Olfactory generalization.

<p>A) The lateral horn neuron (LHN) responds to rewarded stimuli (CS) and two novel odorants with different level of the similarity to the CS (A’ is more similar to A than A”) after training to CS. LHN’s response to the A’ exhibits more perceptually similar to the CS for bees than to A”. B) The colour matrix shows the olfactory generalization matrix which represents the LHN response to six odours in the tests performed by bees trained with different CSs. Colour pixels (<i>i</i>,<i>j</i>) indicate the firing rate of LHN for the <i>j</i>th odour when the model was trained by the <i>i</i>th odours. The results show asymmetric generalization between odours.
