The paper identifies midbrain PAG neurons that regulate courtship squeaks in female mice but not pain-elicited squeaks, suggesting distinct neural pathways for different vocalizations.

Testing and training geometrical knowledge in baboons through a conceptual categorization task

This study trains baboons on geometric concepts and finds they can learn geometric properties but do not show human-like sensitivity to geometric regularity in shape recognition tasks.

Personality and dominance shape core area use and territory-related signalling in a feral ungulate

The paper examines how personality and dominance affect core area use and territory-related signaling in Asian water buffalo.

Neonatal NMDA receptor blockade disrupts prefrontal cortical regulation of social affective behavior: implications for schizophrenia

This study shows that neonatal NMDA receptor blockade impairs social affective behavior in rats, linked to reduced parvalbumin interneurons in the medial prefrontal cortex.

Assessing Enclosure Modifications to Enhance Accessibility for Zoo-Housed Meerkats (Suricata suricatta)

This study evaluates how accessibility modifications in zoo enclosures affect meerkat behavior, finding increased use of low areas and more frequent species-appropriate sentry behavior.

Hide and seek in a rainforest canopy : when a fruit-eating carnivore (almost) met its top predator carnivore

The paper describes a rare observation of a nocturnal arboreal kinkajou being followed by a puma in a rainforest canopy.

Sex differences in agonistic social behavior: Effects of exercise and ovariectomy

This study examines how sex, exercise, and ovariectomy affect offensive and defensive aggression in rats, finding sex-specific behavioral differences and no effect of exercise.

Apparent sequential effects due to trial-to-trial fluctuations in decision criterion

This study shows that trial-to-trial fluctuations in decision criterion can explain sequential effects in decision making, challenging the assumption that these effects are caused by updates to decision parameters.

Extended Pavlovian conditioned approach training and devaluation in Long-Evans rats using time-restricted feeding

This study develops an extended Pavlovian conditioned approach paradigm in Long-Evans rats under time-restricted feeding to better identify phenotypes linked to compulsive behaviors and stress-related dysregulation.

Orsay virus infection is associated with reduced locomotion and alters cue-dependent food choice in Caenorhabditis elegans

This study shows Orsay virus infection reduces locomotion in C. elegans and alters food choice based on sensory context, with eol-1 modulating these behaviors.

A microstructural analysis of water intake patterns associated with light phase food and water restriction in male and female rats.

The paper examines how food and water intake patterns in rats change under light phase restrictions, finding that food access timing more strongly influences water intake than water access timing influences food intake.

The ontogeny of hippocampal spatial memory is supported by postnatal Cajal-Retzius cells

This study shows that postnatal Cajal-Retzius cells are crucial for stabilizing hippocampal spatial representations and adaptive behavior.

Scn2a-deficient mice exhibit serotonergic dysfunction and altered behavioral responses to psilocybin

This study shows that Scn2a-deficient mice have altered serotonergic function and different behavioral responses to psilocybin compared to wild-type mice.

Discontinuation of GLP-1RA Treatment Reinstates Binge-Like Eating and Drives Body Weight Past Pre-Treatment Levels in Mice

This study shows that stopping GLP-1RA treatment in mice with binge-like eating restores binge behavior and leads to weight gain beyond pre-treatment levels.

Distinct patterns of multisensory integration underly the expression of flavor preferences and aversions in rats

This study shows that rats integrate taste and smell signals differently depending on the valence of flavor components, challenging the MLE framework for multisensory integration.

Recruitment of intrasegmental and propriospinal interneuron networks of forelimb motor circuitry in chronic cervical contusion spinal cord injury

This study shows that PTEN inhibition improves forelimb motor recovery and circuit remodeling in chronic cervical SCI by enhancing spinal interneuron network recruitment and synaptic input.

Physical sensorimotor contingencies facilitate learning in monkeys

This study shows that rhesus monkeys learn maze-solving tasks significantly faster in a physical environment than in a virtual one, with limited performance transfer between the two.

Calves function as social magnets in a species with high fission-fusion dynamics, the Asian elephant

The study finds that calf presence in Asian elephant groups increases group size and social associations, suggesting calves promote sociality through collective defense and allomaternal care.

Dyskinesia induced by a dopamine 2 receptor-like agonist, but not a dopamine 1 receptor-like agonist, is blocked by sub-anesthetic ketamine

This study shows that sub-anesthetic ketamine reduces dyskinesia caused by D2R-like receptor agonists but not D1R-like receptor agonists in L-DOPA-primed rats.

Ranging and territoriality in African Apes

The paper compares ranging and territoriality among African apes, finding that economic defendability does not fully explain interspecific variation in territorial behavior.

Reaction-time asymmetry covaries with shifts in hand choice in macaques

This study shows that macaque hand choice and reaction time are influenced by target position, hand displacement, head rotation, and gaze direction, similar to human behavior.

Development of appropriate sensorimotor recalibration for a de novo skill

This study shows that implicit recalibration becomes flexible after prolonged training on novel sensorimotor mappings, allowing context-specific adaptation.

The anti-dyskinetic and the anti-parkinsonian effects of sub-anesthetic ketamine are also present in female preclinical models

This study shows that sub-anesthetic ketamine reduces dyskinesia and improves motor function in female preclinical models of Parkinson's disease and L-DOPA-induced dyskinesia.

Paraquat Inhalation Produces Male-Biased Dopaminergic Neuron Loss and Motor Deficits in Mice: Relevance to Parkinsons Disease

This study shows that prolonged low-dose inhalation of paraquat in mice causes male-specific dopaminergic neuron loss and motor deficits, linking it to Parkinson's disease.
