Accessory olfactory learning.

Learning in the accessory olfactory bulb is modelled mathematically by means of a set of coupled oscillator equations to describe the ongoing activity. The modification of this activity by experience is shown to lead to a change of the transfer function of the AOB as an input-output device. This leads both to a test of the model and a means of discovering how the later stages of the brain may use the AOB output. Our discussion is limited to a specific form of learning in the mouse, but may have more general applicability.
