Researchers examined oxytocin neurons in rats after systemic or intranasal Melanotan II exposure, using receptor-blocking comparisons.
What the researchers measured
Neuronal activation markers, electrical firing, and local oxytocin release measured by microdialysis were examined.
How to read this evidence
Researchers studied cells, isolated tissue, or animals. These experiments can help explain a mechanism, but do not establish benefits or safety in people. Human cells grown in a laboratory also belong in this category.
Results in context
Increased neuronal firing did not mean increased local oxytocin release, and routes differed. These measurements do not demonstrate improved human social behavior.
What this does not establish
Neuronal activation is not equivalent to hormone release or a demonstrated human behavioral benefit.
