Ebbinghaus illusion
The Ebbinghaus illusion occurs when an optical illusion causes a stimulus to appear larger than its surroundings. Its appearance will depend on the size of the stimulus and what the surrounding objects perceive. The flash-lag effect which causes the objects to look similar later in time confirms size perception. Participants were shown two sets each of four identical surrounding discs at different times, depending on their position on the retina. A significant flash-lag effect was observed when the size of the central disks changed from one side of the retina to the other.

How does the brain control the functions of your body?
The brain communicates with other organs to ensure their cooperation. The brain controls everything that happens in your body. It tells the stomach to digest food, and the lungs to breath air. It also tells your legs and arms to move.
Your brain is made up of billions upon billions of nerve cells that are connected together in groups called neuronal groups. Neurons communicate by sending electrical signals, called action potentials, on axons. Every neuron has an outer cell membrane that surrounds its nucleus. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. The neuron is lit by an electric charge created by the movement of ions.
When a neuron is activated, neurotransmitters release chemicals into the space between it and the next neuron. Neurotransmitters are able to bind to receptors in the second neuron. This opens ion channels that allow ions to flow in and out. This causes the second neuron to fire too.
Neurotransmitter production occurs when a neuron in the presynaptic receives an impulsive signal from another. The impulse travels along the synapse connecting the two neurons. The transmitter binds to receptors on the postsynaptic neuron, triggering the firing of the postsynaptic neuron.
Neurotransmitters are important for communication within the nervous system. They coordinate brain activity among different parts.
What is the most mysterious area on earth?
Antarctica is the world's most mysterious place on Earth.
What is it that makes this place so interesting? Because it is unlike anything else on Earth.
It is remote and difficult to reach. It is not what you see.
These wild animals are also found in this natural wonder.
Let's look at how this extraordinary destination became so mysterious.
Antarctica: The South Pole
It is not known why Antarctica was called Antarctica. Some say it means "land on ice." Others think it comes from Greek mythology.
Antarktis, the Greek name for the island on which Zeus' twin brothers were conceived, was used in ancient Greece. According to legend, one of the twins was born in winter. This is why the word "antarctic" was chosen.
Others believe that the name is a combination of the Greek words anti and tropos which mean against and turn. This would mean that the land was turned away by the sun.
Whatever the reason Antarctica has held a special fascination for people, it is undeniable.
It is also the lowest, windiest continent, driest, and highest. It is too cold to support trees, plants, and animals.
Yet, the frozen desert is alive with life.
About 90 percent of all living things on Earth live here. Here are approximately 50% of all the animal and plant species in the world.
What is it that makes Antarctica so unique? Here, water freezes in ice rather that vaporizing into the atmosphere.
This causes large ice masses to rise above the ground.
These floating glaciers cover 80% of the continent. And they're growing larger every year.
So far, the Antarctic ice sheet has grown 60 feet since 1960.
If the melting continues, sea level could rise up to 200ft. It could result in massive flooding all over the world.
However, not all scientists believe this to be bad news. Some scientists believe that global warming can be beneficial. They believe that global warming will lead to melting ice sheets faster and floods that can flush toxic chemicals out of our soils and bodies.
Others, however, warn that this theory sounds almost like a plot for a science fiction film.
What dark secrets are there in Hollywood?
Hollywood is full secret societies. Some secret societies are cultlike groups that have strict rules and rituals. Other clubs are for people who share common interests.
Some of the most powerful organizations in the industry are even more dangerous. These include companies like the MPAA ("Motion Picture Association of America"), which determines film ratings. The RIAA ("Recording Industry Association of America") sets music licensing fees.
Many unions and guilds represent actors, directors writers, producers, and others. The majority of major television networks and movie studios are owned by large corporations.
It doesn't matter how secretive a group might seem, someone somewhere knows what they are doing. But that doesn't mean we should fear them.
Instead, embrace them. Because they give us information that allows us to make better decisions.
These people tell us what movies and songs will succeed, and which books will sell best.
They allow us to make informed decisions about what we buy, watch and listen to.
We can trust them so we can ignore their advice when it doesn't suit our taste.
They are more powerful than ever because we chose to ignore them. They are the supreme arbiters of taste.
They can be ignored if you don’t like what they have to say.
Now let's take a look at some lesser-known yet very real Hollywood secret society.
And you'll understand why they're so crucial.
