2020

The Thiele Lab publishes a manuscript titled “Distinct and Overlapping Patterns of Acute Ethanol-Induced C-Fos Activation in Two Inbred Replicate Lines of Mice Selected for Drinking to High Blood Ethanol Concentrations” in the journal, Brain Sciences.

Drs. Stacey L Robinson and Ana Paula S. Dornellas co-first authored a paper that assessed ethanol-induced neuronal activation in selectively bred iHDID-1 and iHDID-2 mouse lines relative to a control line of mice. While both the iHDID-1 and iHDID-2 lines show high levels of ethanol consumption, the pattern of ethanol-induced c-Fos activation differed between the lines in many cases, suggesting that the iHDID1 and the iHDID2 lines arrived at a similar behavior phenotype through divergent genetic mechanisms. These finding are published in Brain Sciences.
