How does brain think?

Billions of neurons communicate with each other via trillions of pathways called 'synapses'. The pattern of electrical activity that this creates is what gives rise to everything we do and think and how we feel. However, we understand but a handful of these patterns and how they relate to various states of consciousness and mental tasks . The biggest challenge neuroscientists face is decoding what these patterns mean and then inventing ways of manipulating them for therapeutic purposes.

What is the back of the brain?

The brain controls the human body.

I don't know if the answer above is supposed to be sarcastic, or just someone who doesn't know and wanted to add something anyway. That is an incredibly useless answer.

In part, the brain controls movement of all body parts, temperature, heart beat, interprets feeling and pain, breathing, when you sleep it regulates breathing and controls the heart, and does much more, but since I'm not a doctor, that is about all I know.

Why can you not remember the past?

You don't want to forget your past as there are so many valuable experiences good or bad that you have learned from that have come to shape your being. I realize you may want to forget one certain incident but instead of thinking you would like to forget it think of the situation and what you may have learned from it - what I mean is some things happen for a reason and others we create on our own, what could you take from the situation and apply or change for your future as to not repeat whatever it is that you would like to forget or maybe a behaviour you learnt maybe useful. Things are only as bad as we let them be and if you try to look at things from different angles - as they say if you get lemons make lemonade.

On a RWD vehicle the engine is mounted front to rear. Sitting in the driver's seat, the left side of the engine is on the left side of the car. On a FWD vehicle the engine is mounted sideways. Standing looking at the side of the engine where the transmission is connected, to your left is the left side of the engine. Normally the transmission is mounted on the driver's side of the vehicle, so the left side of the engine would be the side closest to the radiator.

Which is stronger the heart or the brain?

The heart has beauty, potential. It is what holds everything you love, and hate. It holds the memories, the good times. It holds the people you love, the things you like.

You have a strong heart if you can go through with anything and have pride in your soul! ~Jenn
