Brain oscillations reveal that our senses do not experience the world continuously
(Medical Xpress) -- It has long been suspected that humans do not experience the world continuously, but rather in rapid snapshots.
Now, researchers at the University of Glasgow have demonstrated this is indeed the case. Just as the body goes through a 24-hour sleep-wake cycle controlled by a circadian clock, brain function undergoes such cyclic activity – albeit at a much faster rate.
Professor Gregor Thut of the Institute of Neuroscience and Psychology, said: “Rhythms are intrinsic to biological systems. The circadian rhythm, with its very slow periodicity of sleep and wake cycles every 24 hours has an obvious, periodic effect on bodily functions.
“Brain oscillations – the recurrent neural activity that we see in the brain – also show periodicity but cycle at much faster speeds. What we wanted to know was whether brain function was affected in a cyclic manner by these rapid oscillations.”
The researchers studied a prominent brain rhythm associated with visual cortex functioning that cycles at a rate of 10 times per second (10Hz).
They used a ‘simple trick’ to affect the oscillations of this rhythm which involved presenting a brief sound to ‘reset’ the oscillation.
Testing subsequent visual perception, by using transcranial magnetic stimulation of the visual cortex, revealed a cyclic pattern at the very rapid rate of brain oscillations, in time with the underlying brainwaves.
Prof Thut said: “Rhythmicity therefore is indeed omnipresent not only in brain activity but also brain function. For perception, this means that despite experiencing the world as a continuum, we do not sample our world continuously but in discrete snapshots determined by the cycles of brain rhythms.”
The research, ‘Sounds reset rhythms of visual cortex and corresponding human visual perception’ is published in the journal Current Biology.

so you experience the world through " pulsed DC" ...... interesting perspective

In the man there is the cardiac Rhythm, the respiratory Rhythm, that digestive, etc. etc.
It can be said that the presence of the Rhythm not only characterizes the existence of the living beings, but also of all that appears in the created Universe.
If we want to give the more possible synthetic definition of the Rhythm, we should say that it consists in an external alternate motion, that can have the form of a cyclical motion, both parabolic and spiral shaped, that expresses an inside Pulsation that expands and contracts continuously.
Now if the Pulsation is the inside aspect and therefore the hidden part of the Rhythm,the rhythmical spatial exterior movement of varing aspect, that manifests itself in less or more rapid succession, is all that can be known in apparent way,from the senses of a human being.
It is amazing to think as the Lumiere brothers( Lumière in french lingage means Light), with the invention of the cinema, they have revealed the rhythmic base of the creation to the world, but practically nobody has understood the true meaning of this extraordinary realization, that if from a side,it teach to create so likely illusions, to be able of to excite, to move, to frighten who looks it, at the peer of the most common events of the life, from the other side it stimulates to seek beyond thesensorial appearances, the true nature of the reality.
The work of Lumière brothers, has been a strong recall, but entirely misunderstood, to the revision of the fundamental principles of the cognitive sensorial methodology, a recall completely ignored and misunderstood, but only considered in it superficial aspect of simple show.
From Ighina,I have learned the Law of the Rhythm, of which Light and Matter are the opposed polarity of manifestation and the causes of the Stroboscopic Effect, that is the "veil" that hides to the men, the true nature of the Reality.

Research opens doors to UV disinfection using LED technology
Research from North Carolina State University will allow the development of energy-efficient LED devices that use ultraviolet (UV) light to kill pathogens such as bacteria and viruses. The technology has a wide array of applications ranging from drinking-water treatment to sterilizing surgical tools.
