Behavioral mirroring in Wistar rats investigated through temporal pattern analysis.

The study of social interactions lies at the core of several disciplines such as psychiatry, psychology and ethology, just to name a few. In this context, understanding the temporal patterns underlying interactive behaviors is of crucial importance. Here, we employed T-pattern detection and analysis to study social interactions in ten pairs of Wistar rats tested in an Open-Field environment.

Physiology, patterns and behavior.

This article endeavors to provide a useful perspective for Researchers and Authors within the realm of Behavioral Sciences, particularly those engaged in the study of Behavioral Physiology, namely the discipline focusing on the intricate interplay between physiological processes and the related behavioral manifestations. Alongside the prevailing conservatism that has characterized the progression of behavioral sciences in recent decades, it advocates for an additional approach in the study of Behavioral Physiology that revolves around a more inclusive perspective: beyond the analysis of isolated behavioral events as discrete components, akin to scattered pieces of a larger puzzle, emphasis also is placed on elucidating their interconnectedness. It is within these interrelationships that the governing constraints of behavior, whether exhibited by humans or any other species, manifest as a cohesive and functional structure.

Sex-dependent behavioral effects of chronic nicotine during adolescence evaluated in young adult rats tested in Hole-Board.

As one of the leading causes of death and serious illnesses, tobacco smoking remains a significant issue in modern societies. Many individuals smoke during adolescence, a trend that has been exacerbated by the prevalence of vaping among young people. In this context, studying the behavioral effects induced by nicotine administration in male and female rats, during the adolescent period, assumes great importance because it can help to better understand the dynamics underlying tobacco use in the two sexes.

The hole-board apparatus in the study of anxiety.

Anxiety disorders pose a significant challenge in contemporary society, and their impact in terms of social and economic burden is overwhelming. Behavioral research conducted on animal subjects is crucial for comprehending these disorders and, from a translational standpoint, for introducing innovative therapeutic approaches. In this context, the Hole-Board apparatus has emerged as a widely utilized test for studying anxiety-related behaviors in rodents.

A quantitative and T-pattern analysis of anxiety-like behavior in male GAERS, NEC, and Wistar rats bred under the same conditions, against a commercially available Wistar control group in the hole board and elevated plus maze tests.

Aim: The Genetic Absence Epilepsy Rats from Strasbourg (GAERS) are an inbred polygenic model of childhood absence epilepsy (CAE), which, as their non-epileptic control (NEC) rats, are derived from Wistar rats. While the validity of GAERS in reproducing absence seizures is well established, its use as a model for CAE psychiatric comorbidities has been subject to conflicting findings. Differences in colonies, experimental procedures, and the use of diverse controls from different breeders may account for these disparities.
