GPS CELLS,AGAIN

WHAT IF ARTIFICIAL GPS CELLS, ARE INSERTED IN ROBOTIC BRAINS?

In 2014: John O'Keefe (British-American), Edvard Moser and May Britt-Moser (both Norwegian), shared the Nobel Prize in Medicine and Physiology, for the discovery of neurons constituents of a positioning system (GPS cells), located in the human cerebral hippocampus. For those who thought that this finding only served to guide us spatially externally and internally, the recent discovery of additional functions of these cells means that we are just at the beginning of a cognitive revolution of cyclopean proportions, of knowing the process of generating hypotheses  very close to  the same human thought. The study was conducted at the University of California, San Francisco by Loren Frank: 1-Frank and his team made  trained   rats run  by the central parts of W-shaped labyrinths, while other researchers monitored their positional neurons (mappers of the location of the rat). 2-When the rats were about to reach the other end of the central part, where they would decide which place to turn (right or left), the researchers noticed that the teta brain rhythm coincided with  the firing of  positional neurons, warning that as long as the rat did not decide which direction to turn, the position cells for both trajectories continued to fire  simultaneously in the central arm of the labyrinth. 3-As the rat approached the point where it should change direction, it was expected that position neurons would continue to be firing   simultaneously in events called theta cycles. 4-Instead and, until the rat turned, the position cells for each trajectory no longer fired   simultaneously, but in the form of alternate theta cycles. According to Frank and his team, the sequences of firing   of 125-milliseconds seemed to generate different brain hypotheses about the immediate future of the rats in a continuous, consistent and incredibly regular way, offering the animals, different future hypothetical scenarios, which allowed them  to weigh quickly and flexibly  the different scenarios, choosing the best option with opportunities to change options and even go back, useful  option to confront natural predators. For Frank, coding hypotheses is an explicit representation of the thinking and theta cycles: fundamental computational units, which the hippocampus uses to choose mostly abstract things, supported by previous experiences, adding that cyclical  firing   of  position cells imply, the development of cognitive faculties: imagination, planning and decision- making processes.

HIGH DENSITY EPIDEMIC OUTBREAK

TIME  TO  ACT, GLOBALLY

With 79930 infected people and about 2431 dead caused by the corona virus, in China alone, something fails to handle this partially contained epidemic outbreak. It is no longer an exclusive disease of China, it is global. It is time for the WHO to participate and issue a statement with the Chinese government, in this regard. We remain in our initial statement that we reproduce: “In megacities such as Wuhan, close human contact facilitates the easy installation and reproduction of the virus. The Chinese ruler Xin Pi has established a centralized quarantine (nobody leaves, nobody enters Wuhan). A mistake, because in that way Wuhan continues to retain its 11 000 000 inhabitants, in its many densified  apartment buildings, houses and overcrowded hospitals, when the right thing is for people to disperse and leave Wuhan going to the fields, forests, living outdoor tents or in  cities of lower density population. By increasing the person-person distances, the virus remains in the environment where it quickly dies or becomes inactive”. Watch CNN  today's video:Chinese authorities putting healthy people  in fields hospitals. 3,31 minutes, 

NOBODY LEAVES, NOBODY ENTERS WUHAN

CENTRALIZED  QUARANTINE

Until 03.02.2020, Chinese medical reports accounted for more than 20,000 infected and 426 dead due to the epidemic outbreak caused by the 2019 coronavirus in Wuhan, China. In our previous blog we stated : 1) that this outbreak was a challenge for the Chinese health system, not prepared for this peculiar outbreak and 2) That this outbreak corresponded to the disease model: high population density-easy spread of the virus. The dead and infected on the rise in Wuhan are due to the fact that in Wuhan, incorrect measures are being applied (centralized quarantine), successful in populations of 50,000 inhabitants or less.

In megacities such as Wuhan, close human contact facilitates the easy installation and reproduction of the virus. The Chinese ruler Xin Pi has established a centralized quarantine (nobody leaves, nobody enters Wuhan). A mistake, because in that way Wuhan continues to retain its 11 000 000 inhabitants, in its many densified  apartment buildings, houses and overcrowded hospitals, when the right thing is for people to disperse and leave Wuhan going to the fields, forests, living outdoor tents or in  cities of lower density population. By increasing the person-person distances, the virus remains in the environment where it quickly dies or becomes inactive.
