The animals were divided into two groups according to the diet used: nourished group¾ the rats received the control diet with 23% protein during the life; and malnourished group¾ the rats had its mothers submitted to diet with 7.8% protein during suckling. At 120 days of age, each group was sub-divided according to the treatment: acute ¾ consisting a single i.p. injection of saline solution or 20-mg/Kg citalopram; chronic ¾ consisting the single injections (1 per day during 14 days) of saline or 20 mg/Kg citalopram. The acute or chronic treatment with SSRI reduces aggressive response in nourished rats, but not in malnourished ones. Thus, the malnutrition during the critical period of brain development seems to induce durable alterations in the function of the serotoninergic neurotransmission
