The recordable cerebral activity (readiness-potential, RP) that precedes a freely voluntary, fully endogenous motor act was directly compared with the reportable time (W) for appearance of the subjective experience of 'wanting' or intending to act. The onset of cerebral activity clearly preceded by at least several hundred milliseconds the reported time of conscious intention to act. This relationship held even for those series (with 'type II' RPs) in which subjects reported that all of the 40…

It was found that the final decision to act could still be consciously controlled during the 150 ms or so remaining after the specific conscious intention appears, and it was concluded that cerebral initiation of a spontaneous voluntary act begins unconsciously.

A modified hypothesis is proposed that for a peripheral sensory input, the primary evoked response of sensory cortex to the specific projection (lemniscal) input is associated with a process that can serve as a 'time-marker'; and after delayed neuronal adequacy is achieved, there is a subjective referral of the sensory experience backwards in time so as to coincide with this initial ' time-marking'.
