Key result
Intracerebroventricular injection of salmon calcitonin reduced pain in the formalin test (p<0.05) by increasing monoamine concentrations in the periaqueductal gray area.
Why the study?
Salmon calcitonin receptors in brain areas such as the periaqueductal gray matter modulate pain, prompting exploration of how intracerebroventricular injection affects pain response and monoamine levels.

Intracerebroventricular salmon calcitonin reduces pain in a rat formalin model by increasing monoamines and their metabolites in the periaqueductal gray area.
Rahimi et al. (2019) studied Pain (n=45). Salmon calcitonin was evaluated on Pain behavior in the formalin test (p=<0.05). Intracerebroventricular injection of salmon calcitonin reduced pain in the formalin test (p<0.05) by increasing monoamine concentrations in the periaqueductal gray area.
