There are neurological and psychological components to understanding the nature of dreams, dream function, and the sleep process overall. Since you have posted to the Neuroscience Forum, I can tell you that research suggests that the sleep process overall, which includes dreaming, serves the metabolic needs of brain and body. In the brain specifically, the sleep process removes accumulated cell waste and toxins more efficiently (Glymphatic System) and restores the brain's glucose and oxygen reserves (glycogen). Even more specifically, dreaming elevates activity in the brain, which increases our respiration, heartrate, and delivers more glycogen restoring blood to the brain. Dreams, the imagery and experiences we recall upon arousal from sleep, are how our waking brain synthesizes the lingering neurological effects of the activity it engaged amid sleep. Our dream recall forms amid the incongruity we sense between the lingering mental effects of dreaming and the real physical perceptions we experience during arousal from sleep. Toilet and bathroom dreams are very common. One could suggests that such dreams reflect how our waking brain interprets the lingering neurological effects of the glymphatic process. However, your dream may have deeper, psychological implications not explained by this process. After years of study, it is my opinion that dreams and dreaming have material value beyond our neurological sphere of interest.

My optimism and faith in humanity is restored! Thank you!

I appreciate the info. What I find so interesting about all this it the term immortal ​and what that suggests relative to human cell study. Thanks again.

Ditto!

He the PT Barnum and Gorgeous George of the political circus and arena. He's an entertainer; although, I felt similarly about Arnold Shwarzenegger when he ran for Governor of California and Ronald Reagan for POTUS--Doh and Yikes!

Interesting; if I may inquire for further study, what are the other prominent immortal cell lines and do you have a link to your source? Their history and likely contributions are intriguing given their purported unique qualities.

Here is a link to the article announcing this expected discovery confirming Einstein's prediction. The article provides several informative links on subject and it's current research. Data results from the LIGO (Advance Laser Interferometer Gravitational-Wave Observatory) experiment will be released Thursday. Ripples in space-time detected, wow!

Perhaps you misinterpreted the tone of my inquiry as I did your intial reply. Being unfamiliar as I am with Mrs. Lacks contribution, your initial reply suggested to me that Hela was overstated by my source. You wrote that Hela "may not even be the first [immortalized] line" and then, directly after wrote "I am pretty sure it was the first successfully immortalized cell line." ​In subsequent comments you wrote how the robust nature of Hela led to "faulty" research results. Further still, your comments seemed to lessen Hela's significance as merely a "workhorse" and "not as important as they once were" rather than the continuous source of medical breakthroughs and discoveries as my source suggests. I was merely asking for clarification as you seemed to be more knowledgeable than I on this subject. As the negative ratings and your subsequent reply suggests, the written word isn't always received the way it is intended. Nevertheless, thank you for sharing your thoughts.

Perhaps I misunderstood the tone of your comments but are your saying that the value of this African American's illicitly obtained immortal cell line was overstated because of pre-existing cell lines and that the measure of her line's importance to medical research was or is inconsequential?

Is anyone here familiar with the contribution of Henrietta Lacks to immunology, microbiology, chromosome study, and an endless array of other scientific endeavors? Well, it seems that she has provided medical science with the first and only source of immortal, lab grown human cells. Mrs. Lacks tumor cells, extracted during her cervical cancer surgery, have been replicated and continually used in medical research around the world since 1951. This Ted-Ed video link discusses Mrs. Lacks contribution and an array of medical discoveries that would not have been possible without her extraordinary cells. Mrs. Lacks, who was African American, died of cervical cancer in 1951. She was not aware that her tumor cells would be used for research and her family was not informed until the late 1970s. I find myself wanting to know more about Mrs. Lacks and the medical breakthroughs her contribution continually provides.

I agree; procrastination is either about pure laziness or about avoiding some unpleasant experience. Either way, procrastination is likely the healthier alternative given the negative effects of continuous stressful experiences .

Unfortunately, pure science and history programming doesn't attract the viewer demographics these channels require to acquire and maintain sponsors. The reality is that these are businesses that require steady streams of commercial support to provide the programming we enjoy. To do that, they have to compete with the intellectually disinclined programs of more commercial channels by producing pseudoscientific shows with content of mostly fringe interest or appeal. Gone are the days of Science and History Channel programs produced solely for some intellectually edifying content. Loyal viewers will have to content themselves with occasional flashes of truly insightful science and history between visages of aliens and hauntings.

