Electrical stimulation produces feelings of free will : Not Exactly Rocket Science
Nerves in the limb send messages back to your brain, but the subjective experience you have of stretching isn't due to these signals. The feeling that you willed your arm into motion, and the realisation that you moved it at all, are both the result of an area at the back of your brain called the posterior parietal cortex. This region helped to produce the intention to move, and predicted what the movement would feel like, all before you twitched a single muscle.

Magic and the Brain: Teller Reveals the Neuroscience of Illusion
Now that on-the-job experimentation has taken an academic turn. A couple of years ago, Teller joined a coterie of illusionists and tricksters recruited by Stephen Macknik and Susana Martinez-Conde, researchers at the Barrow Neurological Institute in Phoenix, Arizona, to look at the neuroscience of magic. Last summer, that work culminated in an article for the journal Nature Reviews Neuroscience called "Attention and Awareness in Stage Magic." Teller was one of the coauthors, and its publication was a signal event in a field some researchers are calling magicology, the mining of stage illusions for insights into brain function.

Voodoo Correlations: Have the Results of Some Brain Scanning Experiments Been Overstated?: Scientific American
VUL: We use that term as a humorous way to describe mysteriously high correlations produced by complicated statistical methods (which usually were never clearly described in the scientific papers we examined)—and which turn out unfortunately to yield some very misleading results. The specific issue we focus on, which is responsible for a great many mysterious correlations, is something we call “non-independent” testing and measurement of correlations. Basically, this involves inadvertently cherry-picking data and it results in inflated estimates of correlations.

In 1953, radical brain surgery was used on a patient with severe epilepsy. The operation on "H.M." worked, but left him with almost no long-term memory. H.M. is now in his 80s. His case has helped scientists understand much more about the brain.
