Telencephalic expression of zif268 induced by exposure to water or Ensure cues. (A) Pseudocolor autoradiographic phosphorescence images of coronal brain sections hybridized with a probe for zif268 from a rat in the water cues group (top) and the Ensure cues group (bottom). (B) Graphical representation of semiquantitative measurements of in situ hybridization for zif268 in telencephalic regions. Ensure cues increased the expression of zif268 in a many of the corticolimbic regions examined (*p < 0.05). For abbreviations, see legend to Figure 1.
