Ebbinghaus illusion
The Ebbinghaus illusion occurs when an optical illusion causes a stimulus to appear larger than its surroundings. Its appearance depends on the perceived size of the surrounding objects and the retinal size of the stimulus. The flash-lag effects, which cause objects to appear similar at later times, confirms that size perception. In this study, participants were shown two sets of four identical surrounding disks at different timings relative to their locations on the retina. It was evident that the size of the central discs on one side of the retina changed significantly, creating a flash-lag effect.
FAQ
How does your brain control your body's functions?
To ensure that they work together, messages are sent by the brain to other organs. Your brain controls all that happens in your body. It tells your stomach how to digest food and your lungs how to inhale oxygen; it also tells your arms, legs and feet to move.
Your brain is made up billions of nerve cell networks connected in groups known as neurons. Neurons communicate with each other by sending electrical signals called action potentials on axons. Every neuron has a cell wall around its nucleus. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. Ion movement is what causes the neurons to fire.
Neurotransmitters are chemicals released when a neuron fires. Neurotransmitters bind to receptors on the second neuron, opening ion channels so ions can pass in and out of the channel. As a result, second neuron fires as well.
Neurotransmitter release occurs when the presynaptic neuron receives an impulse from another neuron. The impulse travels along the synaptic pathway that connects both neurons. The transmitter binds directly to the receptors in the postsynaptic nervous neuron, and triggers the firing.
For communication within the nervous systems, neurotransmitters are essential. They also help coordinate activity between different parts of the brain.
What dark secrets do Hollywood have?
Hollywood is filled with secret societies. Many secret societies are cult-like and follow rigid rules. Others are just clubs for people with common interests.
There are other nefarious entities that have a significant influence on the industry. Companies such as the MPAA, which determines film ratings, or the RIAA (Recording Industry Association of America), that set music licensing fees, are examples of these.
Numerous unions or guilds also represent producers, writers, actors, etc. Most major movie studios and television networks are owned by large corporations which own these various organizations.
The fact is that regardless of how secretive any group may be, someone somewhere knows exactly who they are. We shouldn't fear these people.
Instead, we should embrace them. Because they give us information that allows us to make better decisions.
These experts tell us which movies are most likely to succeed, which songs will be in demand, and what books will sell the best.
In short, they help us decide what we'll buy, watch, read, and listen to.
Because we can trust them, we can ignore their advice when it conflicts with our tastes.
We choose to ignore them and they become even more powerful. They are the ultimate judges of taste.
You are free to ignore their messages if that bothers you.
Now let's take a look at some lesser-known yet very real Hollywood secret society.
You can see why they are so vital.
Which is the most secretive city in the world?
You might be surprised at the answer. It may even make it uncomfortable, as it challenges our perceptions of reality and our lives. But there is a reason why this place exists. And it is not what you would expect.
It was called the City of God by ancient Greeks. In the Bible, it was known as the City of Destruction.
It is called Kashi (Kashmir in India). It's known in Russia as Novgorod.
It's called The Town That Has Disappeared here in America.
A small community of 1200 people in western New York State vanished. It was abandoned without any remains, including no bodies, cars, or houses. The only thing that survived was a road sign, which pointed to its former location.
This tiny community disappeared without leaving any clues as to where it went or when. Some claim the earth swallowed it. Others claim that a meteorite hit destroyed it. Some believe that it was taken by aliens.
Regardless of what happened, residents of this once-thriving town are certain that their town won't be forgotten forever. They had just moved to another town.
Even a website exists to help track down the disappearances of the lost city Zugspitz.
The question is, where did this place go? It's in Switzerland.
Zugspitze is located on the border between Germany and Austria. A huge lake, Lake Zugspitze, is located just beyond the summit.
It has always fascinated my that so many towns have disappeared but others still exist. Why do some disappear while others survive? I decided that I would investigate.
I was interested in learning more about these mysterious towns that are disappearing. What causes a town to disappear? How does one place go extinct?
It turned out that there are many theories about disappearing towns. One theory is that a city disappears after all buildings have been demolished. Another theory states that the town simply moves to another location. Another theory suggests that the town has never existed.
Theories aside, the fact remains that dozens of towns around the globe have been swallowed up by the ground. This video explores the history of these towns and examines their current state.
What is the most mysterious place on earth?
Antarctica is the most mysterious continent on Earth.
Why is this place so amazing? It is unlike any other place on Earth.
It is remote and difficult to reach. There is much more to this place than meets the eyes.
You will also find some of the oddest wildlife species in this natural wonder.
Let's look at how this extraordinary destination became so mysterious.
Antarctica: The South Pole
No one knows exactly why Antarctica was named Antarctica. Others believe it means "land with ice". Others think it comes from Greek mythology.
In ancient Greece, Antarktis was the name given to the island where Zeus' twin brothers were born. According to one source, one of the twins was conceived in winter. Hence, the word antarctic.
Others believe that the name comes from the Greek words anti meaning against and tropos meaning to turn. This would be land turned away form the sun.
Whatever the reason, Antarctica has always held a special fascination for people.
It is the highest, coldest, windiest, dryest, and most populated continent. Because it is so cold, there aren't any trees, plants or animals.
Yet, the frozen desert is alive with life.
Here, 90 percent live of all species of living things. There are about 50% of the world's animal, plant and plant species.
What is it that makes Antarctica so unique? Here, water freezes and becomes ice instead of evaporated into the air.
This results in large masses of ice floating above the ground.
These floating glaciers cover over 80%. They are growing in size every year.
The Antarctic Ice Sheet has grown 60 feet in the past 60 years.
The sea level will rise up to 200 feet if melting continues. This could lead to massive flooding across the globe.
This is not necessarily bad news. Some scientists suggest that global warming could actually be good for us. They suggest that rising temperatures could cause ice sheet melt faster, leading to floods that flush out toxic chemicals from soil and bodies.
Others cautioned that this theory sounds too science fiction.
