Abstract:
Recent experimental results on spike-timing-dependent plasticity (STDP) and heterosynaptic interaction in various systems have revealed new temporal and spatial properties of activity-dependent synaptic plasticity. These results challenge the conventional understanding of Hebb's rule and raise intriguing questions regarding the fundamental processes of cellular signaling. In this article, I review these new findings that lead to formulation of a new set of cellular rules. Emphasis is on evaluating potential molecular and cellular mechanisms that may underlie the spike-timing window of STDP and different patterns of heterosynaptic modifications. I also highlight several unresolved issues, and suggest future lines of research.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
