It serves to save our free will or power of origination. The following paper from The Journal of Theoretical Biology, first published undered the title 'The Time of a Conscious Sensory Experience and Mind-Brain Theories', looks into the the question.It was attended to confidently by Professor Libet -- Subjective Antedating of a Sensory Experience and Mind-Brain Theories: Reply to Honderich.Finding 2.1, which is crucial, appears to conflict with this.That is, the ordering by subjects of their experiences (experience-owed-to-skin-stimulus before experience-owed-to-cortical-stimulation) suggests that the experience of the peripheral stimulus occurs considerably sooner than about 0.5 sec later.Very roughly, findings 1.1 to 1.3 are to the effect that there is a certain delay in sensory experience, but finding 2.1 apparently conflicts with this.
This would be expected on the basis of 1.1 and 1.3.
Karl Popper and John Eccles, in The Self and Its Brain, depended on the research to argue for a certain dualistic picture, in fact a "trialistic" picture, since it includes the brain, and mental or conscious events, and something certainly distinct from them, the Self-Conscious Mind.
The research, naturally enough, also helps out with determinism and freedom.
(1.1) Experiments on human subjects, with their agreement, and in conjunction with surgical treatment, are said to show that after trains of stimulation are applied directly by inserted electrodes to postcentral cortex there is a considerable delay, up to about 0.5 sec after the beginning of the train, before cortical activity reaches "neuronal adequacy" for eliciting a conscious sensory experience.
What is said to be delayed, to repeat, is precisely the physical condition of "neuronal adequacy", as distinct from the experience itself, whatever is to be said of its time.
(3) Peripheral stimuli and subcortical stimuli quickly elicit a relatively localized "primary" evoked potential in somatosensory cortex, owed importantly to the specific (lemniscal) projection system.
