Abstract
Three dimensional activity surfaces and flat activity contour maps were plotted for groups of need-free (nondeprived) rats in 4 areas of gustatory stimulation. Each area is defined by concentrations of 2 solutes in compound solution. Every compound solution contained sucrose plus 1 of the following: sodium chloride, quinine hydro chloride, tartaric acid, sodium saccharin. The activity maps show mean rates of licking (licks/min recorded electrically) and how these rates depend upon variations in compound stimulus. Analysis of data in relation isohedonic contour maps shows that preferences cannot be reliably predicted from rates of licking (rates of ingestion) nor can rates of licking be reliably predicted from isohedons.
