Mechanistically, the stress response has two major neuroendocrine components. The first is a rapid activation of the sympathetic nervous system whose endpoint is the release of catecholamines into the blood from the chromaffin tissue (the teleostean homologue of the adrenal medulla: Reid et al. 1998, Gallo & Civinini 2003). This is coupled with a slower endocrine cascade that encompasses three tiers of organisation: the hypothalamus, the pituitary and the interrenal tissue (the homologous tissue to the adrenal cortex: Gallo & Civinini 2003).
