The microstructure of the ingestive behavior of rats ingesting corn oil emulsions was analyzed to describe quantitatively how postingestional stimulation interacts with orosensory stimulation to control the intake of corn oil. Seventeen hour food deprived rats were given 30-min access intake tests with corn oil emulsions ranging in concentration from 0.125%(More)
To determine if oropharyngeal stimulation contributes to the magnitude of the negative feedback signal during ingestion, we tested rats on a series of solutions that varied in taste intensity but not in nutritive or osmotic properties. To do this, Na saccharin was added to a standard 0.2 M glucose solution in concentrations of 0, 0.25, 0.5, 1, 2, 4, and 8(More)
