Breathing orchestrates synchronization of sleep oscillations in the human hippocampus

 

Go ask your competent? doctor which book is better for producing these oscillations. If your doctor doesn't know of both of these, your doctor is fucking incompetent! I take no prisoners in trying to get stroke solved, a lot of dead wood needs to be removed, probably your doctor!

Send me hate mail on this: oc1dean@gmail.com. I'll print your complete statement with your name and my response in my blog. Or are you afraid to engage with my stroke-addled mind? No excuses are allowed, leaders solve problems, you must not be a leader if you're preparing excuses for not getting patients 100% recovered! And what is your definition of competence in stroke? Swearing at me is allowed, I'll return the favor.

  • Significance

    Here, we suggest a hypothesis in which breathing underlies intrinsic coordination of sleep oscillations in humans. Brain rhythms during sleep coordinate activity across different neural systems, as part of memory consolidation processes. These coordinated sleep oscillations occur throughout non-REM sleep in bursts, and have widely been assumed to emerge intrinsically during sleep with no underlying rhythm or external impetus. Recently, however, sleep oscillations have been shown to coordinate on a slow timescale of about 3 to 6 s. Intriguingly, human breathing rates overlap with this range. Our findings show that human breathing drives a slow hippocampal rhythm during sleep, sleep oscillations in the hippocampus couple to breathing, and respiratory coupling promotes coordination of sleep oscillations, suggesting a role in memory consolidation.

    Abstract

    Nested sleep oscillations, emerging from asynchronous states in coordinated bursts, are critical for memory consolidation. Whether these bursts emerge intrinsically or from an underlying rhythm is unknown. Here, we show a previously undescribed respiratory-driven oscillation in the human hippocampus that couples with cardinal sleep oscillations. Further, breathing promotes nesting of ripples in slow oscillations, together suggesting that respiration acts as an intrinsic rhythm to coordinate synchronization of sleep oscillations, providing a unique framework to characterize sleep-related respiratory and memory processes.
