Joni?

Ei.

Hän on ollut elämästäni jo tovin poissa enkä kuulunut hänen tulevaisuudensuunnitelmiinsa.

 

Ehei

Älä vastaa toisen puolesta.

 

Don't answer for someone else.

Just let this next (text) go from your eyes to your mind. You should (all) read this
multiple times if something doesn't open up right away. When we look at text (eg this text on a screen), our eyes and brain cooperate in synergy during a process that enables reading and understanding of the read text. This chain of action can be divided into several different steps: In the first step, our eyes receive light. When light is reflected from a screen, for example, it is refracted through the cornea and lens of our eyes, and from there ends up on our retina. This is also individual how it folds. Depending on the structures of the human eye. Our retinas have special cells that react to light: they are called rod cells. Rod cells help us see in the dark, and pin cells, on the other hand, help us recognize colors and shapes.

These different cells convert the light into electrical signals in our brain.
After the retina has converted the light into electrical impulses, these signals travel along the optic nerve to our brain. The optic nerve acts as a message sender that takes information to the visual area of our brain. In our brain, signals first arrive at the visual cortex, which is located at the back of the head. This part of the brain helps us form the basic features of the environment, such as shapes and colors. When the visual cortex has processed the basics, the signals are then transferred to other parts of the brain, such as the temporal lobe and the cerebral cortex. In these areas, our brain understands the meaning and language of the text. When the brain has processed and understood the meaning of the text, awareness is the next thing that arises (or should be). This stage also includes reactions and remembering.
