BOS-CON neurons generally respond to more stimuli than CON-ONLY neurons. A: BOS-CON cells tended to respond to multiple CON stimuli. The distribution of all recorded BOS-CON neurons shows the tendency for these cells to exhibit excitatory responses to multiple CON stimuli. Note that the mode of the distribution is 10, indicating that most BOS-CON cells responded to all conspecific stimuli in addition to BOS. This feature strongly distinguished them from BOS-ONLY cells, which showed excitatory responses only to BOS. B: CON-ONLY cells responded to fewer CON stimuli, on average, than BOS-CON cells. Note that the mode of the distribution is 1, which is markedly different from the distribution of BOS-CON cells.
