Excerpts taken from a website (

You'll likely need to dig to get access to the real paper, otherwise you need to pay to read it on an actual scientific journal site that features published work. However, this website covers the findings and provides sources. This is not a dead topic and is hotly debated of course. You can find plenty of people arguing for and against it.
"For example,
a study by John-Dylan Haynes in 2008 showed a similar effect to the one revealed by Libet. After putting participants into an fMRI scanner, he told them to press a button with either their right or left index fingers at their leisure, but that they had to remember the letter that was showing on the screen at the precise moment they were committed to their movement.
The results were shocking. Haynes's data showed that the BP occurred one entire second prior to conscious awareness —
and at other times as much as ten seconds. Following the publication of his paper,
he told Nature News:
The first thought we had was 'we have to check if this is real.' We came up with more sanity checks than I've ever seen in any other study before.
The cognitive delay, he argued, was likely due to the operation of a network of high-level control areas that were preparing for an upcoming decision long before it entered into conscious awareness. Basically, the brain starts to unconsciously churn in preparation of a decision, and once a set of conditions are met, awareness kicks in, and the movement is made.
Regarding Sam Harris and his book, "Free Will"
'Indeed, Sam Harris
has made a compelling case that we don't have it, but that it's not a problem. Moreover, he argues that the ongoing belief in free will needs to come to an end:
Sam Harris States, "A person's conscious thoughts, intentions, and efforts at every moment are preceded by causes of which he is unaware. What is more, they are preceded by deep causes — genes, childhood experience, etc. — for which no one, however evil, can be held responsible. Our ignorance of both sets of facts gives rise to moral illusions. And yet many people worry that it is necessary to believe in free will, especially in the process of raising children."

Others prominent academics (philosophers primarily, such as Daniel Dennett) argue against the views of Sam Harris, however, those who's arguments are based largely on brain studies and neuroscience tend to lean toward the idea that free will is illusory.
