Neuroscience Variation on Synaptic Potentiation

Peter Stern

Science, AAAS, Cambridge CB2 1LQ, UK

Synaptic changes linked to associative learning are well known. Lamsa et al. examined long-term synaptic plasticity in different types of interneurons in rat hippocampal slices. They discovered an induction rule for long-term potentiation (LTP) that shows unusual characteristics. In contrast to known forms of plasticity, pairing synaptic input with hyperpolarization resulted in LTP, whereas pairing it with depolarization prevented it.
