We are pleased to announce a sixth meeting on Synapses: From Molecules to Circuits & Behavior, which will be held at Cold Spring Harbor Laboratory, New York. The meeting will begin at 7:30pm on Tuesday, April 16, and will conclude with lunch on Saturday, April 20, 2013. The proposed meeting will assemble the leaders in the field, together with junior faculty, postdoctoral fellows and graduate students, to discuss new, cutting-edge developments in the molecular control of neuronal excitability and synapse function.
