Wow...just wow. Why are you in a science forum? Doesn't the right believe in science? And hasn't science benefited from government support?

I couldn't agree more!

I've never been disappointed in America; it is one of the greatest countries in the world to live in particularly for the freedoms it allows and its previously stable governance, which is more in doubt around the world now than ever before (IMO). What I find disappointing are Americans with access to the truth who deliberately espouse uninformed and untruthful views such as those you seem to support. The truth about Obama is that he left office with this economy in a condition far superior than when he arrived--and did so without the support of a Republican majority.

It seems that our current administration is steering a course predicted 40 years ago by lines in a long-running British science fiction series, Doctor Who. According to the Huffington Post, the lines were "You know, the very powerful and the very stupid have one thing in common. They don’t alter their views to fit the facts. They alter the facts to fit the views." How remarkably apt.

Judging by debates I've engaged and observed here, I don't think Trump supporters particularly care about truth.
-
Much of his candidacy and subsequent election was based on "alternative facts". We shouldn't expect his administration to be any different.
-
Yet again, more evidence of Mr. Trump nominating wolves to guard the sheep and what happens when delusional sheep elect wolves to lead them.
-
Yes there is, as I'm discovering.

The host of this YouTube video on the language of the Aztec asks "have you ever wondered what Aztecan really sounded like?" I did and have so since I first became aware of this great civilization, its culture, and its artifacts. Unfortunately, much of what we commonly understand about their pronunciations are Spanish filtered but this video teases out the correct pronunciations for such things as flower (xochitl), chocolate (cacahuatl), and Montezuma (Moteuczomatzin). It's an interesting video on the unique quality of an ancient language.

Are you suggesting that he shouldn't trust the media at all or only when they report the stories that you agree with?

Synaptogenesis is not evidence of the quantum quality you've described, in my opinion and according to the link I've provided. The reference link you provided described a neurochemical process rather than a quantum exchange or conveyance of energetic particles between neurons, as we might observe in quantum physics. Although endocannabinoid receptors may be a factor in synaptogenesis, there are other factors of equal importance to our CNS. If this regards the quantum chemistry of neuronal exchanges, we should be probably be discussing those exchanges at their molecular level--which hasn't been the focus of this discussion and your links thus far.

I agree; unfortunately, extrapolation is a norm for most animal studies. As I understand the 2014 study, lower temperatures did produce "a less efficient antiviral defense response of infected cells". If this is true, then my next question would likely be how does cold weather lower our antiviral defenses rather than why would there be a mechanism for that lower response in cold weather? A down-regulation of our defenses in cold weather certainly seems a counterintuitive response unless the response mechanisms are specifically keyed to tropical or warm weather viruses, which might be more plentiful than cold weather types.

It's my understanding that software is available for high resolution photographs as long as they are digitized. For example, I found this facial software company after a cursory Google search. This company claims their software can track a multitude of physical features and is used by both "video and image archives". This is one of several different software companies I found, after a brief search, that could provide you with solution you seek.

According to this 2014 study, also reported in this New York Times article, "...cooler temperatures can enable replication of the common cold virus, at least in part, by diminishing antiviral immune responses." Replication occurred in the lungs and nasal cavities of test animals at lower body temperatures that could be caused by lower ambient temperatures, which seems to suggest a link between exposure to cold weather and certain viruses.

Primarily, your self-preservation and survival. As an essential survival tools, news is a means by which you are informed and prepared for possibilities and eventualities that may significantly impact your ability to protect and support yourself, your lifestyle, and your family.

I'm no expert, but have you considered adapting facial recognition software to your needs?

The idea is to get the parents to think about their beliefs by asking questions leading them to probe those beliefs. This isn't necessarily an imposition of external reasoning but an effort to get them to rely on their reasoning rather than their feelings or beliefs.
-
I agree; asking questions that appeal to reason is the first step to successful persuasion.

