Neurotransmitters are chemicals that transmit signals across a synapse‚ a structure that permits to pass electrical or chemical signal to another cell from one neuron to another. Neurotransmitters are synthesized from converting substances that are readily available to the body such as amino acids‚ which are available from food and only need some converting into transmitters.

Peripheral Vision Peripheral vision is also known as Side vision. It is the ability to see objects and movement outside of the direct line of vision. Peripheral vision gives you the ability to pay attention to something even if your front vision is focus on something else.
