Cartesian dualism is long dead. In fact, dualism never lived. That, however, did not and does not stop imaginative people from oversimplifying from intuitive experience. Magic-thinkers insinuate dualism into explanatory gaps of highly complex, physical phenomena. Being many levels removed from their material substrates, complex phenomena are difficult to fully explain, particularly when their area of operation results in their being technically removed from easy experimentation.
Examples of erroneous dualistic thinking include "soul", "mind", and all deities. Goddidit is a non-explanation.
In this clip, Marcus Du Sautoy (Professor of Mathematics at the University of Oxford and the Simonyi Professorship for the Public Understanding of Science) participates in an experiment conducted by John-Dylan Haynes (Professor at the Bernstein Center for Computational Neuroscience Berlin) that attempts to find the neurological basis for decision making.
"Functional neuroimaging studies have started unravelling unexpected functional attributes for the posteromedial portion of the parietal lobe, the precuneus. This cortical area has traditionally received little attention, mainly because of its hidden location and the virtual absence of focal lesion studies. However, recent functional imaging findings in healthy subjects suggest a central role for the precuneus in a wide spectrum of highly integrated tasks, including visuo-spatial imagery, episodic memory retrieval and self-processing operations, namely first-person perspective taking and an experience of agency. Furthermore, precuneus and surrounding posteromedial areas are amongst the brain structures displaying the highest resting metabolic rates (hot spots) and are characterized by transient decreases in the tonic activity during engagement in non-self-referential goal-directed actions (default mode of brain function). Therefore, it has recently been proposed that precuneus is involved in the interwoven network of the neural correlates of self-consciousness, engaged in self-related mental representations during rest. This hypothesis is consistent with the selective hypometabolism in the posteromedial cortex reported in a wide range of altered conscious states, such as sleep, drug-induced anaesthesia and vegetative states."
