Q

Teoria neurogena

A

Neuronii din hipocamp si aria prefrontala sunt distrusi de stres (cortizon).
Prin stimulare Gs cu serotonina si noradrenalina se activeaza CREB (cAMP response element-binding protein) care produce BDNF (brain derived neurotrophic factor) ceea ce determina multiplicarea neuronilor
