The functional activity of a brain area may vary with changes in its inputs as most
dramatically illustrated by the neural plasticity involving recruitment of dedicated
brain areas to subserve new modalities such as the visual cortex in Braille learning. |

Dream process is seen as having
no primary ideational,
volitional, or emotional
content.
Forebrain is
assigned an entirely passive role: it's external
input and output channels are blockaded by brainstem mechanisms, its perceptual and motor engrams are activated by brainstem mechanisms, and it's memory
systems merely generate the best possible fit of intrinsically inchoate data. [Gestalts]

Memory consolidation refers to neural processing that occurs
after information is initially registered,
which contributes to its permanent storage
in memory. |

Long-term potentiation (LTP) is optimally elicited in the hippocampus with stimulation at theta
frequencies (5-7 Hz or pulses
separated by 170-200 ms). |

We believe the case is strong
for the involvement of theta rhythm in mnemonic functions of waking but not of REM sleep. |

Our position is that the theta rhythm of REM sleep is a byproduct of the intense activation of the pontine region of the brain stem in REM sleep. |

During REM sleep, ponto-geniculo-occipital (PGO) waves originate in the pons and activate the forebrain. |

Forebrain
attempts to make sense of the random
activation by the PGO
waves,
and it synthesizes dream images to fit the patterns of internally
generated stimulation. [Gestalts]

as
a possible function of dreaming during REM sleep. |

Negative emotions such as anxiety,
fear, and panic, can be seen as adaptive
responses that
increase fitness in dangerous

of brain areas required to simulate emotionally charged, threatening events. |

Allan Hobson
suggests that the function
of dreaming is memory consolidation and the linking of memory representations
with motor programs. |

It is doubtful that dreams have any adaptive function. There are too many
people including children and brain lesioned patients, who sleep
adequately without them, and no evidence that
either recalled or remembered dreams have any functions. |

Dreaming is a cognitive achievement that develops
throughout childhood. There is the forebrain
network for dream
generation that is most often triggered
by brainstem activation. |

is the problem of explaining how subjectivity can arise from complexly

Chalmers
has pressed the line that even if we are provided with a complete
neurobiological theory of how the brain works, nothing will have been done to
erase the intuition
that there is an unbridgeable gap between the way the organized
objective brain works and the first-person grasp
I have of myself as a thinking-feeling creature. |

It is amazing that consciousness can emerge from brain processes. Explaining the mechanisms that give rise to the different types of waking consciousness, NREM, and REM mentation, is all there is to
solving the "hard
problem." |
