“…The lines were named Roman Low Avoidance (RLA: low rates of two-way avoidance; i.e., high anxiety-related response) and Roman High Avoidance (RHA: high rates of twoway avoidance; i.e., low anxiety-related response). In 1964, these two were transferred to England, from which they were distributed to various laboratories [35]. One of the most well-known colonies was established in 1972 at the Institut für Verhaltenswissenschaft, Zürich, Switzerland.…”

evaluation of eight rat lines selected for high and low anxiety-related responses" (2013 • Genetic models are powerful tools to help understand anxiety disorders.• In order to determine the extent to which multiple anxiety traits generalize we compared eight genetic lines of rats selected for single high or low emotional responses.• We find many behavioral traits generalize across different animal lines selected for a single trait. a b s t r a c t Anxiety traits can be stable and permanent characteristics of an individual across time that is less susceptible of influences by a particular situation. One way to study trait anxiety in an experimental context is through the use of rat lines, selected according to contrasting phenotypes of fear and anxiety. It is not clear whether the behavioral differences between two contrasting rat lines in one given anxiety test are also present in others paradigms of state anxiety. Here, we examine the extent to which multiple anxiety traits generalize across selected animal lines originally selected for a single anxiety trait. We review the behavioral results available in the literature of eight rat genetic models of trait anxiety -namely Maudsley Reactive and Non-reactive rats, Floripa H and L rats, Tsukuba High and Low Emotional rats, High and Low Anxiety-related rats, High and Low Ultrasonic Vocalization rats, Roman High and Low Avoidance rats, Syracuse High and Low Avoidance rats, and Carioca High and Low Conditioned Freezing rats -across 11 behavioral paradigms of innate anxiety or aversive learning frequently used in the experimental setting. We observed both convergence and divergence of behavioral responses in these selected lines across the 11 paradigms. We find that predisposition for specific anxiety traits will usually be generalized to other anxiety provoking stimuli. However this generalization is not observed across all genetic models indicating some unique trait and state interactions. Genetic models of enhanced-anxiety related responses are beginning to help define how anxiety can manifest differently depending on the underlying traits and the current environmentally induced state. a r t i c l e i n f o

“…Two phenotypes with different emotional and motivational profiles have been developed through bidirectional selection and breeding of the Roman high-(RHA) and low-avoidance (RLA) rat lines/ strains (outbred or inbred, respectively), selected for rapid (RHA) vs extremely poor (RLA) acquisition of two-way active avoidance in the shuttle-box (Broadhurst and Bignami, 1965;Driscoll and Bättig, 1982) (for reviews, see Driscoll et al, 1990Driscoll et al, , 1998Driscoll et al, , 2009Escorihuela et al, 1995Escorihuela et al, , 1999Fernández-Teruel et al, 1997;Giorgi et al, 2007;Steimer and Driscoll, 2005). These lines/strains show consistent differences in sensation/novelty seeking and in stress/anxiety endocrine and behavioral responses when confronted with novel environments (ie, intended to measure anxiety, emotionality, fearfulness, or novelty seeking), such as the open-field test (Aubry et al, 1995;Carrasco et al, 2008;Escorihuela et al, 1999;Gentsch et al, 1991), elevated plus maze (Escorihuela et al, 1999;Steimer and Driscoll, 2003), elevated zero-maze (López-Aumatell et al, 2009b), blackwhite box test, dark-light open-field test, dark-light hexagonal tunnel maze (Fernández-Teruel et al, 2002b;Steimer and Driscoll, 2005), and hole-board test (Escorihuela et al, 1999;Fernández-Teruel et al, 1992).…”

The selective breeding of Roman high-(RHA) and low-avoidance (RLA) rats for rapid vs extremely poor acquisition of active avoidance behavior in a shuttle-box has generated two phenotypes with different emotional and motivational profiles. The phenotypic traits of the Roman rat lines/strains (outbred or inbred, respectively) include differences in sensation/novelty seeking, anxiety/fearfulness, stress responsivity, and susceptibility to addictive substances. We designed this study to characterize differences between the inbred RHA-I and RLA-I strains in the impulsivity trait by evaluating different aspects of the multifaceted nature of impulsive behaviors using two different models of impulsivity, the delay-discounting task and five-choice serial reaction time (5-CSRT) task. Previously, rats were evaluated on a schedule-induced polydipsia (SIP) task that has been suggested as a model of obsessive-compulsive disorder. RHA-I rats showed an increased acquisition of the SIP task, higher choice impulsivity in the delay-discounting task, and poor inhibitory control as shown by increased premature responses in the 5-CSRT task. Therefore, RHA-I rats manifested an increased impulsivity phenotype compared with RLA-I rats. Moreover, these differences in impulsivity were associated with basal neurochemical differences in striatum and nucleus accumbens monoamines found between the two strains. These findings characterize the Roman rat strains as a valid model for studying the different aspects of impulsive behavior and for analyzing the mechanisms involved in individual predisposition to impulsivity and its related psychopathologies.

The selective breeding of Roman high-(RHA) and low-avoidance (RLA) rats for, respectively, rapid vs extremely poor acquisition of avoidant behavior in a shuttlebox has produced two phenotypes that differ in temperament traits, in mesocortical/mesolimbic dopamine system function, and in the behavioral and neurochemical responses to the acute and repeated administration of psychostimulants and opiates. The phenotypic traits of the RHA line predict higher susceptibility, compared with RLA rats, to the reinforcing properties of addictive substances like cocaine. The present study was designed to compare the acquisition, maintenance, reinstatement of drugseeking after long-term extinction, and reacquisition of intravenous cocaine self-administration (SA) behavior in the Roman lines. Compared with RLA rats, the rates of responding during cocaine SA acquisition were higher, extinction from cocaine SA was prolonged, and drug-induced reinstatement of cocaine-seeking behavior was more robust in RHA rats. Moreover, only RHA rats reacquired extinguished lever-pressing activity when a low reinforcing dose of cocaine was available. These findings are consistent with the view that subjects with genetically determined high responsiveness to the acute and chronic (ie, sensitizing) effects of psychostimulants, such as RHA rats, also display a higher propensity to self -administer cocaine. Further comparative studies in the Roman lines, using SA paradigms that distinguish mere drug-taking from the compulsive and uncontrolled drug use that characterizes addiction in humans, may eventually help to characterize the relationships among genotype, temperament traits, and neurobiological mechanisms involved in the individual vulnerability to cocaine addiction.
