Hoping this forum is troll-free and mature

    Education:
    - Associate of Science in Electronics Technology 1980
    - Bachelor of Technology in Business Administration w/Management option 1991
    - completed pre-Dentistry coursework (including the less-required Molecular Biology course) 2004
    - Associate of Science in Dental Hygiene 2006
    - Bachelor of General Studies in General Sciences 2010

    As the well- rounded individual one becomes by age 58, I embrace many identities and have a few years work experience in the construction field (installing communications infrastructure as a Low-Voltage so-called Technician thinking it would be real technician work) while not embracing that identity.

    Among my identities:
    - God fearing man - a "believer", if you will, and I emphasize "believer" as opposed to most Christians, believers in name only
    - highly skilled experienced Electronics Technician greatly enjoying circuitry and software design and development
    - software developer specializing in what I call "office automation programming" (MS Office, etc.)
    - computer network administrator
    - CDL class A with the 3 popular endorsements and 16 months OTR
    - RDH in Colorado, but soon retiring that license

    Why I joined this forum: I googled "troll free forum". This forum was named by some random person as being one. I wish to bring my discussions over here that I started on a couple other forums. The topic is what is popularly called "primary perception". One of Mythbusters's episodes, entitled "Deadly Straw", air date 9/6/06, mangled their chance to demonstrate objectivity examining this subject. This world will benefit from utilizing this phenomenon, and I want to contribute to that end.

    Welcome to the PF. :smile:

    If you see any issues with trolls or immature behavior, just click the "Report" link in the post and the Mentors will have a look.

    Be sure to read over the PF rules if you haven't already -- you can get to them via INFO at the top of the page.

    Enjoy! :smile:

    Thank you kindly! I also found the "ignore" option.

    Note that discussions here must be restricted to mainstream science (i.e. that found in textbooks), and not personal theories. That is one of the reasons these forums remain troll-free!

    Thank you GREATLY for the guidance. Let me ask this question: I will be observing measurements on plant tissues starting with leaves taken using a Galvanic Skin Response Grove Module. The measurements will be observed for correlation to external stimuli. The nature of the stimuli will gravitate to mental telepathy AFTER I am comfortable with my measurement techniques. Note that I only received the module today and have an unknown learning curve ahead of me. I will be confining the basis for my forum activity to the measurements and correlation to stimuli that I and others observe. If my electronic measuring device fails to evidence the specific correlation, I'll have no basis for further discussion beyond seeking help with my measurement technique. Anything wrong with that so far?

    Again, I appreciate your reply!!!!!!

    No can do here...

    The gold standard is can you find a mainstream paper published in a peer-reviewed journal to base the discussion on.

    You've told me that I won't be welcome to seek advice here for electronic measurement technique in vitro just because of the planned FUTURE in vivo aspect of it? If I don't break forum rules in doing so, I appeal to a decision on this from a preponderance of the mentors.

    Seriously, Thank you GREATLY!!!

    You are free to ask questions within the mainstream. Once you invoke a non mainstream concept you will be violating the guidelines. Riding that line will be your risk.

    Question that might save me some time, as long as you are being this responsive:

    My OP will be in the form of a question directed to anyone having some experience measuring the electrical resistance of plant tissue if they can advise me on any of my concerns of signal-to-noise ratios and plant leaf surface contact materials and technique as well as advice toward equipment selection. Where would that question be appropriate?

    Thank you!!!!!

    Probably the Medical forum, since it deals with tissue contact electrodes?

    Do you have links to previous work of this type? How did they make electrical contact with the plant leaves? Do you just use the same contact pads as for an EEG or EKG?

    Classical physics could also be interesting.

    You'll probably need some sort of 4-point measurement. Non-isotropic resistance can be important as well.

    I would expect that if there is any galvanic action potentials at the points of contact. If I have to, I'll be investigating that possibility by varying the materials.

    The module I just received is limited to single-polarity measuring current. If I have to, I'll also be cutting the ground trace (a substantial one - goes to ground plane) and supplying a reversible reference to the the probe set in order to alternate the measuring current. Whether I need to go that far depends on the strength of correlation I might find. If weak, I'll alternate it.

    4-point resistance measurements? You mean Wheatstone bridge? I happen to have gotten a module based on conductance rather than resistance, either of which will satisfy me. The principles of measuring conductance use a bridge in a slightly different configuration than a standard Wheatstone, but regardless, it is contained within the electronic module not needing my modification except to adjust the gain...and change the polarity as I've mentioned.

    I chose medical

    Since this is "Member Introductions ONLY - No questions", so no discussions, this thread is closed.

    As long as you stay within the guidelines, you will be ok, make sure you also read any additional rules that apply to sub-forums, these will be pinned at the top of those sub forums.
