Chemicals in Brain

Every reaction there involves a chemical even though in water(H2O). Let’s know about the chemicals released by the brain and their chemicals reactions to make us feel and express different kinds of emotions.

There are some chemicals identified in our human body. They are,

Serotonin
Dopamine
Glutamate
Norepinephrine

Serotonin

You probably already know that serotonin plays a role in sleep and in depression, but this inhibitory chemical also plays a major role in many of your body’s essential functions, including appetite, arousal, and mood. Many antidepressants target serotonin receptors to improve your mood and lessen depressive symptoms.

Interestingly, most of your serotonin is stored in the intestine, and this chemical may play a role in digestive functioning as well.

Dopamine

Dopamine controls many functions, including behaviour, emotion, and cognition. This chemical also communicates with the front part of your brain, which is associated with pleasure and reward. On the positive side, it helps motivate you to work toward achieving a reward. However, many illegal drugs also target dopamine receptors, contributing to drug and alcohol addiction. Because dopamine is related to movement, low levels have also been linked to Parkinson’s disease.

Glutamate

This is the most common excitatory neurotransmitter, found throughout your brain and spinal cord. Glutamate has many essential functions, including early brain development, cognition, learning, and memory.

Norepinephrine

This chemical, also called noradrenaline, can sometimes act as a hormone as well. Its primary role is part of your body’s stress response. It works with the hormone adrenaline to create the “fight-or-flight” feeling. Norepinephrine may also be used as a drug to raise or maintain blood pressure in certain illnesses.

WHY ATLANTIC AND PACIFIC OCEAN ARE NOT MIXED?

Nearly 72% of the earth is filled with water and it is present with different names- oceans, seas, rivers. Why are they named differently? There are five oceans namely Artic ocean, Atlantic Ocean, Pacific Ocean, Indian ocean and Antarctic ocean . All the oceans are different in their physical and biological character called ocean clines. When we look at the Atlantic and Pacific Ocean junction, they do not mix. Is there any invisible Wall in between them? Many scientists have conducted research to solve this mystery. The Atlantic and Pacific Ocean have different chemical composition. The salinity of the water in the Atlantic Ocean is five times more than the Pacific Ocean. The density of water is also different, so even marine animals in Atlantic Ocean will not go to the Pacific Ocean. They cannot survive in other oceans. Atlantic and Pacific Ocean meet at Cape Horn. The narrow straight line formed by the water bodies is called Drake Strait. The Pacific Ocean is ...

How did fruits get their names?

There is a variety of fruits in today's world. Each fruit has a name and the names are derived from foreign languages - modern and ancient. Some of these fruits have names that don't go with the fruit also. The name gooseberry has nothing to do with geese. It was originally called gorseberry. 'Gorse' in Saxton (a language spoken by early germanic people) means 'rough'. This fruit grows on a rough or thorny shrub. Just like the gooseberry, the fruit strawberry has no connection with straws. Strawberry is the changed name of 'strayberry'. The strawberry runners stray in all directions and hence the name. Peaches have been around for thousands of years. This fruit made its way to Europe when the Romans were around. The Romans called it 'persicum' meaning 'Persian apples. It was traded by the Persians during that time. The national fruit of New Zealand kiwi was found in China. In other countries, it was called Chinese goo...

In 1983, The market price for this phone is $3,995. In 1930, Travelers could place phone calls from and to ocean liners in the middle of the Atlantic Ocean. The process was driven by Marine VHF Radio and cost $7 a minute. In 1984 Motoro...
