Neuronal development: specifying a hard-wired circuit.
The formation of neuronal circuits that relay distinct olfactory information is thought to depend on cues provided by pre-synaptic receptor neurons. But direct visualization of second order neurons in Drosophila now suggests that dendritic targeting occurs independently of interactions with incoming sensory neurons.
