Figure 5. Positive control for the effect of CCh.

Figure 5

The graphs show the average percent investigation time as compared to the first habituation trial. Saline infused control rats respond significantly more to C2 (two carbon difference to habituation odor) than to the last habituation trial. In contrast, CCh infused rats respond significantly more to both C1 (one carbon difference to habituation odor) and C2. These data compare to those previously obtained with neostigmine (Chaudhury et al., 2009) and show that the dosage of CCh used here is effective in the OB. Asterisks indicate a significant increase in response level compared to the last habituation trial.
