Suppose cells A and B, both of which release inhibitory transmitter, are endogenously tonically active, and the inhibitory effect produced by either one of the cells on the other persists for 1/2 sec after the presynaptic cell has stopped firing. Which of the following patterns of activity is produced by this 2-neuron circuit that is reminiscent of the 3-neuron ring oscillator discussed in the lab manual? [Hint: This question becomes much easier if you look carefully to see whether any aspect of the activity patterns below conflicts with any of the rules given in the question. For example: In (a), at the very start of the traces, cell A stops firing as soon as cell B starts. Is this consistent with the rules? For another example: In (a), early in the traces, cell B starts firing as soon as cell A stops. Is this consistent with the rules?
