text: First, following  we assumed here that the triggering of a learning event in a dendrite, which induces both LTP and LTD, depends on a compound threshold: in order to learn, a dendrite must both (1) receive an unusually strong presynaptic input, that is, unusually many axons impinging on the dendrite must be firing and releasing glutamate; and (2) experience an unusually strong post-synaptic response, that is, unusually many of the firing axons must be driving synapses that are already in a strong state.
