What would happen if we didn't have a brain?

In short term there would be no life, there thats a simple answer. But thats not fun (because I searched it up on google). 

The body has to have a brain that is working, you can not function without it. 

Different parts of the brain control different parts of the body. Did you know that the brain controls the opposite side of the body? Surprisingly the right hemisphere controls the left side of the body, and the left controls the right side of the body. 

There is a part of the brain called the temporal lobe it controls the memory and also memory of noise's that you recognize. (e.g somebody opening a packet of chips and you hear the noise and know that it is chips before you see it). 

The brainstem is one of the most important parts that make up the brain. It is important because it connects the brain to the spinalcord. The spinal cord is like a extension cord to your brain. It sends a message for your body to move and also sends a message up your spinal cord to your brain that it feels sensations these are nerves from the spinal cord.

So in long term there still be no life Since the brain controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there still can't be life without it.

Don't you think the brain is an incredible part of the human body. Signals in the brain hop from neuron to neuron at a speed of roughly 390 feet per second, thats fast.

What do you think of the brain?
