A novel naive Bayes approach to identifying grooming behaviors in the force-plate actometric platform

The paper introduces a naive Bayes classifier to automate grooming behavior analysis in mice using force-plate actometry, achieving high accuracy and demonstrating its utility in tic disorder models.

A Framework for Relating Natural Movement to Length and Quality of Life in Human and Non-human Animals

The paper proposes a theoretical framework to quantify natural movement in animals and relate it to length and quality of life, validated in Drosophila.

Nociception in chicken embryos, Part II: Embryonal development of electroencephalic neuronal activity in ovo as a prerequisite for nociception

The paper investigates the development of electroencephalic neuronal activity in chicken embryos to determine when nociception might begin, finding that noxious stimuli may be processed by day 13.

Variability of wheel running behavior in mice is dependent on housing, sex, and genetic background

This study examines how housing conditions, sex, and genetic background affect wheel running behavior in mice, finding sex- and housing-specific differences in wheel usage.

Sex-specific Stress and Behavioural Responses to Human Experimenters in Rats

This study shows that female rats show increased anxiety and stress responses when exposed to male experimenters, with associated hormonal changes, highlighting the need to standardize experimenter sex reporting in research.

Effect of electrical hybrid-frequency water bath stunning on the spontaneous electroencephalogram (EEG) and electrocardiogram (ECG) of broilers

This study compares the effects of a hybrid-frequency electrical stunning method with a single-frequency method on EEG and ECG of broilers, finding epileptic EEG patterns and suggesting potential benefits for meat quality and welfare.

RNA-seq and differential expression analysis of the duck transcriptome: The effect of short-term cage-rearing

This study compares gene expression in duck hypothalamus and pituitary between cage-reared and floor-water system-reared ducks, identifying differentially expressed genes and pathways affected by short-term cage-rearing.

Rejection in early life is associated with high and long-lasting stress and higher incidence of infections in owl monkeys

The paper examines the long-term effects of maternal rejection in owl monkeys, finding higher stress levels and infection rates in rejected infants compared to controls.

Conserved abilities of individual recognition and genetically modulated social responses in young chicks (Gallus gallus)

The paper studies social behavior in young chicks, finding that social motivation varies genetically while the ability to recognize individuals is more conserved across breeds.
