Memory traces: snails reveal a novel storage mechanism.
A new study of memory traces in an invertebrate challenges convention in two ways: first, by demonstrating a persistent change in synaptic strength that is maintained remotely, via the passive spread of somatic depolarization; and second, by localizing a critical memory trace to neurons located outside the behavioral circuit affected by learning.
