Figure 6.

Averaged changes of the oscillatory rhythm recorded in vitro in the procerebrum of snails trained to respond with feeding reaction to odor application. (A) Changes in amplitude of the procerebral oscillations in response to cineole application in 5% (n = 6) and (B) 20% (n = 5) concentrations. (C) Changes in frequency of the procerebral oscillations in response to cineole application in 5% (n = 6) and (D) 20% (n = 5) concentrations. Vertical bars indicate the standard error of the mean. * p < 0.05, ** p < 0.01, *** p < 0.001. (E,F) The response of the procerebrum, MtC3, MtC1 neurons and the cerebro-buccal connective to cineole 5% (E) and 20% (F) application to the nose–brain preparation of the snail trained to respond with the feeding reaction to the cineole.
