From wag to affect: Tail kinematic signatures of canine emotional states in computer-controlled environments

This study utilizes computer-controlled tasks and pose-tracking to reveal that while dogs are more likely to wag their tails during positive anticipation, tail kinematics in negative contexts reflect arousal rather than valence, suggesting that tail wagging may be primarily a social signal rather than a universal indicator of emotional state.

Acquisition and extinction of drug-context memories are linked to distinct epigenetic and transcriptional mechanisms in the mouse dentate gyrus

This study demonstrates that in the mouse dorsal dentate gyrus, the acquisition and extinction of cocaine-context memories engage fundamentally distinct, non-overlapping epigenetic and transcriptional mechanisms, providing a molecular basis for why extinction suppresses rather than erases drug memories.

A Multidimensional Framework for Behavioral Persistence: Dissociable Dimensions of Effort, Endurance, and Sequence Stability in Mice

This study introduces the PERCS framework to deconstruct behavioral persistence into five dissociable dimensions, demonstrating through mouse operant conditioning that unrewarded effort, rather than reward delivery, drives persistent behavior and that distinct task schedules differentially shape these dimensions to reveal stable phenotypic profiles.

Genetic ablation of visual perception reveals behaviour changes in male and female malaria mosquitoes

This study demonstrates that genetically ablating the Tan enzyme in *Anopheles* mosquitoes impairs their visual processing, leading to reduced light-dependent attraction and altered behaviors in both males and females, thereby highlighting the critical role of vision in host-seeking and mating while offering new avenues for vector control strategies.

Safety Signals Enable Single-Episode Active Avoidance paradigm and Expose Threat Generalization in Tuberous Sclerosis Complex

This study introduces a single-episode active avoidance paradigm to demonstrate that oxytocin-modulated translational control in the medial prefrontal cortex is essential for stabilizing threat-safety discrimination, as its disruption by excessive threat or Tsc2 haploinsufficiency leads to pathological avoidance generalization in Tuberous Sclerosis Complex.

Between Behaviors: Comparison of Two Dynamical Models of Behavioral Switching for \textit{C. Elegans} Locomotion

This paper compares two distinct dynamical models of *C. elegans* behavioral switching to demonstrate how fundamentally different mechanisms can produce similar noisy phenomena, while clarifying their deterministic differences and proposing extensions to incorporate state dwell times for a broader theoretical understanding of adaptive systems.

Voluntary wheel running provides pain relief but transiently exacerbates gait impairments in male and female mice with unilateral osteoarthritis

This study demonstrates that while voluntary wheel running provides pain relief for mice with unilateral osteoarthritis, it simultaneously causes a sex-dependent decline in activity levels and transiently worsens gait impairments, highlighting a critical trade-off between analgesic benefits and functional outcomes in exercise-based therapeutic strategies.

Music exposure reduces anxiety- and depression-like behavior in rodents: a systematic review and multilevel meta-analysis

This systematic review and multilevel meta-analysis of 20 rodent studies reveals that music exposure significantly reduces average anxiety- and depression-like behaviors by approximately 18%, while its effects on inter-individual behavioral variability depend on the specific assay type and music genre rather than showing a uniform change.

Maternal preconception calorie restriction reprograms coping strategies, socio-sexual behaviour, and endocrine function in adult rat offspring

This study demonstrates that distinct patterns of maternal preconception calorie restriction in rats differentially program adult offspring, inducing a prosocial, sexually motivated phenotype in males and an enhanced active coping style in females, alongside specific alterations in hypothalamic-pituitary-gonadal axis function.
