Isolation-induced ultrasonic vocalizations in pups: A comparison between Long-Evans, Sprague-Dawley, and Wistar rats.
Schwarting RKW and Wöhr M. Dev Psychobiol 2018. PMID 29797318
Rat pup ultrasonic vocalizations (USV) are usually studied in outbred rats belonging to either Long-Evans, Sprague-Dawley, or Wistar stocks, but these were not compared so far. ...

Comprehensive behavioural analysis of Long Evans and Sprague-Dawley rats reveals differential effects of housing conditions on tests relevant to neuropsychiatric disorders.
Turner KM and Burne TH. PLoS One 2014. PMID 24671152 Free PMC article.
Long Evans rats required fewer sessions than Sprague Dawley rats to learn operant tasks, including a signal detection task and reversal learning. Furthermore, Long Evans rats housed in enriched cages acquired simple operant tasks faster than standard housed Long Evans rats. ...

Sex differences in alcohol self-administration and relapse-like behavior in Long-Evans rats.
Randall PA, et al. Pharmacol Biochem Behav 2017. PMID 28347737 Free PMC article.
The current experiments sought to decrease this gap in our understanding of sex differences in alcohol use disorders by assessing both male and female Long-Evans rats in parallel on alcohol self-administration, relapse-like behavior following abstinence and extinction, and motivation to respond for the standard alcohol solution and a quinine-adulterated alcohol solution. ...Further, the consistent patterns of responding across months of self-administration training in both males and females, lend support for the feasibility of conducting these studies in male and female rats in parallel without concerns about daily variability. ...

Sex differences in juvenile play behavior differ among rat strains
Northcutt KV and Nwankwo VC. Dev Psychobiol 2018. PMID 29969514
In this experiment, we tested play and defensive behaviors in male and female Long-Evans, Sprague-Dawley, and Wistar rats. When observed with a cage mate during the juvenile period, Long-Evans rats played more than Wistar animals, but there were no sex differences in any strain. When tested with an unfamiliar sibling (not seen since weaning), both Long-Evans and Wistar rats played more than Sprague-Dawley animals, and Long-Evans females played more than males. ...

Working-memory training: effects on delay discounting in male Long Evans rats.
Renda CR, et al. J Exp Anal Behav 2015. PMID 25418508 Free PMC article.
., substance dependence, gambling) and some evidence suggests steep discounting precedes and predicts drug-taking in humans and rats, this study sought to experimentally reduce rats' delay discounting. ...To evaluate the cross-species generality of this effect, 38 male Long-Evans rats, matched on pretraining delay-discounting rates, were randomly assigned to receive 140 sessions of working-memory training or sham training (which required no memory of the sample stimulus). ...

Long-Evans rats have a larger cortical topographic representation of movement than Fischer-344 rats: a microstimulation study of motor cortex in naïve and skilled reaching-trained rats.
VandenBerg PM, et al. Brain Res Bull 2002. PMID 12431749
The effect of cortical stimulation was compared in young male Long-Evans rats and Fischer-344 rats. The overall size of the motor cortex representation was greater in Long-Evans rats compared to Fischer-344 rats and the threshold required to elicit a movement was higher in the Fischer-344 rats. ...The Long-Evans rats were quantitatively and qualitatively better in skilled reaching than the Fischer-344 rats. Also, Long-Evans rats exhibited a relatively larger area of the topographic representation and lower thresholds for eliciting movement in the contralateral forelimb. ...

Long-Evans and Sprague-Dawley rats have similar skilled reaching success and limb representations in motor cortex but different movements: some cautionary insights into the selection of rat strains for neurobiological motor research.
Whishaw IQ, et al. Behav Brain Res 2003. PMID 14529819
The most widely used strain for studies of the neural basis of movement is the out bred, pigmented Long-Evans strain, while the most widely used strains for the study of movement impairments in neurological disease are out bred albino rats, including Sprague-Dawley rats. ...Long-Evans and Sprague-Dawley rats did differ in the movements used for reaching and on the quality of their movements. The movements of Sprague-Dawley rats resembled the movements of Long-Evans rats with motor system injury. ...

Is the consonant bias specifically human? Long-Evans rats encode vowels better than consonants in words.
Bouchon C and Toro JM. Anim Cogn 2019. PMID 31222546
The current study investigated this issue in a species phylogenetically distant from humans: Long-Evans rats. During training, the animals were presented with four natural word-forms (e.g., mano, "hand"). ...Together with previous findings in very young human infants, this reliance on vocalic information we observe in rats suggests that the emergence of the consonant bias may require a combination of vocal, cognitive and auditory skills that rodents do not seem to possess....

Rats engage in suboptimal choice when the delay to food is sufficiently long.
Cunningham PJ and Shahan TA. J Exp Psychol Anim Learn Cogn 2019. PMID 31070433
Numerous examples in the decision-making literature demonstrate that animals sometimes make choices that are not in their long-term best interest. ...The present experiment explored the possibility that rats will engage in suboptimal choice if the delay to food at the choice point is sufficiently long, as the temporal information-theoretic model suggests. ...

Motion perception in rats (Rattus norvegicus sp.): deficits in albino Wistar rats compared to pigmented Long-Evans rats.
Hupfeld D and Hoffmann KP. Behav Brain Res 2006. PMID 16563528
Motion perception was tested in pigmented Long-Evans and albino Wistar rats (Rattus norvegicus sp.) using moving random dot patterns. ...These results indicate that pigmented rats have well developed motion coherence perception, whereas albino rats are severely impaired but not motion blind....
