural activity FMCs richer more generalizable than RCs, suggests neuroethological approaches are better suited unveil bases behavior.

The current study sought to advance our understanding of the connections between stress, perceived control, affect, and physiology in daily life. To achieve this goal, we integrated hourly ambulatory physiological experiential data from young adult participants who experienced work or academic stressors over course a day. Participants wore cardiovascular monitor that recorded heart rate continuously for 8 h while random Ecological Momentary Assessment (EMA) were collected personally relevant settings via mobile phones learn about affect. findings provide critical by demonstrating clear evidence moderation wherein affective wellbeing was strongly associated with when one stressor outside their control. innovative approach utilized real-world provides further support value integrating individuals' self-report experiences (e.g., role control), as information gained can insights into stress rate) negative affect) connections. present thus literature connecting on streams.

ABSTRACT Most of our understanding fish locomotion has focused on elementary behaviors such as steady swimming and escape responses in simple environments. As the field matures, increasing attention is being paid to transient unsteady that characterize more complex interactions with environment. This Commentary advocates for an ecologically relevant approach lab studies. Specific examples have brought new energetic consequences swimming, (1) station holding around bluff bodies, which departs drastically from almost all aspects kinematics, muscle activity energetics, (2) acceleration feeding, are critical survival but often neglected because challenges measuring costs.

Brain plasticity and behavioral compensation after neurological injury offer promising clinical potential for targeted functional neurorehabilitation. An active area of research in neurorehabilitation is vision restoration via perceptual learning. Despite exciting success stories, rehabilitation strategies have faced limitations achieving longevity generalization beyond the training parameters. In this chapter, we propose that learning involves more than just sensory brain regions, suggesting search neural mechanisms visual should expand system. We hypothesize engaging cognitive circuits with a navigation paradigm encoding promotes system, key input to brain’s networks. Under hypothesis, an integrated approach where systems are dynamically interacting. Furthermore, argue studying functions context necessitates controlled omission experimental paradigms, such studies implications designing effective rehabilitative patients cortical blindness. review animal on without input, focusing hippocampal formation posterior parietal cortex-brain regions thought subserve spatial navigation.

Abstract Experiments tracking hippocampal place cells in mice navigating the same real environment have found significant changes neural representations over days. However, there is currently a debate whether such “representational drift” serves an intrinsic function, as distinguishing similar experiences occurring at different times, or instead observed due to subtle differences sensory behavior. Here, we used experimental control offered by multisensory virtual reality (VR) system determine that behavior do not detectably change drift rate. We also excitability of individual was most predictive their representational subsequent days, with more excitable exhibiting less drift. These findings establish occurs even highly reproducible environments and highlight neuronal key factor long-term stability.
