Difference Between Invasive and Non Invasive Procedure


The human brain is an amazing thing. It controls our every thought, movement, and emotion. And researchers are now finding ways to tap into its power using a technology called a brain-computer interface (BCI). BCIs allow people to communicate with computers and other devices using their thoughts alone.

How Brain-Computer Interface Works

A BCI works by collecting brain signals, analyzing them, and converting them into readable commands that are then relayed to an output system to perform the desired action.

Invasive Brain-Computer Interface

Invasive vs Noninvasive Brain-Computer Interface (BCI)

There are two main types of BCIs: invasive and noninvasive. Invasive BCIs require surgery to implant electrodes directly into the brain. Noninvasive BCIs use sensors that sit on the surface of the skull and don’t require any surgery.

Invasive BCIs are injected directly into the brain during neurosurgery. There are single unit BCIs, which detect signals from a single region of brain cells, and multiunit BCIs, which detect signals from different regions.

Both types of BCIs have their pros and cons. Invasive BCIs can provide a more direct connection to the brain, which can make them more accurate and reliable. But they also carry risks such as infection and bleeding. Noninvasive BCIs are less risky but may not be as effective as invasive ones.

The majority of non-invasive BCI systems rely on electroencephalogram (EEG) signals. electrical brain activity measured using electrodes mounted on the scalp.

The choice of whether to use an invasive or noninvasive BCI depends on many factors, including the person’s medical condition, preferences, and goals for using the device. Ultimately, it’s up to the individual and their doctor to decide which type of BCI is right for them.

Why Brain-Computer Interface is Important

BCI can be a game-changer for humanity because BCI has so much potential. A person with a disability can use technology with little to no effort and learning can very easy. People who don’t have limbs can use prosthetic limbs with the brain like we usually do with our natural limbs.

And BCI can allow us to become digitally immortal by uploading our consciousness to a computer or a robot.

O’neill cylinder vs Stanford torus


 As you all know, Elon musk’s SpaceX is trying is colonize mars, and it’s a traditional method of colonizing any species on any planet, but there are a few methods for colonizing species on another planet.

And this what a Space colony is about, In theory, a Space colony is something like a space station, They are floating in the vacuum of space.

But the only difference is between the space station and space colony is, A space colony is intended as a permanent settlement or green habitat rather than as a simple station.

Space colony

The richest man in the world Jeff Bezos says Mars is not a place humans would be comfortable living. 

In other words, making an inhabitable planet into a habitable is very hard and long work, His ambition to build floating space colonies where people could in orbit, saying that the colonies would have excellent climates, with weather like “Maui on its best day, all year long.”

This is not a new idea, Fiction of space colony goes back to the second half of the 19th century. “The Brick Moon”, a fictional story written in 1869 by Edward Everett Hale, is perhaps the first treatment of this idea in writing.

In 1903, space pioneer Konstantin Tsiolkovsky speculated about rotating cylindrical space colonies, with plants fed by the sun, in Beyond Planet Earth. And there are many more people who write and discuss this idea.


As with any other idea, this idea also had some advantages, some real serious advantages.

Artificial Gravity

If we ever colonize any other planet smaller or bigger planet then eath then we will feel different gravity, but things not gonna look the same in space colonies. Unlike colonies on any other planet, space colonies are going to be human-made artificial habitats floating in the vacuum of space, which means we have much more control over an artificial habitat than a celestial object.

Artificial Gravity is not something from science fiction, it’s a simple way to generate gravity-like force, Imagine the wheel-shaped ships from films like 2001: A Space Odyssey and The Martian, imaginary craft that generates their own gravity by spinning around in space.

It’s not completely safe from an asteroid, but at least it will protect inhabitants from any natural disaster.

As you already know throughout the article, it’s an artificial habitat floating in space, which means humans can manually control the atmosphere that suits humans, which means humans living on space colonies will be much healthier than humans living on any planet.

4 Most Smartest Animal Colony in the Planet


Earth is home to multiple life forms and one among them is humanity. Humans are the main race in this whole world, and we are characterized by much more sophisticated social structures, yet we’re not talking about how clever humans are, but we’re looking at some of the Earth’s most intelligent animal colonies.

4. Elephants

Elephants are stunningly brilliant animals. They have the largest cerebrum of any land organism, with three times the number of neurons as humans. While vast numbers of these nerves remain to power the immense and adroit body of the elephant, on several occasions these creatures have shown their incredible mental abilities.

3. Dolphins

Dolphins still have a strong reputation for their intellect and are often compared to other intelligent animals such as elephants and humans.

Most dolphin species live in groups called pods made up of 2 to 30 dolphins as the number varies, but in certain places with plentiful food, many pods may form superpods of more than 1,000 members.

They’re fairly collaborative with each other, and they’re still a party hunter.

2. Orcas

The orca or killer whale is a toothed whale belonging to the tribe of ocean dolphins and is the largest member of the family.

Orcas are kind of social creatures. They live in small nuclear and extended families, which we call pods, clans, and cultures.

The mother of the orca is in the social heart. She and her children, including her grown-up sons, stay together for a lifetime.

1. Chimpanzee

Chimpanzee is one of the nearest people to humanity, and in certain scenarios, they have a very similar social system to us.

Chimpanzees are one of the great apes, and like all the other apes, they are intellectual, and chimpanzees have a social structure that is one of the most nuanced animals.

Chimps have a reputation for being vicious, but you must understand the evolutionary mechanisms that lead to their development.

It’s vital to remember that chimps are only acting in ways that are natural to them as a result of their evolutionary process. So, while their behavior may appear savage to us, it is only a result of their particular environment.

They are social animals who spend their lives in the company of their companions. This behavior might seem logical because they are the closest relatives to human beings, who are also highly social.
