Telencephalic expression of homer1a induced by exposure to water or Ensure cues. (A) Pseudocolor autoradiographic phosphorescence images of coronal brain sections hybridized with a probe for homer1a 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 homer1a in telencephalic regions. Ensure cues increased the expression of homer1a in a many of the corticolimbic regions examined (*p < 0.05). For abbreviations, see legend to Figure 1.
