ScienceDaily (July 27, 2012) — Studies of lucid dreamers show which centers of the brain become active when we become aware of ourselves in dreams.
Which areas of the brain help us to perceive our world in a self-reflective manner is difficult to measure. During wakefulness, we are always conscious of ourselves. In sleep, however, we are not. But there are people, known as lucid dreamers, who can become aware of dreaming during sleep. Studies employing magnetic resonance tomography (MRT) have now been able to demonstrate that a specific cortical network consisting of the right dorsolateral prefrontal cortex, the frontopolar regions and the precuneus is activated when this lucid consciousness is attained. All of these regions are associated with self-reflective functions. This research into lucid dreaming gives the authors of the latest study insight into the neural basis of human consciousness.
“The general basic activity of the brain is similar in a normal dream and in a lucid dream,” says Michael Czisch, head of a research group at the Max Planck Institute of Psychiatry. “In a lucid state, however, the activity in certain areas of the cerebral cortex increases markedly within seconds. The involved areas of the cerebral cortex are the right dorsolateral prefrontal cortex, to which commonly the function of self-assessment is attributed, and the frontopolar regions, which are responsible for evaluating our own thoughts and feelings. The precuneus is also especially active, a part of the brain that has long been linked with self-perception.” The findings confirm earlier studies and have made the neural networks of a conscious mental state visible for the first time.
Damage to the DL-PFC can result in the dysexecutive syndrome,[4] which leads to problems with affect, social judgement, executive memory, abstract thinking and intentionality.[5]
The DL-PFC may also be involved in the act of deception and lying, which is thought to inhibit normal propensity to truth telling. Research suggests that by using TMS on the DL-PFC can hamper a person's ability to lie, or indeed to tell the truth
Consciousness
It has been suggested that together with the posterior cingulate, that the precuneus is "pivotal for conscious information processing"
Visuospatial
The precuneus has been suggested to be involved in directing attention in space both when an individual makes movements and when imaging or preparing them.[1][13] It is involved in motor imagery and shifting attention between motor targets.[1] It is also involved in motor coordination that requires shifting attention to different spatial locations

I will care about science and the brain when science acknowledges psi and begins to disseminate parapsychological findings, instead of ignoring them. Til then, science is just a bastion of scientism to me.

I do this offen! When dreaming I realise where I am and my circumstances in the dream and act accordingly. Most of the time I know I can fly and either fly to tops of buildings or with the wind. There have been times when I have flown to great heights and seen landmasses in the ocean to the curbiture of the Earth itself!
There is more information involved!

indeed,
Scientists will NOT be able to Locate the Seat of Meta-Consciousness in the Brain
only those areas of the brain Meta-Consciousness interacts/interfaces, or connects with.
they will, of course, continue to point at shadows projected on their screens
proclaiming them the real thing.
