Understanding neurotransmitters and hormones is a major part of the biological level of analysis and understanding human behavior in general.
For example, the amount of testosterone in one’s body is the #1 correlative indicator regarding whether or not they’ll serve time in prison!
The three Major Neurotransmitters we’ll study are:
We’ll first address ACH through investigating its role in memory. Add this study to your individual “study guide to studies” The template of which is linked below:
Ach and its role in memory study by Antonova et al. (2010). This study also works for an ANTAGONIST as Scopolamine was used as an ACH antagonist:
Love as a drug? Helen Fisher on Dopamine and the Addiction of love:
In Laymen’s Terms:
Now, consider the above in relation to this Scientific American Post on Cocaine? What are the similarities between being in love and being addicted to drugs?
Hormones are similar to neurotransmitters in that they activate cells in our body. Specifically however, a hormone is a long distance chemical mediator that is secreted by an endocrine gland into the blood which is transported to target cells; whereas a neurotransmitter is a short distance messenger that is active in the synaptic cleft of neurons.
The Hormones we’ll be examining are Oxytocin, Testosterone and Adrenaline.
OXYTOCIN–“The Cuddle Hormone”
Oxytocin is famously referred to as the “cuddle hormone” and made famous by a variety of different research.
Read the summaries of research below:

Oxytocin as facilitating “spontaneous maternal behavior” in Prairie voles. Also, when blocked, maternal behavior stops…Young et al 2006

Testosterone–“The Aggression Sex Hormone”
Read the two pieces below. One is an abstract regarding a correlational analysis of testosterone levels of violent offenders in prison and the other is a Psychology Today article summarizing much of the research on the subject. Both are of high value:
