to exhibit such behavior. Studies of identical twins have frequently shown that if one twin exhibits aggressive behavior, the other often does so as well. Aggression may also have a neural basis; aggressive behavior has been produced in animals through electrical stimulation of parts of the brain...
The hypothalamus appears to be involved in this inborn reaction pattern: electrical stimulation of part of the hypothalamus triggers stereotypical aggressive behaviors in many animals. In people, however, whose brains are more complex, other brain structures apparently moderate possible instincts. An ...

Direct connections link part of the brain’s frontal lobes – very large in humans, and central to complex social behaviors including aggression – to the amygdala (which also receives sensory information from the cortex). Nerve bundles in turn link the amygdala to the hypothalamus, generating hor...
part of the brain. Serotonin is the only neurotransmitter that is able to do that. The prefrontal cortex is an organizational part of the brain. If there is an injury in that area one of the outcomes is impulsive, uncontrollable, and violent behavior. For teens, the best serotonin source ...

Testosterone is blamed for sex drive and aggression, but it also appears to be critical for telling the brain "enough!" when it comes to those behaviors. A molecule called TRPM8 (pronounced trip-M-8) embedded in the surface of some cells seems to be resp
aggression in mice to a distinct part of the hypothalamus, the brain region that controls body temperature, hunger, sleep, and levels of many hormones. This key part, the ventrolateral part of the ventromedial hypothalamus, or VMHvl, is located on the underside of the hypothalamus in mice and...
These are associated with a different part of our brain from logical thinking—and often seem to ‘switch off’ the thinking part. When you feel these sensations, it is worth taking a deep breath, and consciously applying your brain to the situation before responding. There is more about ...
