Well, I don't know about these two Australian neuroscientists. Here's what Cave is probably thinking about: Brasil-Neto, J.P., Pascual-Leone, A., Valls-Sole, J., Cohen L.G.. and Hallett, M. 1992. Focal transcranial magnetic stimulation and response bias in a forced-choice task. Journal of Neurology, Neurosurgery, and Psychiatry 55: 964-966.

Brasil-Neto and colleagues used TMS; subjects tended to use then hand contralateral to the stimulus, but experienced the choice as free. So what? Did anyone think that free will was incompatible with any causal powers influencing choices? Cave dismisses philosophy of free will in his review, but his article just illustrates the need for it. Brasil-Neto, by the way, is Brazilian.
