Researchers identify brain differences linked to insomnia
Salas and her team, reporting in the March issue of the journal Sleep, found that the motor cortex in those with chronic insomnia was more adaptable to change—more plastic—than in a group of good sleepers. They also found more "excitability" among neurons in the same region of the brain among those with chronic insomnia, adding evidence to the notion that insomniacs are in a constant state of heightened information processing that may interfere with sleep.Hmmmm, I wonder what it could be?
Why does the brain remember dreams?
High dream recallers, both while awake and while asleep, showed stronger spontaneous brain activity in the medial prefrontal cortex (mPFC) and in the temporo-parietal junction (TPJ), an area of the brain involved in attention orienting toward external stimuli.Guess what.
A little or a lot. Either you think in your sleep, or your brain is so active you can't sleep.
