Oxytocin has been well researched in association with psychological variables and is widely accepted as a key modulator of human social behaviour. Previous work indicates involvement of oxytocin receptor gene () single nucleotide polymorphisms (SNPs) in human-human empathy, however little is known about associations of SNPs with empathy and affective reactions of humans towards animals. Five SNPs previously found to associate with human social behaviour were genotyped in 161 students. Empathy towards animals and implicit associations were evaluated. A General Linear Model was used to investigate the alleles and allelic combinations along with socio-demographic variables and their influence on empathy towards animals. Empathy towards animals showed a significant association with SNP rs2254298; homozygous G individuals reported higher levels of empathy towards animals than heterozygous (GA). Our preliminary findings show, for the first time, that between allelic variation in and animal directed empathy in humans maybe associated, suggesting that social behaviour role crosses species boundaries, warranting independent replication.

Background: Empathy is a complex behavior enabling individuals to recognize and sense the emotional situation of others. Empathy requires cognitive, emotional, and learning abilities to understand and react to the suffering of others. The current study evaluates the effect of Amyloid-Beta (Aβ), an aggregated peptide involved in Alzheimer's disease on empathy-like behavior.

The increasing prevalence of methamphetamine abuse among women, particularly pregnant females, is a global concern. Methamphetamine can readily cross anatomical barriers like the blood-placenta barrier and cause detrimental impacts on the growing fetus. The current research evaluated the effects of prenatal methamphetamine exposure on helping behaviour and neuroinflammatory cascade in the amygdala of male offspring.

Emotional contagion occurs in many animals, including rodents. To determine the social signals of emotional state-matching between individuals in mice, we conducted an empirical laboratory experiment using visual, olfactory and auditory stimuli. The Japanese wild-derived mouse strain MSM/Ms (MSM) was tested as observers, since our initial experiments indicated that MSM mice showed higher sensitivity to others' pain compared with the laboratory strain C57BL/6J (B6).

Empathy, characterized by the ability to recognize and share the emotions of others, plays a fundamental role in shaping social interactions. It allows individuals to respond to the emotional states of others, promoting prosocial behaviors and social bonding. Observational fear is a fundamental aspect of affective empathy, where an observer witnesses a demonstrator undergoing aversive experiences and subsequently exhibits fear behaviors.

Artificial intelligence-based clinical decision support systems have a potential to improve clinical practice, but they may have a negative impact on the physician-patient dialogue, because of the control problem. Physician-patient dialogue depends on human qualities such as compassion, trust, and empathy, which are shared by both parties. These qualities are necessary for the parties to reach a shared understanding -the merging of horizons- about clinical decisions.
