Unitary PSCs are not detectably different between day and night. A, Example responses obtained from one cell during the day (left) and another cell at night (right). Individual trials are in gray and the averages of successes, excluding failures, are in black. PSCs were obtained at standard power (top, 100 μW) and at a threshold power (bottom) with >60% response failures. With this paradigm, IPSCs were assumed to be primarily unitary; originating from single presynaptic VIP+ neurons. B, Average success amplitude obtained at threshold power. Each point is the average from a single neuron. C, The ratio of standard/threshold amplitudes for data plotted in B.
