kandel150.jpg This year’s annual question at Edge was, “What are you optimistic about?”. Now, Brockman has asked Eric Kandel to outline the four neuroscience breakthroughs made in 2006 that makes him optimistic about our future possibility of understanding the brain. The first breakthrough is research into the role of microRNAs in the formation of synapses. The second is research into the encoding of external space in the hippocampus and the entorhinal cortex. Kandel’s third choice is research into social interaction, including Rebecca Saxe’s imaging studies of Theory of Mind, and Barry Dickson’s discovery that if the male form of the protein fruitless is expressed in female Drosophila, the females will display male courship behaviour. And his fourth is the possibility, through neuroimaging and other new techniques, of understanding the effects of psychotherapy on psychiatric diseases.

All four advances are clearly great causes for optimism. But maybe there are other breakthroughs worth mentioning? What about research into decision-making, or comparative genetic studies casting light on the evolution of the hominid brain? I bet that you readers have your own suggestions. Please share them with us in the comments section.
