Dopamine Neurons Mediate Learning and Forgetting through Bidirectional Modulation of a Memory Trace (Cell Reports)

In Drosophila, dopamine neurons regulate both learning and forgetting. Berry et al. identify a locus for the storage and retrieval of a short-term memory trace and show that a single dopamine neuron regulates both formation and disruption of this trace. These findings elucidate circuit mechanisms underlying memory storage and removal.
