The brain could help fight epileptic seizures

Published

Today, many diseases remain incurable despite advances in technology. However, research is being conducted to find alternative solutions for some ailments. Recently, scientists made a startling discovery about the brain and its ability to terminate epileptic seizures. Tests continue to be conducted to have reliable results in the near future.

Indeed, it would be a excitation of the area responsible for epileptic seizures in affected patients. Experiments have shown that the brain has a certain elasticity which gives it a strong ability toadaptation. Ultimately, this discovery could be an alternative solution against epileptic seizures.

A small team of seasoned researchers is behind this interesting discovery. This group is headed by Professor Ko Matsui of the Super-network Brain Physiology Lab at Tohoku University.

The brain, a surprising organ

Since epileptic seizures are caused by a brain dysfunction, it would be entirely possible to reverse the process. It is for this reason that Matsui declares: “If an epileptic state can be created, we have to ask ourselves whether it is also conceivable to reverse the transition or to replace the existing hyperexcitable circuit with an additional suppressive system. »

In addition, other experiments carried out have been able to demonstrate that repetitive excitation of the area responsible for epileptic seizures leads to a epileptogenesis. However, to the surprise of the researchers, the more these stimulation are repeated, the fewer the responses to the stimuluss. Matsui (professor at the Super-network Brain Physiology Lab) declares to this effect: “Our brain has an infinite capacity for plasticity. »

In parallel, experiments were carried out on animals. Indeed, it was discovered that a paradigm of stimulation caused the release of adenosine, an endogenous inhibitory transmitter of glial cells. As a result of this study, the brain of a rat became strongly resistant to crises.

A very possible future use

Although the results experiences are far from disappointing, the scientists have some reservations. However, Matsui said: “Although epileptogenesis unfortunately cannot be reversed, we have shown that we can invoke the homeostatic nature of the brain circuitry to contain hyperarousal. »

He added : “Although the clinical use is still distant, it is possible to imagine a future where a therapeutic strategy can directly target glial cells and allow the creation of a resistant epileptic state. »

Samsung cheated: the unique S95B QD-OLED TV turned out to be better than the company describes it

Samsung cheated the unique S95B QD OLED TV turned out to

Earlier this year, Samsung introduced the S95B QD-OLED TV, which stands out with its new panel and 144Hz support. And with the last point there is a nuance.

Samsung cheated: the unique S95B QD-OLED TV turned out to be better than the company describes it

The fact is that the frequency of 120 Hz is indicated on the Samsung website, and the company spoke about it during the announcement. However, the TV was found to be capable of running at 144Hz while maintaining 4K UHD resolution.

The author of the HDTVTest channel conducted a series of tests and determined that the TV can indeed operate at a higher frequency than stated. At the same time, it works in full 4K UHD without various tricks like reduced vertical resolution and does not miss a single frame. Is that in this mode the color depth is limited to 8 bits.

In order to get the TV to work in this mode, you will need a PC, since modern consoles only support 120 Hz. You also need a video card with HDMI 2.1 and an appropriate cable. The author tested the novelty with the GeForce RTX 3090. Everything worked fine, including G-Sync.

The Samsung S95B QD-OLED is therefore a unique TV not only because of its new panel, but also because of its support for 144Hz at 4K UHD resolution.

Xiaomi 12 Ultra camera options have appeared They are fully

It seems that, at least in terms of basic characteristics, the Xiaomi 12 Ultra camera will be completely identical to the Xiaomi 11 Ultra camera.

Xiaomi 12 Ultra camera options have appeared.  They are fully consistent with the characteristics of the camera Xiaomi 11 Ultra

prototype Xiaomi 12 Ultra

The source published a list of parameters, indicating a 120x zoom, a focal length range of 12-120 mm (equivalent) and an aperture range of F / 1.95-4.1. All this exactly matches the camera specifications of the current Xiaomi flagship.

That is, the periscope telephoto camera will still be able to provide 10x optical and 120x digital zoom and will be characterized by an aperture of F / 4.1, the main camera will have an aperture of F / 1.95, and the ultra wide-angle camera will offer a focal length of 12 mm equivalent.

But this does not mean at all that the Xiaomi 12 Ultra camera will not change. The company can change all three sensors while maintaining the above parameters. At a minimum, the device is credited with a new Sony IMX 989 main optical sensor with an optical format of about 1 inch.

It remains to be added that the source of information is the Digital Chat Station insider, who was the first or one of the first to correctly list the characteristics of many Xiaomi smartphones and not only.

AMOLED screen and no 5G Motorola Moto G42 is getting

Motorola seems to have decided to take the bull by the horns and actively expand its smartphone lineup amid impressive sales growth in the US.

AMOLED screen and no 5G.  Motorola Moto G42 is getting ready for release

Motorola has already launched many new Moto G lineups, and the G42 is on the way. We have renders of the novelty and some characteristics. For example, it is known that the smartphone will receive an AMOLED screen, like the G41 and G52. For Motorola smartphones, this is a good option, as they have an unusually implemented Always On Display feature.

According to the FCC, the novelty will not have 5G support, so the smartphone can receive, for example, SoC Snapdragon 680 or MediaTek Helio G88/G96.

As for the design, it is as typical as possible for the current generation of Motorola smartphones.
