Learning modifies odor mixture processing to improve detection of relevant components
Honey bees have arich repertoireofolfactory learning behaviors, and they therefore arean excellent modelto study plasticity in olfactory circuits. Recent behavioral, physiological, and molecular evidence suggested that the antennal lobe, the first relay of the olfactory system in insects and analog...
