"As most neuroscientists and philosophers assume that consciousness is connected with the brain, their research is mainly
involved around establishing how the brain functions. Crick and Koch (1990), for example, talk about oscillations in the cerebral cortex whereas Dennett (1991), a philosopher has
developed a theory involving how numerous brain processes combine to produce a coherent response to a perceived event.
Even scientists who have combined quantum mechanics and
neuroscience such as Hameroff and Penrose (2014) and Fisher (2015) center their theories on
the brain and how it functions. Hameroff and Penrose (2014) claim that that their theory,
known as the "orchestrated objective reduction" ('Orch OR') theory, accommodates the view
that consciousness has been ever present and is derived from quantum vibrations in
microtubules, protein polymers inside brain neurons. "
