Exerting self-control for persistence.

摘要

Synapses made by a neuron onto itself- known as autapses - have been described in various brain regions, including the neocortex, hippocampus, cerebellum, substantia nigra and striatum, but their purpose has remained uncertain. Reporting in Current Biology, Susswein and colleagues show that autaptic transmission in Aplysia B31/B32 neurons of the buccal ganglia is involved in the long-lasting response to brief stimulation.
