Did Libet show Precognition?

Curious if someone has more data on this offhand mention of Libet's precognition claim in a Hammeroff Orch-OR paper:

Quote:But if hundreds of milliseconds of brain activity are required for neuronal adequacy, how can conscious sensory experience occur at 30 ms? To address this issue, Libet also performed experiments in which stimulation of thalamus resulted in an EP at 30 ms, but only brief ongoing activity, i.e., without neuronal adequacy (Figure (Figure9A).9A). No conscious experience occurred. Libet concluded that for real-time conscious perception (e.g., at the 30 ms EP), two factors were necessary: an EP at 30 ms, and several 100 ms of ongoing cortical activity (neuronal adequacy) after the EP. Somehow, apparently, the brain seems to know what will happen after the EP. Libet concluded the hundreds of milliseconds of ongoing cortical activity (“neuronal adequacy”) is the sine qua non for conscious experience—the NCC, even if it occurs after the conscious experience. To account for his results, he further concluded that subjective information is referred backwards in time from the time of neuronal adequacy to the time of the EP (Figure (Figure9B).9B). Libet's backward time assertion was disbelieved and ridiculed (e.g., Churchland, 1981; Pockett, 2002), but never refuted (Libet, 2002, 2003).


I dug a bit into the references but it's still not clear me to what Libet's actual, original claim was.

Thanks for the papers!
