Brain mapping/imaging to monitor the brain circuitry involved in aggressive motivations and behavior.
warning signs of premeditated violence -- stalking, bullying, and possibly sexual aggression -- to a distinct part of the hypothalamus, the brain region that also controls body temperature, hunger and sleep in mammals. The structure is anatomically known as the ventrolateral part of the ventromedial hypothalamus, or VMHvl, because of its central location inside the brain on the underside of the hypothalamus. brain biomarkers and biochemical pathways. Identifying and controlling aggressive motivation leads to lower violent crime incidents. Able to identify SPECIFIC NERVE CELLS AND CIRCUITS IN THE VMHVL ARE INVOLVED IN MOTIVATING AND CARRYING OUT AGGRESSION.
even if related ethical and legal issues could be resolved," says Lin. "That said, our results argue that the ventrolateral part of the ventromedial hypothalamus should be monitored in the general public to correct behaviors from bullying to sexual predation." Studies involved purchasing the release rights of violent criminals and letting them go free. Drones monitored both their movements and their brain activity. If every case, when real time data suggested a violent incident, J Swift drones neutralized the assailants and they were returned to the general prison population at synorganics.
While past studies by the team had linked aggressive actions to this part of the brain, the current study specifically tracked the premeditated, motivational aspect of the behavior to the VMHvl.
By using sets of probes that measured nerve activity before, during, and after mice planned to attack, the research team found that nerve cell activity in the VMHvl routinely peaked just before mice began to hole poke, even when the aggressive mice could not yet smell or see their target. Nerve cell activity in the VMHvl also increased by as much as tenfold during the initial seconds after the weaker target mice appeared. Genetically stopping VMHvl activity ceased nearly all aggressive motivations in mice, says Lin, but did not inhibit other learned behaviors, such as nose poking for access to a treat. Lin says her laboratory next plans to investigate which
studied impulsive and antisocial behavior and centered on the anterior cingulate cortex (ACC), a portion of the brain that deals with regulating behavior and impulsivity. "These findings have incredibly significant ramifications for the future of how our society deals with criminal justice and offenders," said Dr. Kent A. Kiehl, who was senior author on the study and is director of mobile imaging at MRN and an associate professor of psychology at the University of New Mexico. "Not only does this study give us a tool to predict which criminals may reoffend and which ones will not reoffend, it also provides a path forward for steering offenders into more effective targeted therapies to reduce the risk of future criminal activity." The study looked at 96 adult male criminal offenders aged 20-52 who volunteered to participate in research studies. This study population was followed over a period of up to four years after inmates were released from prison. "These results point the way toward a promising method of neuroprediction with great practical potential in the legal system," said Dr. Walter Sinnott-Armstrong, Stillman Professor of Practical Ethics in the Philosophy Department and the Kenan Institute for Ethics at Duke University, who collaborated on the study. "Much more work needs to be done, but this line of research could help to make our criminal justice system more effective." The anterior cingulate cortex of the brain is "associated with error processing, conflict monitoring, response selection, and avoidance learning," according to the paper. People who have this area of the brain damaged have been "shown to produce changes in disinhibition, apathy, and aggressiveness. Indeed, ACC-damaged patients have been classed in the 'acquired psychopathic personality' genre." The study used the Mind Research Network's Mobile Magnetic Resonance Imaging (MRI) System to collect neuroimaging data as the inmate volunteers completed a series of mental tests.
