What is brain made of?

The brain as a radiator
Around 170 BC, Roman physician Galen suggested the brain’s four ventricles (fluid-filled cavities) were the seat of complex thought, and determined personality and bodily functions. This was one of the first suggestions that the brain was where our memory, personality and thinking reside.

What is brain simple words?
The brain is the part of the body which lets animals make sense of things. It gets input from sense organs, and changes behavior in response to this information. In humans, the brain also controls our use of language, and is capable of abstract thought. The brain is the main control centre of the whole body.

The brainstem is located in front of the cerebellum. Think of the brainstem like a computer hard-drive. It is the body’s main control panel and is responsible for conveying messages between the brain and other parts of the body. The cerebrum, the cerebellum and the spinal cord are all connected to the brainstem.

The results indicate that although pain is rare in dreams, it is nevertheless compatible with the representational code of dreaming. Further, the association of pain with dream content may implicate brainstem and limbic centers in the regulation of painful stimuli during REM sleep.
Why is the brain GREY?
In contrast, gray matter is mostly neuron cell bodies and non-neuron brain cells called glial cells. These glial cells provide nutrients and energy to neurons. … Because these cells are not surrounded by white myelin, they take on the natural grayish color of the neurons and glial cells.
What Color Is A Mirror?
As a perfect mirror reflects back all the colours comprising white light, it’s also white. That said, real mirrors aren’t perfect, and their surface atoms give any reflection a very slight green tinge, as the atoms in the glass reflect back green light more strongly than any other colour.
