(B) Cumulative histogram of the memory performance. Memory performance is indicated as a stepped line. The sigmoidal fit is indicated as a continuous line. The predicted rescue on the basis of the extent of transgenic GFPGluR-B expression (Figure 5D) and the correlation between memory and GluR-B levels in piriform cortex (9.1 ± 2.5% increase in memory for 10% increase in protein, Figure 4D) is shown in blue. Note that the predicted rescue is in perfect numerical correspondence to the memory performance of GluR-BRescue mice.
