Uncertainty Monitoring in Sprague-Dawley Rats (Rattus norvegicus)
… Smith & Schull, 1989). In the current study, two Sprague-Dawley rats were tested in a tone-length discrimination task in which they were prompted to press one of two levers indicating "short" or "long" depending on the duration of a tone. They also had the option to opt out of some trials. If the …

Thymoquinone decreases oxidative DNA damage (8-OHdG) in DMBA treated female Sprague Dawley rats
… 8-OHdG and GSH compared with tamoxifen in female Sprague Dawley rats treated with 7,12 dimethylbenz (a)anthracene (DMBA, a drug that induces mammary cancer). 8-OHdG is the most commonly assayed fingerprint of free radical attack on DNA and is involved in tumor progression. Five groups of 10 rats …
