How Neurotransmitters Work

by Thomas Hall

Chapter 1: Introduce your fight or flight response So what exactly is stress? What is anxiety?Both of these are psychological and physical states, caused by the release of certain chemicals in the brain and body. These occur in response to physical or psychological stimuli and have adaptive functions that help us survive longer.For example, this can happen if you fall from a height, or if you find a threat in your surroundings. In this regard, the "significant network" of your brain will direct your attention and trigger the release of the correct chemicals.These chemicals are composed of neurotransmitters and hormones, • Adrenaline (epinephrine)• Norepinephrine (Norepinephrine)• Dopamine• Cortisol• Glutamic acid• Testosterone• SerotoninNeurotransmitters such as dopamine are chemical "signals" released during synaptic transmission. They are stored in "vesicles" at the end of each neuron and released during communication to instruct brain cells on how to behave (regulate attention, memory, and consciousness).At the same time, hormones are mainly released into the blood, which has a wider and longer lasting effect on the body and brain. Some hormones can also act as neurotransmitters, thereby affecting our mood, concentration and memory.
