Perinatal exposure of mice to a Pb, As, Cd and Cr(VI) mixture at EPA levels impaired recognition memory, raised anxiety-like behavior, and altered mPFC neuron function.

Motor deficits in the McGill-R-Thy1-APP transgenic rat model of Alzheimer's Disease

This study evaluates motor deficits in McGill-R-Thy1-APP rats, finding genotype and sex effects on motor behavior but not on spontaneous alternation.

Social evaluation of skilfulness in Tonkean macaques (Macaca tonkeana) and brown capuchins (Sapajus apella)

This study examines whether Tonkean macaques and brown capuchins can evaluate others' skilfulness by observing human actors opening food containers, finding they use social information about skill in their decisions.

Dietary ethanol affects feeding behaviour, flight performance, and mating success in a fruit-feeding butterfly

This study shows that dietary ethanol affects feeding behavior, flight performance, and mating success in the butterfly Bicyclus anynana.

Effects of commercial unflavored and vanilla-flavored e-liquids on nicotine intake and withdrawal

This study examines how unflavored and vanilla-flavored e-liquids affect nicotine intake and withdrawal in rats, finding vanilla flavor is reinforcing but does not enhance nicotine consumption or withdrawal severity.

Early-life social instability affects aggression, but not response inhibition, in chickens

This study shows that social instability increases aggression but does not affect response inhibition in chickens.

Effects of oral cannabidiol (CBD) on spontaneous opioid withdrawal in male and female rats

This study tests if oral CBD reduces opioid withdrawal symptoms in rats, finding no significant effect on physical or anxiety-like withdrawal symptoms.

Cannabidiol Reduces Oxycodone Self-Administration While Preserving Its Analgesic Efficacy in a Rat Model of Neuropathic Pain

This study shows that CBD reduces oxycodone self-administration in rats with neuropathic pain without diminishing oxycodone's pain-relieving effects.

Tsunahiki task: A newly developed group-based operant task for mice

The paper introduces a new group-based operant task for mice, showing that repeated use leads to shifts in workload toward subordinates and rank consolidation.

Ontogenic shift in the usage and function of a symbolic bird gesture

This study examines the ontogenic shift in the use of a symbolic wing-fluttering gesture in great tits, showing it functions to prompt mates to feed nestlings in adults and parents to feed fledglings.

Leptin promotes social context-specific increase in advertisement song effort of male Alston's singing mice

This study shows leptin increases song effort in male Alston's singing mice when social context is stimulating, and affects vocal amplitude but not rate.

Freely foraging macaques value information in ambiguous terrains

This study shows macaques use information-seeking as part of their foraging strategy in ambiguous terrains, with individual differences in preference for information, reward, or proximity.

Context-dependent reorganization of behavioral strategy during transfer from home-cage to head-fixed performance

This study shows mice adapt their behavioral strategies when transitioning from home-cage to head-fixed task performance, revealing context-dependent changes in behavior and strategy.

Deep behavioral phenotyping of pathogen infected mosquitoes reveals species-specific behavior changes enhancing transmission

This study uses deep learning to analyze mosquito behavior changes after infection, finding species-specific effects that could impact disease transmission.

Coordinated Discordance: Strategic Nest Attendance for Chick Rearing in Monogamous Seabird

This study examines nest attendance coordination in Streaked Shearwaters, finding that higher coordination reduces extended nest absences but not chick growth rates, with provisioning frequency and meal size being more critical for chick development.

Prenatal anti-oxidant treatment suppresses maternal immune activation induced increases in alcohol self-administration in a sex-specific manner

This study shows prenatal anti-oxidant treatment reduces maternal immune activation-induced increases in alcohol self-administration, with effects seen primarily in male offspring.

Age-trajectory of mother-infant relationships in wild Assamese macaques

This study quantifies the non-linear age-trajectory of mother-infant relationships in wild Assamese macaques, finding no sex differences and a transition to independence by mid-infancy.

A method for assessing approach and avoidance behavior across multiple olfactory stimuli in mice including multivariate hypothesis comparisons

This paper introduces a method to quantify approach/avoidance behavior in mice across multiple odors using information theory and demonstrates its application in fear conditioning experiments.

Sexual receptivity increases in synchrony with the ovulatory cycle in female medaka

This study shows that ovulation is essential for female sexual receptivity in medaka, and progesterone signaling in specific brain regions synchronizes sexual behavior with the ovulatory cycle.

Impacts of climate change on the movement ecology of an imperfect homeotherm

This study examines how climate change affects the movement patterns of giant anteaters, finding that rising temperatures reduce their movement speed and increase reliance on native forests.

Sex differences in task engagement and lapse rate during reward learning

This study investigates sex differences in reward learning by analyzing task engagement and lapse rates in rats during stimulus- and action-based learning and their reversals.

Early Changes in Respiration and Motor Activity after Spinal Cord Injury Predict Pain-Related Outcomes in Mice

This study shows that early post-injury changes in mouse respiration and motor activity can predict future pain-related outcomes after spinal cord injury.

Heightened Play following Play Observation in the Absence of 22KHz Calls in Juvenile Rats

This study investigates positive emotional contagion in juvenile rats through play observation, finding increased play behavior after observing playful demonstrators without 22 kHz calls.

Learning decouples accuracy and reaction time for rapid decisions in a transitive inference task

This study applies a drift diffusion model to analyze decision-making dynamics in a transitive inference task, showing stable reaction times despite improved accuracy during learning.

Young Asian elephant calves show differentiated social relationships with conspecifics

The paper examines social relationships between young Asian elephant calves and conspecific females, finding that calves form differentiated relationships with escorts who provide allomaternal care, while other females rarely interact with calves.
