Brain oscillations. Teleportation. Real. Imaginary. The Snake.

Arne Ekstrom, associate professor at the UC Davis Center for Neuroscience, wants to know how we memorize places and routes, and learn to find our way around. It’s long been known that as a rat navigates a maze, its brain gives off a rhythmic oscillation, Ekstrom said. Most models of brain function assume that the oscillations, emanating from the hippocampus deep inside the brain, are at least partly driven by external inputs.

“There is this rhythmic firing in the brain during navigation and while remembering things, but we don’t know if it is triggered by sensory input or by the learning process”, Ekstrom said.

Ekstrom, postdoc Lindsay Vass and graduate student Milagros Copara were able to solve this problem by working with a group of patients being treated at UC Davis’ Department of Neurological Surgery. These patients have a severe form of epilepsy, and surgeon and study coauthor Kia Shahlaie implanted electrodes on their brains, inside the skull, to find out where seizure activity begins and identify treatment options. In between seizures, the electrodes recorded normal brain activity, and three patients volunteered to take part in the experiment. They were asked to navigate through a streetscape on a computer screen. At some points, they entered a teleporter and jumped to a different, known location in the map. During teleportation, the screen went black for a random period of time.

Teleportation did not interrupt the oscillations at all, but the rhythm did change with the distance travelled during teleportation, Ekstrom said. The results show that these oscillations are driven entirely by memory and learning processes in the brain, and do not depend on external senses. They also show that the oscillation carries information about speed and distance travelled, even when that travel is virtual teleportation. (1) [Journal Neuron Feb. 25, 2016]

Virtual. Real.

Mind. Senses.

We can sense the virtual.

We can think about the non-existing.

What more proof do you need?

Look for the snake.

It is here. And there.

It is everywhere.

Think about it.

Sense it.

It can fly…

Spiros Kakos is a thinker located in Greece. He has been Chief Editor of Harmonia Philosophica since its inception. In the past he has worked as a senior technical advisor for many years. In his free time he develops software solutions and contributes to the open source community. He has also worked as a phD researcher in the Advanced Materials sector related to the PCB industry. He likes reading and writting, not only philosophy but also in general. He believes that science and religion are two sides of the same coin and is profoundly interested in Religion and Science philosophy. His philosophical work is mainly concentrated on an effort to free thinking of "logic" and reconcile all philosophical opinions under the umbrella of the "One" that Parmenides - one of the first thinkers - visualized. The "Harmonia Philosophica" articles program is the tool that will accomplish that. Life's purpose is to be defeated by greater things. And the most important things in life are illogical. We must fight the dogmatic belief in "logic" if we are to stay humans... Credo quia absurdum!
