From: Heterosynaptic plasticity-induced modulation of synapses
The effect of spatial distribution and sign of homosynaptic plasticity on the direction of synaptic plasticity. A Inducing LTP at a fraction of synapses was associated with a weaker heterosynaptic LTP at adjacent distances and heterosynaptic LTD at more distant inputs. B Heterosynaptic plasticity with the same homosynaptic plasticity is induced at short distances, while those of opposite signs have been induced further away from the focus of activation
