Contact: [email protected] Using technology to improve the work of our brain is not science fiction, but something that actually happens. history. For example, cochlear implants are quite commonly used in deaf people: an electrode implanted in our body transmits an external stimulus (vibrations) directly to the brain, which interprets it as sound. So-called deep brain stimulation works well in blocking the symptoms of Parkinson's disease: stimulating a specific part of the brain using electrical impulses from an implanted electrode. Of course, questions arise as to how far this can go and whether humanity will be able to technologically improve subsequent brain functions. - There are no biological contraindications - answers my guest today, Dr. Paweł Boguszewski from the Marceli Nencki Institute of Experimental Biology of the Polish Academy of Sciences. We are talking about connecting the brain with technology. Of course: it is not easy. The basic problem is that the human brain is an extremely complex structure, the mechanisms of which we do not know very precisely. In fact, a major breakthrough in neuroscience has taken place before our eyes: scientists from the FlyWire Consortium have precisely counted and mapped all the neurons and neuronal connections in the brain of a fruit fly. The resulting brain map has about 150 thousand neurons and as many as 8 thousand different types of nerve cells. This is the first such precise description of the brain of a creature that can see and move, react by quickly escaping, a great thing. Meanwhile, the human brain has about 86 billion neurons! In addition, the connections between them are very complex and change. These are networks connected in networks interwoven with other networks. In the past, the brain was seen as a kind of reactive device: it receives a stimulus, reacts. Today, we know a little more. Neuronal connections in the brain work quite slowly, we collect small amounts of data from the environment. The main task of the brain is to check whether this data is consistent with what it expects based on the knowledge it has. A quick reaction occurs when the information collected is inconsistent with what we expect. "The brain is supposed to be a machine for prediction," describes my guest. Despite the difficulties in precisely understanding the functioning of the brain, intensive work is being done on connecting it with machines. Controlling devices, computers using brain-computer interfaces is already a fact. There are also chips implanted directly into the brain that read the patient's intentions and, for example, move the mouse cursor (the famous Neuralink). But is it possible to separate the mind from the body, which is not immortal after all? Can the brain function in a proverbial jar? The brain cut off from external stimuli still functions, although being cut off for too long is suffering for it. - You could say that a small brain is in a jar when we sleep - notes the neurobiologist. We do not have real external stimuli then, and yet the brain works intensively, memory processes work. The question is whether such a vision would be interesting. But what if we were simultaneously connected to the entire world in this jar via the network...? Be sure to listen, because the episode is dense with information and considerations!
