Summary: Certain life stressors can have lasting physiological and behavioral effects by causing significant shifts in monoamine neurotransmitters. Reduced PMAT function enhances the responsiveness to stressors in mice, and male heterozygotes exhibit malleable fear behaviors after prior stressor or sham stress exposure.

Summary: Innovations in animal care in livestock production are increasingly relying on automation and bidirectional communication between animals and machines. The current learning progress metrics are not transferable and a normalized precision metric is proposed as an alternative. This metric provides a more accurate assessment of animal learning performance and facilitates the integration of animals in management tasks.

Summary: An escapable/inescapable stress paradigm was used to study the effects of behavioral control and repeated footshock stressors on adult neurogenesis and cognitive function. The results showed that stressed mice with behavioral control had short-term escalation in neurogenesis, while stressed mice without control showed no change compared to non-stressed mice. Corticosterone levels were similar in both groups. Furthermore, the number of 6-week-old and functionally-integrated neurons in the dorsal dentate gyrus seemed to be related to spatial location working memory quality.

Summary: The study aimed to determine the motivation of pasture housed dairy heifers to access shade during summer and autumn in southern Brazil. It found that heifers valued shade, especially in hot summer days, and that social rank influenced shade use. Higher ranked heifers displaced others more often and spent more time in shaded areas, particularly those with trees and shade cloth.

Summary: The brain's physiological response to reward expectations differs based on the level of expectation. While it is known that better-than-expected outcomes are quantitatively encoded via midbrain dopaminergic (DA) activity, it is less clear whether worse-than-expected outcomes are expressed in the same way. This study shows that larger reward expectations for unexpected reward omissions are associated with a slower increase and larger decrease (DA dip) in the DA concentration at the ventral striatum in mice. The findings suggest that the DA dip amplitude represents the degree of reward expectations and may guide behavioral adjustment.

Summary: This study found that budgerigar TIN detection thresholds are similar to human thresholds, with minimal impact from challenging roving-level conditions. Many midbrain neurons showed decreasing response rates as TIN signal-to-noise ratio was increased, attributed to amplitude-modulation tuning and flatter amplitude envelopes in higher SNR tone-plus-noise stimuli.

Summary: Despite the involvement of donkeys in various activities with humans, their cognitive and learning abilities are still poorly understood. This pilot study applied an operant conditioning task to explore donkeys' learning abilities and evaluated the impact of different factors on their performance. The findings provide insights into donkeys' learning capabilities and highlight the importance of considering intrinsic animal characteristics in training programs.

Summary: Studies using zebrafish in neuro-behavioural research are increasing, with computational methods being one of the most efficient ways to measure fish behavior. The automated system allows for conditioning and assessment of zebrafish behavior, providing greater stability in experiments and individual fish analysis.

Summary: Operant chambers are important tools in animal research for studying cognition, motivation, and learning processes. This article introduces a custom-built operant chamber that is relatively low-cost and suitable for complex behavioral tasks, while also supporting video behavior imaging and calcium imaging. The study shows that using this operant chamber can replicate previous findings and validate inhibitory control impairments in mice. Compared to other open-source alternatives and commercially available counterparts, this operant chamber offers a lower cost and better balance.

Summary: The study found that female pygmy slow lorises are more social than previously thought, preferring close social interactions with conspecifics and having a consistent nesting habit. Housing female pygmy slow lorises in same-sex groups can enhance their social behaviors and improve their well-being.

Summary: The purpose of this study was to apply deep and slow breathing techniques to elderly individuals, classified as potential dementia patients, and examine their effects on learning and memory cognitive functions. The study involved 45 elderly subjects divided into a rest group, a before group, and an after group. Measurements of cognitive abilities were taken before testing, 30 minutes after learning, and 24 hours after learning. The findings showed significant improvements in retention, attention, working memory, and spatial perception, confirming the benefit of deep and slow breathing in dementia prevention training.

Summary: This study found that a 6-week slow, deep breathing (SDB) intervention improved symptoms and altered rectal sensation in constipation-predominant IBS (IBS-C) patients. Additionally, SDB enhanced vagal activity, suggesting that the effect of SDB on IBS-C may be due to mechanisms involving autonomic responses.

Summary: This study developed a model using deep learning technology to monitor poultry behavior and analyzed the performance of different convolutional neural networks in broiler behavior recognition at different days. The results showed that the DenseNet-264 network performed the best, and introducing the efficient channel attention mechanism further improved its accuracy rates.

Summary: This study introduces a framework for predicting the calving time of dairy cows using sensor data and deep learning models. Results indicate that the framework can efficiently predict calving within shorter time frames and performs well even in the presence of missing data.
