Aggression imprinted in our brain

Aggression is a means of communication in which one party tries to impose its own ideas and feelings using emotional force or physical strength and neglecting the needs of the other individuals.

Current research published in the journal ‘Biological Psychiatry’ shows the crucial role played by serotonin in enabling people to control their aggressive impulses. The study from the University of Cambridge used only healthy volunteers, whose levels of serotonin fluctuated according to their daily diet. Certain foods, such as chocolate, bananas and turkey help regulate the serotonin level.

In given situations, a lower level of the neurotransmitter indicated a harder to control aggressive behavior. Dr Luca Passamonti, co-first author of the study said: ‘Although these results came from healthy volunteers, they are also relevant for a broad range of psychiatric disorders in which violence is a common problem. (…)We are hopeful that our research will lead to improved diagnostics as well as better treatments. (…)’