I'm reposting this Men's Health video link because I believe it provides invaluable insight as to why procrastination could be detrimental to our health. Procrastination, which is likely something we do or have done, results in the release of stress hormones which triggers the production of white blood cells that could become resistant to the cortisone keeping those cells in check, according to the video. It goes on to describe how unchecked white blood cells could damage otherwise healthy organs. In retrospect, I think this video is more about the effects of stress rather than procrastination because I do not believe procrastinators experience the associated level of fear that produces stress behavior. PN: ​Forgive my earlier faux pas regarding the video rules, sincerely. I will review them immediately after a short nap, a hot meal, afternoon tea--this is so stressful--maybe tomorrow.

I agree; as you've observed, there are several plausible explanations that we cannot confirmed without more complete samplings or data. Although, like you, I do favor some "isotopic re-equilibration" as most likely. So, perhaps, it's indeed a bit too early to make certain definitive declarations regarding Earth-Theia impact.

I agree, but there's still the question of those "indistinguishable" isotopic results. Could it be that their study results are based on Moon rocks not obtained through core sampling? Isn't it likely that samples closer to the Moon's core would yield rocks more reflective of Theia's distinctive profile thus validating the prevailing theory?

This Men's Health video provides very convincing physiological evidence as to why we should be more responsive to the immediacy of responsibilities. Enjoy!

Well, here is a link to the January 28th press announcement from the UCLA team behind this latest version of Earth/Theia impact. The article is titled "Moon was produced by a head-on collision between Earth and a forming planet". Enjoy!

Indeed; however, from my reading of the article, the prevailing hypothesis has been an indirect, less energetic "glancing" collision rather than what is now indicated by current research, which suggests a direct, more highly energetic impact. The glancing theory infers our Moon as predominately comprising the remnants of Theia rather than a homogenized version of both Earth and Theia as the article purports based isotopic research.

I agree; why is there this seeming presumption that Earth and Theia would not have the same oxygen isotopic profile? What is the argument or evidence supporting an initial distinction between the two planets? If the original isotopic distinctions between the planets remain undetermined, shouldn't the "glancing" impact theory remain equally as likely as the newly theorized direct impact? Regarding the idea of an Earth captured Moon, how does that align with the Moon's widening orbit from its inception?

The amygdala, which is one of several structures comprising the limbic system as iNow informed, is key to emotional expressions including aggression. Although amygdala function is central to aggressive expression, mediation of that expression involves a concert of brain activity primarily governed by prefrontal brain function. If the amygdala was a child, then the prefrontal would be considered its parent. Prefrontal function informs us that our actions have consequences, which is something a child is capable of learning with normal prefrontal development. Additionally, decerebrate cat studies have associated certain aggressive postures with hypothalamic function. Cats with brain structures surgically removed to the hypothalamus level engaged this rigid behavior whenever aroused. Regarding the amygdala, it isn't so much that its function causes aggression than its malformation disinhibits certain aberrant behaviors.

News of the day, Earth comprises the merged remains of Theia. According to a recently published article in Science, Theia--the Mars sized planet at first believed to have caused our Moon's creation through a "glancing" impact with Earth about 4.6 billion years ago--is now believed to have directly impacted and completely merged with Earth, which "indistinguishable" oxygen isotopic studies appear to suggest. Could there be another explanation for Earth/Moon shared isotopic profile? I welcome your thoughts.

Well, Duh! Actually, I ate quite a bit when I was a child back when it was packed with greater levels of lead emissions before emission standards changed. Here's an interesting DNews video on why you shouldn't let your child eat snow. Enjoy!

From another post: Here an interesting , which attempts to explain the idea of “’thinks’ in the absence of language”. This link will take you to a YouTube video providing an introduction to the Corollary Discharge Theorem, which provide one explanation in neuroscience for our inner voice.

I think, based on the only testable examples, that mind is a product of a dynamic cognitive process involving the integration of sensory perceptions and stored memories to produce the behavioral responses we recognize as evidence of a mind. Essentially, mind is a product of some source process. If mind is a projection that exist outside brain function, what is the source of that projection and how can we prove that assertion? I think some of us construe our environmental or social influences as projections of mind from some omnipresent or omnipotent source beyond ourselves. In reality, those supposed projections are merely the terrestrial perceptions that feed the dynamic functional brain processes that produce those behavioral responses confirming the presence of mind. Again, in my opinion, mind is the product of a functional process quantifiable by what we can prove through the only testable example, which is brain function.

No, can you? You are missing the point, the mind is not part of the body, the body is a hologram created by the mind! "it is your mind that creates this world" No, I can't prove that the mind is a product of something other than brain function. However, I can prove--through an abundance of brain trauma studies--that a mind is not evident amid brain death, which is very convincing evidences of what produces the mind, in my opinion.
