It is still widely dismissed. And while coherence seems to be relevant for a particular stage of energy conversion in photosynthesis and also in allowing sensitivity to magnetic fields, the mechanisms for leveraging these are incidental. They are used passively to achieve an effect and not actively to perform computations as would be required for Penrose's hypotheses. To claim the brain leverages quantum effects at biological scales is going far but still plausible. But to say that quantum computations are going on in the brain and are expressed at the level of thinking we acheive (evinced by claiming that we are not Turing machines), that is something that would require a lot of data to support (something that this theory sorely lacks). Much of what we know about quantum mechanics and neurobiology would have to be redressed. Indeed if such were true there would be indirect evidence - I expect we would find quantum mechanics, heck ordinary probability theory, more intuitive for example . Far more interesting are the epigenetic like effects that occur in memory formation.
