Neuron of a Roundworm

Caption

This image shows a single sensory neuron in the roundworm Caenorhabditis elegans. Salk researchers demonstrated how a neural circuit uses prior experience to modify future behaviors. The work reveals new details on the function of two chemical signals critical to animal-and human-behavior: dopamine (responsible for reward and risk-taking) and CREB (needed for learning).
