This is very old pseudoscience with a recycled thin veneer of freshness. The idea that "quantum vibrations" in neuronal "microtubules" lead to decidedly macroscopic effects like detectable EEG signals is absurd on many levels, including spatial and temporal scope. There's also the small problem of neuron behavior modeling. Our existing biochemical and information-theoretical models are a very good match for the behavior of neurons.

The urge of tacking on some unneeded extra mystery baggage to distort a set of models that were already both well rooted in empirical data and accessible to rational analysis is an act of religiosity. It comes from, and speaks to people who share, a deep instinctive bias towards a metaphysical theory of consciousness - presumably because a purely physical model would be considered too mundane. The mere wish for a literal metaphysical transcendence does not make it true though, and in my opinion it also trivializes the amazing hardware that allows us to experience life.
