●Nucleus hears axon's pain. Blesch, A. & Tuszynski, M. H. Nature Medicine March (2004) This News and Views article highlights new findings on the molecular mechanism that enables the axon to communicate with the cell body after axonal injury.

●Trafficking in cell fate. Bajjalieh, S. Nature Genetics March (2004) The hyh mutation underlies a form of congenital hydrocephalus, and this News and Views article reports that it has been traced to the gene that encodes the membrane-trafficking protein αSnap. The mutation causes mis-sorting of apical proteins and precocious neurogenesis.

●Fantastic pheromones. Mombaerts, P. Nature Neuroscience March (2004) Mombaerts reviews two new books on pheromones — Pheromones and Animal Behaviour: Communication by Smell and Taste by Tristram D. Wyatt, and Vomeronasal Chemoreception in Vertebrates: a Study of the Second Nose by Charles Evans.

●Prefrontal responses to drug cues: a neurocognitive analysis. Wilson, S. J. et al. Nature Neuroscience March (2004) This Perspective article reviews neuroimaging studies that provide important insights into the brain systems that are involved in cue-elicited craving.

●Just one word: plasticity. Blight, A. B. Nature Neuroscience March (2004) In this News and Views article, Blight reports on a new study that shows that spontaneous recovery of function after corticospinal tract injury involves extensive plastic changes in the connectivity of numerous types of neurons that are distributed throughout the central nervous system.

●The Prozac pipeline. Meltzer, H. Y. Nature Medicine March (2004) Meltzer reviews the book Better than Prozac: Creating the Next Generation of Psychiatric Drugs by Samuel H. Barondes.

●Sox3 and sexual dysfunction: it's all in the head. Camper, S. A. Nature Genetics March (2004)

●When music tells a story. Janata, P. Nature Neuroscience March (2004) People commonly attribute semantic meaning to musical passages, but there have been few scientific studies of this process. In this News and Views article, Janata discusses new evidence that excerpts of classical music can cause behavioural and electrophysiological priming effects that are indistinguishable from those evoked by sentences.

●Manipulating your mind. Breithaupt, H. & Weigmann, K. EMBO Reports March (2004) In this Analysis article, the authors ask: what will science discover about our brains, and how are we going to deal with it?
