Fear is an intrinsic part of human and animal evolution, but it can manifest itself in pathological ways, such as Anxiety Disorder. There are studies in the literature that point to the use of animal models to understand psychopathologies, due to their simplicity and neurobiological similarity. Two strains of rats were developed, called Cariocas with High and Low Freezing (CAC and CBC), which means anxiety levels. The objective of this study was to investigate compulsive and hyperactive behaviors in Cariocas, specifically the grooming and rearing of 138 animals (CAC, n=34; CBC, n=36; CTL, n=38). The methodology was analytical and descriptive based on images obtained from recordings of the contextual fear test, over 8 minutes before the shock. Our results indicated that BCC present a higher frequency [F(3,60)= 45.94, p<0.0001] and duration [F(3,43)= 21.51, p< 0.0001] of behavior rearing when compared to the other groups, CAC and CTL (rANOVA; P<0.05, LSD post hoc test). Likewise, regarding grooming, there was a significant decrease in total time [F(2.00)= 6.35, p<0.01]. Therefore, the results suggest that CBCs exhibit more hyperactive behavior, supporting the hypothesis that they may serve as an animal model of ADHD.
