Summary: This protocol introduces a chronic implantation method for recording neural activity in mice and rats using Neuropixels probes, facilitated by compact and reusable 3D-printed fixtures for stable chronic recordings. Probes can be safely recovered for reimplantation through a dedicated retrieval mechanism, enabling longitudinal large-scale single-unit data acquisition for cost-efficient studies in systems neuroscience.

Summary: The present study aimed to validate a series of automated assays to monitor the effects of chronic exposure to nanoplastics on fish. Adult goldfish were exposed to 100 μg/L polystyrene nanoparticles (PS-NPs) for 30 days. The results showed that NPs triggered immune and antioxidant responses in the gills, but had no significant effect on the brain and muscle. These findings suggest that gills may be the primary target for NPs and further investigation is needed to understand the cascading effects on gas exchange and osmo-ionic regulation.

Summary: This study investigated whether rubber tips from artificial sports fields could become marine microplastics. It was found that rubber tips migrated from artificial turf to surrounding ditches and were ingested by goldfish in an experiment. The presence of rubber tips in sediments suggests that they can be released into rivers and eventually reach the ocean. Goldfish ingested rubber tips with or without fish feed, but they discharged them within 48 hours, indicating that ingestion was an active behavior. Therefore, artificial turf sports fields may be a source of marine microplastics and pose hazardous effects on wild fish through ingestion.

Summary: Current methods for recording single-cell activity in freely-moving mice require either head fixation or attachment of a device, both of which may alter behavior. This study presents a new recording method that allows cortical activity mapping without mechanical restrictions on mouse movement.

Summary: In this article, scaling laws for undulatory swimmers are proposed, relating beat frequency to length considering muscle biology and fluid interaction. The results support the idea that frequency tuning is the primary means by which a swimmer selects its speed, and highlight the influence of size on frequency regulation.

Summary: This study investigates the relationships between the swimming behaviors of different fish species and the three-dimensional hydrodynamic field. A model of three-dimensional swimming corridors corresponding to fish swimming characteristics is constructed. The model is verified through a fish acoustic telemetry experiment. The study provides scientific basis for the layout of fish-crossing facilities and operation of reservoirs during the fish spawning season.

Summary: The study compared verbal reporting and exclusion in two different conditions and found that the measurement results varied between the two conditions. In the intermittent reporting group, verbal reporting showed more explicit re-aiming while exclusion showed less implicit adaptation. However, after the end of learning, the differences between the two methods were no longer apparent.

Summary: Recognition and categorization of individual objects is a complex computational task, but visual systems can perform it rapidly and accurately. Archerfish, a species that hunts by shooting water at aerial targets, has the ability to recognize natural objects and categorize them into relevant classes. They can also recognize individual objects under different conditions. A computational model based on object features and a machine learning classifier reveals that a small number of features and object contours play a key role in object categorization. Behavioral experiments validate these findings.

Summary: Many funding agencies have emphasized the importance of considering sex as a biological variable in experimental design to improve the reproducibility and translational relevance of preclinical research. Omitting the female sex from experimental designs in neuroscience and pharmacology can result in biased or limited understanding of disease mechanisms. This article provides methodological considerations for incorporating sex as a biological variable in in vitro and in vivo experiments, including the influence of age and hormone levels, and proposes strategies to enhance methodological rigor and translational relevance in preclinical research.
