Stage 1: Lust
Phenylethylamine
Norepinephrine
Dopamine
Oxytocin
Testosterone

This is driven by the hormones hormones testosterone and oestrogen.
Dopamine is created in the brain and adrenal glands enhance the release of testerone.

Neurotransmitters
the chemicals which allow the transmission of signals from one neuron to the next across synapses
synapse- the structure that permits a neuron or nerve cell to pass an electrical or chemical signal
oxytocin
Oxytocin
Main love hormone
"cuddle hormone"
Oxytocin levels go up when you touch someone
peptide (a compound consisting of 2 or more amino acids)
Serotonin
Helps regulate mood, appetite, sleep cycle, etc.
Responsible for peace and calm
Lowers in the second phase of love
Because of the drastic fall in serotonin, anxiety is heightened
Phenylethylamine
Known as the "Love Drug"
more alert
gives us a sense of well being and contentment
Serotonin
Vasopressin
Endorphins
Also know as the body's natural painkillers
block pain
responsible for our feelings of pleasure
