I am a huge fan of neuroscientist Jonah Lehrer. He seems impossibly young for someone that has studied and published so much already. I devoured his books Proust Was A Neuroscientist, How We Decide and have already gotten halfway through the just published Imagine: How Creativity Works. His Wired blog Frontal Cortex is also a must read for anyone interested in the brain. Besides his obvious intelligence Lehrer has the talent to understand and convey deeply complex science in narratives that are engaging and thought-provoking without diminishing the power of his research. Highly recommend you take a look at his books.
