We read with great interest the recent article by Teichmann et al. [1], who presented results of the Free and Cued Selective Reminding Test (FCSRT) accuracy to differentiate typical (amnestic) Alzheimer’s disease (AD) from other neurodegenerative diseases. The authors assessed FCSRT in a group of 992 individuals, most of them with the diagnosis of AD, and stated that FCSRT would have a sensitiv...

Before Alan Turing made his crucial contributions to the theory of computation, he studied the question of whether quantum mechanics could throw light on the nature of free will. This paper investigates the roles of quantum mechanics and computation in free will. Although quantum mechanics implies that events are intrinsically unpredictable, the 'pure stochasticity' of quantum mechanics adds ra...
