Structure of your brain
There are billions of neurons in the brain. These neurons are small cells that have tendril-like extensions that reach all areas of the brain. You can create new neurons, destroy old ones and modify existing ones.
These changes are triggered by your experiences. Neurons in the brain form memory and are responsible for the thoughts we have in our heads. Electrical impulses fire through the neurons and are signals that command your body to feel and act in a certain way. Neurons are interconnected and if two neurons fire at the same time frequently, they have a connection. Thus, if one neuron fires, the others are likely to fire as well, depending on the strength of the connection between them. You have groups of neurons in your brain that are connected and are responsible for specific behaviors. It is possible for a single neuron to reach from one end of your brain to the other. So when you experience something in your life, some of your neurons are activated depending on your memory and your understanding of the situation.
If there is a strong connection with other neurons, these will also fire. These connections are formed throughout life. The end result of certain neurons firing together is an emotion. Neurons have synapses that they use to communicate. There are neurotransmitters that include chemicals that are released into the surrounding cells.
