The human brain is a delicate, complex collection of neurons, glial cells, electricity, and hormones. According to research published by Karger, the adult human brain consists of 86 billion neurons. Think that’s impressive? Scientific American reports that glial cells outnumber neurons by as many as 50 glia for everyone one neuron.

Neurons are the primary unit of our brains and nervous system. They are responsible for sending and receiving sensory input, in addition to controlling our muscles. Furthermore, neurons translate these messages into electrical signals and relay them from one neuron to another.

Hormones are chemicals produced by cells in one part of the body that travel through your bloodstream in order to conduct these messages to other areas of the body. They regulate our behaviors, such as our emotions, sleep and wake cycles, our appetite, and many other bodily functions.

There are many different hormones including adrenaline, insulin, estrogen, testosterone, serotonin, dopamine, oxytocin, among others.
