Reviews
The neuronal background K2P channels: focus on TREK1
Eric Honoré
p251 | doi:10.1038/nrn2117
TREK1 is the most extensively studied of the mammalian two-pore-forming K+ channels and is widely expressed in the brain. Honoré reviews the functional properties of TREK1 and describes recent results indicating its important roles in CNS function and disease.
Molecular mechanisms of memory reconsolidation
Natalie C. Tronson & Jane R. Taylor
p262 | doi:10.1038/nrn2090
Memory reconsolidation theory is the subject of intensive recent research and debate. Tronson and Taylor outline the molecular events implicated in this process and discuss how elucidating its mechanisms could improve our understanding of normal and abnormal memory function.
The machinery of colour vision
Samuel G. Solomon & Peter Lennie
p276 | doi:10.1038/nrn2094
The basic principles of colour vision have been understood for a long time, but recent studies have revealed the processes underlying it in more detail. Lennie and Solomon review our current understanding of colour processing, from cones to the primary visual cortex.
Agenesis of the corpus callosum: genetic, developmental and functional aspects of connectivity
Lynn K. Paul, Warren S. Brown, Ralph Adolphs, J. Michael Tyszka, Linda J. Richards, Pratik Mukherjee & Elliott H. Sherr
p287 | doi:10.1038/nrn2107
Agenesis of the corpus callosum (AgCC) shares anatomical and behavioural features with certain neurodevelopmental and psychiatric disorders. Providing insight into the developmental and molecular basis of AgCC, Lynn Paul and colleagues explain why AgCC may be a good model for other brain disorders.
The neurobiology of punishment
Ben Seymour, Tania Singer & Ray Dolan
p300 | doi:10.1038/nrn2119
Humans punish selfishly but also altruistically. Seymour, Singer and Dolan propose a neurobiological model of punishment based on our understanding of motivational systems, observational studies that show how punishment mediates cooperation, and brain imaging data from humans playing economic games.

Repair of neural pathways by olfactory ensheathing cells
Geoffrey Raisman & Ying Li
p312 | doi:10.1038/nrn2099
Loss of aligned glial pathways may contribute to the inability of axons to successfully regenerate following CNS injury. Raisman and Li discuss why transplantation of olfactory ensheathing cells might be a promising strategy to re-establish these pathways and restore function.
