One click, two clicks: the past shapes the future in auditory cortex.
What are the synaptic and cellular mechanisms by which stimulus context shapes cortical responses? In this issue of Neuron, Wehr and Zador describe intracellular recordings of responses to click pairs in rat primary auditory cortex (A1) and offer new insights into the successive roles of inhibition and synaptic depression in suppressing responses to the second click in many A1 neurons.
