Thank you very much for the excellent  resources.  

Thanks Mahdi! Nice to hear that my help is adequate. Because always, along with your positive logic, there is a nameless man, who does not like any positive action. Perhaps so nameless man calls on to help in a situation of excess receive scopolamine.

I inject intraperitonely  o.7 mg/ kg scopolamine to rats (3 months old). but in some articles I notice that some researchers increase that dosage to 1.0 or even 1.5 mg

I usually inject scopolamine1.0 mg/kg ip to mice (2 to 3 months) to induce memory impairment and it always works when testing with diferrents paradigmes.
