Neurosurgeans on science behind severance pay

SmarriageThe highly popular Apple TV+ series about office employees who have undergone brain surgery, the fact that hosts do not have knowledge or memory of their working selves and vice versa, usually defined like science fiction. This is a reasonable characterization, because the simple standing treatment that separates a person in the office between a “innate” and a “outrie” at home is not available for the rest of our brain surgery.

However, the science described by the show is still fans of many brain experts and neurosurgeons, as they move beyond everything that is currently possible. “I love Condemnation Because it creates an important function that the brain looks at it without even realizing it, J Kap Jordina Rincon-Torroella, Assistant of Neurosurgical University, builds our identity only by informing ourselves, our experiences and our own inner drama.

We asked Rincon-Torroella and other brains that followed or familiar. Condemnation Brain surgery and thoughts about how everything is depicted in the show.

The presence of a clean and very convincing brain surgery

The first step of the change of the brain is to physically enter the brain, where the sci-fi of the seniority is first poured into science. Although the term “neurosurgery vermek calls a cut skull releasing a pink, vibrating mass, the surgery experienced by the subjects includes a small hole in the back crown of the skull and a small chip in the bottom of the brain. The procedure is fast, simple and these things are increasingly bloodless.

Such minimal invasive surgery is not at all except the possible realm today. Dr. Hackesack University Medical Center Functional and Restorative Neurosurgy Director Dr. Hoomin Azmi says, iz We can treat tumors or regions of the brain that causes epilepsy by drilling a small hole in the skull and placing a laser probe under the visualization of MRI. “We can then watch the tumor burned in MRI.”

Surgeons Condemnation Do not use such sophisticated imaging, just look at the brain and place the chip manually and make it correct each time. “In terms of surgery [in the show]Clearly a little science fiction, “he says.

Some types of neurosurgery do not require the opening of the skull. Aneurysms – or bubbles in an artery wall – can be processed by passing a probe from an artery in the groin or an artery up to the brain and closing the affected area with a coil or stent.

“This has greatly changed the results and complications for patients, Az says Azmi. “I think the days of brain surgery in the office are still far from us. However, the orbit of less invasive and safer neurosurgery has been going on for several years.”

Some procedures are less invasive, which does not come into contact with the brain tissue. Transcranial Magnetic Stimulation (TMS) Applies magnetic impacts to the scalp to treat major depression symptoms. The focused ultrasound can be irradiated from the skull and can reduce tumors or surgically without any confidence in a drill or a scalpel. “At the same time, patients with basic shaking help us with the centers of the brain, or an uncontrollable tremor in patients with fundamental tremors,” Rincon-Torroella says.

A less realistic depiction of memory control

Condemnation The memory is more scientific freedom when it comes to the part of the manipulative chip. The region in the crown of the head is known as parietal lobe, and when parietal is doing a lot of work – it is not the place where the memory is experiencing sensory information such as touch, temperature, pain and spatial awareness.

The ability to create short -term memories is managed by hippocampi, two buildings in the depths of both brain hemispheres. But Server of other parts of the brain– including Fornix– BASAL GANGLIYES– thalamus– amygdala– Kaudat kernelAnd prefrontal cortex– Play the role in combining and storage longer -term memories. This is too much neural real estate for a chip placed in parietal.

At least he says that a chip that changes memory should target a hippocampi for the amygdala, which manages memory -creating functions and emotions. “Memory and emotions are very connected to each other, or he says. “These would be areas where I would try to approach if we think that we could divide an identity.”

However, it may not be recyclable to close the key brain areas. Prof. Dr. Nyu Langone Health Assoc. “For example, you can remove the short -term memory if you have closed or broken both hippocampi and Fornices, Dan said Daniel Orringer. “People couldn’t create these memories, but it’s a destructive thing.”

Azmi does not believe memory control Condemnation The supports are completely outside the possibility area – not only predictable future. “We will probably reach the day where we can choose memories and choose other memories, or he says. “I think these years are far away.”

Even if it was possible to switch back and forth between two or three brain regions, this would not be enough to create binary identities within the characters. Condemnation exhibit Nyu Langone Health Vice President of the Neurosurgery Department “The memory is very complex and contains many different parts of the brain, Howard Riina says. “At the same time hemispheric; there are memory components on the left side of the brain and on the right side of the brain. A chip must have some kind of global effect from an area where he is implanted.”

Potential of brain chips

This may not be possible with the existing technology, but Implante brain chips that work locally in a single -target region of the brain are already being developed. California -based Neurralink is trying to create computer chips that can be implanted in the brain and allows quartly to control computers and other devices with their thoughts. Braingate, which has a consortium of neurologists, engineers, computer scientists and more, implants electrodes in the brain, not chips, Similarly allowing Sometimes people with a stroke, ALS or brain stem hit by thinking to manipulate a paralyzed arms and hand to manipulate a computer cursor. Deep brain stimulation-Parkinson’s disease and epilepsy and epilepsy, tourette syndrome, dystonia, and more, are already used to control the tremors related to the targeted areas of the brain.

He says, “You have people with injuries, they have strokes, they have traumas, there are cerebral palsy,” Riina says. “You can increase these people, even use different parts of the brain to compensate for the damaged area.”

Increasing, inhibiting or manipulating consciousness and identity, including memory, there will be a heavier lifting in an isolated area of ​​the brain than to treat injury or disease, and Condemnation It makes good TV, does not call rational science – at least not in a remote predictable future.
