The Facial Action Coding System (FACS) is an anatomically based system to study facial expression in humans. Currently, it recognized that nonhuman animals, particularly primates, have extensive ethogram changes according the context and affective state. of great apes, closest species humans, has been studied using ChimpFACS OrangFACS as reliable tools code expressions. However, although FACS does not infer animal emotions, making additional evaluations associating with other parameters could contribute understanding expressions primates during positive or negative emotions. present review aims discuss neural correlates anatomical components emotional apes.

The growing interest in managing and recognizing pain animals has led to the search for more sensitive methods evaluate it, especially because some species conceal any visible changes associated with or are not easily assessed. Research shown that an animal's facial expression when exposed painful stimuli. Thus, developing several scales (grimace scales) such as horses, cattle, pigs, sheep, donkeys, rabbits, rats, mice, cats helped improve study of veterinary medicine. possibility using indicator is due direct relationship between activation different regions Central Nervous System somatosensory cortex, prefrontal amygdala, hippocampus, hypothalamus, their connections motor cortex elicit responses including movement muscles. present review aims discuss neurobiological association acute expressions animals. It will analyze importance characterization use grimace farm, companion, laboratory species.

Abstract Throughout modern history, animals have played a significant role in human warfare. The Imperial Japanese Navy (IJN) conducted extensive efforts to modify the natural behaviors of pigeons order enhance their utility military operations. To enable support communications aboard moving warships, IJN exposed these land-dwelling birds maritime environments, training them endure challenging conditions such as inclement weather, extreme temperatures, long-distance sea flights, and night-time navigation. During latter stages World War II, Japan faced intensified aerial bombardments, developed concealed underground pigeon lofts. This forced adapt subterranean environments. These experiments, driven by wartime demands, not only distorted pigeons’ but also seriously compromised health survival. Many died during experimentation, while even larger numbers perished on battlefield. Furthermore, prolonged shortage specialized personnel led inadequate care neglect pigeons, resulting outbreak infectious diseases then deaths that could been avoided among birds. Despite advancements technologies, continue be exploited warfare, with welfare survival ignorance. Reflecting historical lessons, it is imperative recognize warfare ethics should extend beyond rights encompass protection used

Abstract Facial expressions play a crucial role in social communication, and animals have evolved variety of signals to communicate with conspecifics. This study investigates the Relaxed Open Mouth (ROM) expression domestic dogs (Canis familiaris), conserved facial signal observed during playful interactions, by examining its variation across 30 breeds comparing it wolves lupus). Using Dog Action Coding System phylogenetic comparative methods, ROM execution was analysed determine whether domestication selective breeding influenced expression. The results reveal significant inter-breed variability execution, some exhibiting muscle recruitment closely resembling wolves, while others display distinct divergence. Notably, these differences do not always align genetic relatedness, suggesting that artificial selection has shaped expressivity ways transcend proximity. While is often linked enhanced communicative abilities, findings indicate simplified potentially due morphological constraints or pressures. novel approach could also be applied compare species existing FACS systems, including other carnivores primates.
