Good question Debbie. Neuropsychologists think that the neural activity found in lab mice and other animals is a close approximation of the brain circuits found in humans. However, the mechanisms involved in adaptive and pathological aggression are not understood very well. Neurotransmitters like dopamine, serotonin, and GABA have been shown to have both positive and negative affects on aggression depending on what brain region is under investigation. Much work is needed.