Three Networks of the Brain?
DrmDoc replied to dsmart's topic in Anatomy, Physiology and Neuroscience
I believe you are asking about executive functions, which are mediated by our central nervous system (CNS) primarily through our prefrontal cortex. Rather than a system of nerves, the prefrontal is a neural structure whose functional matrix adds a quality to our cognition and behaviors that enables focused activities and pursuits. Regardless of what behaviors we engage, those behaviors are governed by neural structures comprising our CNS whose commands are executed through its connections to the various subdivisions of our neural system. Other than our enteric nervous system, no other neurological system in our body exercises a similar degree of independent governance. The governance of our behaviors resides within the various structure of the brain. Our various nervous systems are merely the dedicated neural links through which our brain executes its governance. -
If it were me, as in any argument or attempt to persuade, I begin with an effort to genuinely understand the patient's parents fears from their perspective. I would try to get at the basis of their fears and use that information to help them make a decision that is ultimately in their child's best interests. The approach is not to convince them that their perceptions are wrong but that the correct perception or decision is their idea, although you may have led them to it. For example, if after asking, really listening, and not being arrogantly dismissive, I determined that their fears are based on something they've read, I'd ask "how well do they trust that publication?". The idea or objective here is to get them to think rather than feel. To do that, you have to ask questions that lead them to rational thought and to trusting you more than some disinformation. After all, their children wouldn't be in your office, if they weren't willing to trust you. Asking questions get them to think and use their own reasoning to arrive at your conclusions, which they will if your conclusions are sound.

Three Networks of the Brain?
DrmDoc replied to dsmart's topic in Anatomy, Physiology and Neuroscience
As I understand, the idea of three neural networks is merely a characterization of three brain states rather than active or actual neural networks within our nervous system, which consists primarily of two: The central and peripheral nervous system with the latter subdivided into several others. The video by Mr. Weber discusses a theoretical model of brain function proposed by Andrews-Hanna, et. al., in a 2014 paper. In that paper, the authors propose a distinction between their idea of a "Default Network" and a theorized "Default Mode" idea stating that "We use default network instead of default mode because the latter refers to passive states, which may obscure the adaptive functions of the network. The former is meant to emphasize its role as a large-scale brain system whose functions may extend beyond the resting state." The latter "default mode" was first described as a model of brain function in a 2001 paper (Raichle,M.E.etal.2001. A default mode of brain function. Proc. Natl. Acad. Sci. U.S.A. 98: 676–682). A further discussion of default network research can be found here. In my opinion, this idea of distinct neural networks is best described as brain states or modes of activation rather than dedicated networks with separate on/off switches. True networks are verified by real afferent/efferent neurophysiological links rather than concurrency in activations and deactivations through functional observations. Neural networks refer to real neural links that perform specific or dedicated tasks. Much of the tasks described under this default network model is ascribable to our parasympathetic nervous system, IMO, which is a subdivision of our peripheral nervous system. Although certain areas of the brain are observed as active during a particular brain state or mode, those areas may also be active during others unrelated states or modes. For example, our brain is just as active amid its dreaming state as it is while conscious, excluding prefrontal function depending on dream type. Those brain areas active while dreaming cannot be described as a dedicated "dreaming network" because those areas are also active when we are awake. Simply stated, there are no neural networks specifically dedicated to the three brain states in your references. Much of what our brain does and doesn't do is controlled by the thalamus--perhaps our most misunderstood brain structure, in my opinion. -
Three Networks of the Brain?
DrmDoc replied to dsmart's topic in Anatomy, Physiology and Neuroscience
To your initial question, the answer is no; therefore, your remaining questions are moot. What was or is your source for this three network idea? For a more accurate perspective, I suggest you begin here with Large Scale Brain Networks and Biological Neural Networks for more detail. You might also want to acquaint yourself with Neuropsychology and it functional approach to brain study. I hope this helps. -
I have a question about "higher" dimensions
DrmDoc replied to horrible_at_math's topic in Modern and Theoretical Physics
As a novice, I have very little to offer here other than this link to a prior discussion on higher dimensional spheres. This discussion includes a link to a PBS Infinite series video exploring the topic of higher dimensions. I though the video was very interesting and informative. Perhaps you will as well. -
If I may inquire, what are the practical applications of this quantum approach beyond those conventional neuroscience provides? How is this information uniquely useful or more useful than what we already know through traditional neurological research?
-
The distinction I've tried to convey is that you are attempting to supplant facts with theories. What need have we for theories when we have incontrovertible facts based on unassailable evidence obtained through empirical research in neuroscience?
