R programming has three ways of assigning values to a variable. They are =, <-, and the assign function. The assign function has the basic format of assign(“variable”, value) where “variable” is the name of the variable receiving the values, note that it needs to be in quotes, an...
In rodent models, studies have been able to manipulate this critical organizational window to mechanistically examine its importance in sex differences in long-term stress programming. For instance, adult sex differences in hippo- campal expression of the glucocorticoid receptor, critical for the ...
