Article: When is Physical Pain Emotional Pain? [NoiJam]

“When treating an individual with CRPS [Chronic Regional Pain Syndrome] it may be useful for the PT [physical therapist] to be aware that sometimes it occurs with PTSD [Post Traumatic Stress Disorder].  In both instances the autonomic nervous system (ANS) is over-stimulated.  Our ANS connects our central nervous system, (CNS), to our organ, respiratory, and cardiac systems.  It is not under conscious control; however activities like meditation can have an effect on it.  Its two components, the sympathetic nervous system (SNS), and the parasympathetic nervous system (PNS) keep our life-sustaining body systems in balance (homeostasis).

“When we experience danger the SNS triggers increased heart and respiratory rates, raises blood pressure, and prepares us for fight or flight.  The PNS responds when we have no hope for escape and we freeze.  When we feel that the danger has passed, it returns to its usual function of reducing heart and respiratory rates and restoring balance to our systems.  The ANS is designed to be resilient in response to external stimuli.  But danger that continues over time can cause the SNS to remain in hyper-arousal which can cause CRPS, PTSD, and many other serious health problems.

“Emotional pain and physical pain are processed similarly.[i]  CRPS and PTSD manifest on a continuum similar to blood pressure which can go up with stress, but can also go down with meditation, or when the stress is relieved.  The nature of life is change, so the more appropriately the ANS ebbs and flows in relation to the environment, the more coincident body systems are with real-world reality.  A defining factor of CRPS is pain greater than would be expected.   PTSD is a complex state that includes fear and the experience of danger greater than the present reality.  For both, the exaggerated experience of danger may be triggered by a precipitating event.”

Article: Experiments Suggest Humans Can Directly Observe the Quantum [Psychology Today]

“It is important to note that this new understanding of the unexpected scale, accuracy, and precision of human vision, its capacity to directly access light at the level of single photons, and quite possibly also to determine the very quantum nature of light, has been developing within a larger context in the fields of biophysics and psychophysics, as well as in physics itself. This context, which also has not moved much into the realm of popular culture, nor even much into the overall scientific community itself, includes radical and revolutionary findings on not only vision, but on the other senses as well.

“Describing the recent research in his lab and others into human hearing, biophysicist A.J. Hudspeth of Rockefeller University reports (cited in Bushell 2018, link forthcoming), “Statistics concerning the human ear are astounding. The healthy human cochlea is so sensitive that it can detect vibration with amplitude less than the diameter of an atom, and it can resolve time intervals down to 10µs [i.e., microseconds, or millionths of a second]. It has been calculated that the human ear detects energy levels 10- fold lower than the energy of a single photon in the green wavelength…” Regarding human tactile and related senses (haptic, proprioceptive), it has recently been determined that “human tactile discrimination extends to the nanoscale [ie, within billionths of a meter],” this research having been published in the journal, Scientific Reports (Skedung et al 2013).

“Research into the human olfactory system has also recently been undergoing revolutionary progress, as it now appears to be part of a larger, organism-wide chemo-receptor system containing cells distributed throughout the body. The system appears likely to function via the mechanism of quantum tunneling of electrons within these olfactory/chemo-receptors (among other related mechanisms), and it has recently also been shown that the human olfactory sense is capable of discriminating over one trillion olfactory stimuli, as reported in the journal Science in 2014; the previous estimate was that the human olfactory sense could discriminate up to 10,000 different stimuli. (We will bring you more on this in much greater detail in a future post.)

“All of this evidence on the previously unsuspected precision, range, scale, and magnitude of the human sensorium is now converging from a broad range of scientific fields and researchers into a unified body of evidence, and a new and radical emerging picture, of the potential of human sensory-perceptual functioning potential. And, moreover, simultaneously in the very present, the discoveries – especially concerning the human vision of light – are being deliberately directed by a number of the world’s leading scientists and scientific institutions, to research into the very foundations of the universe.”

Article: Watch Nerve Cells Being Born in Living Mice [Science News]

“The scientists marked 63 cells called radial stem cells, which can divide to create new nerve cells. Researchers then watched these stem cells for up to two months, taking pictures every 12 or 24 hours.

“During that time, 42 of these stem cells underwent a spurt of division, churning out two kinds of cells: intermediate cells that would go on to produce nerve cells as well as mature nerve cells themselves. Once this burst of activity ended, the radial stem cells disappeared by dividing themselves into mature nerve cells that could no longer split.

“Many of these newly formed nerve cells had brief lives, dying either within the first four days, or 13 to 18 days after birth. It’s not clear what kills these newborn cells. Interspersed among the dying cells, survivors go on to knit themselves into the brain.”

Article: In the Deepest Ocean Trenches, Animals Eat Plastic

“For the past decade, Jamieson, a marine biologist at Newcastle University, has been sending vehicles to the bottom of marine trenches, which can be as deep as the Himalayas are tall. Once there, these landers have collected amphipods—scavenger relatives of crabs and shrimp that thrive in the abyss. Jamieson originally wanted to know how these animals differ from one distant trench to another. But a few years ago, almost on a whim, he decided to analyze their body for toxic, human-made pollutants such as polychlorinated biphenyls, or PCBs, which have been banned for decades but which persist in nature for much longer.

“The team found PCBs galore. Some amphipods were carrying levels 50 times higher than those seen in crabs from one of China’s most polluted rivers. When the news broke, Jamieson was inundated with calls from journalists and concerned citizens. And in every discussion, one question kept coming up: What about plastics?”
