 That said, it is worth noting that these features, while present in standard conscious experience, are arguably absent or diminished in unusual clinical cases, and in particular in “split-brain” patients. (See Bayne 2008 and Schechter 2018 for philosophical exploration of clinical accounts regarding the reports of split-brain patients.) This suggests a physicalist strategy of using these unusual phenomena as a tool for chipping away at the ostensible phenomenological basis for rejecting the possibility of an eventual physicalist account of consciousness. (See  entry on the unity of consciousness,  Sect. 4 for a survey of such disorders of unified consciousness and discussions of their possible implications.) An alternative, perhaps complementary physicalist strategy is to argue that certain seeming aspects of consciousness are simply illusions which can be explained in terms of inevitable organizational tradeoffs in the construction of finite minds (see Pereboom 2011 and Chalmers 2018).
