Understanding the neural systems underlying the controls of energy balance has been greatly advanced by identifying the deficits and underlying mechanisms in rodent obesity models. n. 1. a. The LONG EVANS rat is the result of a cross between a female albino from the WISTAR Institute and a wild male (Rattus norvegicus) captured near Berkeley and offspring selection. The Long Evans rat is commonly used in alcohol research because this strain drinks alcohol at a higher rate than many other strains (e.g., Wistar or Sprague-Dawley). The LongEvans rat is an outbred rat developed by Drs. Long and Evans in 1915 by crossing several Wistar females with a wild gray male.

M. Martnez-mateos. It is an albino strain, easy-to-handle, it is however slower learner than Long Evans rat. To develop a pre-clinical animal model to investigate this, the present study examined sex differences in sucrose taking and seeking using Long-Evans rats.
This model was developed by Dr Long and Dr Evans in 1915. Long Evans rats required fewer sessions than Sprague Dawley rats to learn operant tasks, including a signal detection task and reversal learning. The number and weight ot the ietus, the weaning time weight per cote and per litter in the second litter were the highest, and the fifth litter was the lowest.
