How do the mitral cells in the olfactory bulb of zebrafish integrate the different sets of odorant receptor information that they receive from different dendritic branches? Yoshihara and colleagues in their Perspective discuss the possibility that fish mitral cells slowly switch the inflow of input signals from one dendrite to another and thus transmit different receptor signals at different times to the olfactory cortex (Friedrich and Laurent).
