In the applause, Jiang Wei walked from the right side of the stage with a smile on his face. When they arrived at the center, the applause stopped, and Jiang Wei waved his hand to everyone again.

"I would like to warmly thank you for coming to the product launch site of Changheng Technology, this time, after years of hard work, we have brought you an epoch-making product from theory to reality - brain-machine instrument, please look at the big screen."

Behind Jiang Wei, a hard hat similar to a motocross motorcycle appeared, in terms of shape, there is nothing special, but the texture of the workmanship is quite exquisite.

Jiang Wei said: "In addition, I would like to thank one person in particular. We're sorry, but we respect his personal request, so we can't tell you your name. He didn't want to be disturbed by a lot of media after being exposed, but he provided us with very valuable information with selfless dedication, so that we could fill the data hole and design concept to bring you a perfect product. ”

At this time, a younger reporter in the audience asked: "Mr. Jiang, I just learned from the video that this so-called 'brain-machine machine' can read people's memory, can you tell us about its principle?" ”

Jiang Wei said: "Of course, the press conference is to let everyone know our products clearly, accurately and quickly. In the past few decades, positional cells, grid cells, head-facing cells, and boundary cells related to the cognitive function of the brain's spatial orientation have been discovered, and they together form the navigation and positioning system within the brain. You can take a look at this picture first. ”

At this time, a map of the human brain appeared on the big screen.

"There is a class of neurons in the prefrontal and posterior parietal regions of the brain, and their activity is closely related to the decision-making process. The activity of a single neuron can reveal the brain's thinking process when making decisions, and these decision neurons will integrate information on feelings, values, memories and other aspects in the process of thinking, and finally produce a choice variable, and the choice variable is dynamically presented in the calculation process, which means that the information will change over time.

In other words, the choice variable reflects the brain's thinking process of decision-making, and we can digitize it, and the information such as feelings, values, and memories generated by these decision variables is calculated after digitization. Our brain-machine machine, that is, the hat you just saw, is covered with hundreds of millions of electrode matrices, which can accurately and quickly compile the data-based calculation results, and finally present them on the screen in the form of a picture. ”

Another young female reporter in the audience asked: "However, how to distinguish whether the picture we see is real or imagined, after all, some people's imagination and spatial combination ability are quite rich." Also, is the picture we see as a complete composition of the person experiencing the event or only a vague focus, and if the latter is the case, will the key information not be extracted because of the person's neglect? ”

Jiang Wei smiled and said, "This lady, you can be regarded as asking the point, which is also what we had a heated discussion when we were positioning our products." If you don't mind, I'd like to invite you to come up and experience it for yourself, and it will definitely blow you away.

"Let's start with composition and focus, it's very difficult to maintain absolute awareness of everything around you, because the mind can quickly become overloaded with filtered information. The mind works better when it filters out the vast amount of information provided by the environment, such as sounds and sights, which is called focus in the term.

Of course, its counterpart is called marginal attention, which refers to the mind's ability to process information outside of consciousness, and to be able to pay marginal attention to a lot of what is happening. This unconscious mind includes our deeply repressed memories, so the final picture is not only complete but richer, and as for how to distinguish between fantasy and memory, we can choose the firing frequency of neurons by observing it, and the operation is very simple, like drinking water. ”
