The Brain Defense: Vets with head trauma, stress find mercy in court

Photo Illustration by Steve Ravenscraft. Not long after Kris Parson returned home from the war in Iraq, his girlfriend began calling the police to their house in Coon Rapids, Minnesota, a suburb about 15 miles north of Minneapolis. Then one night she called the police again. While he was being booked at the jail, Parson knew just whom to call. Hunter has developed a specialty in representing veterans charged with crimes outside the military justice system. Lawyer-Veteran Hunter is a veteran himself, having served four years in the Army, mostly as a sniper scout in the tension-filled demilitarized zone of Korea during the late 1980s. When he returned, he spent a few years in college not knowing what he wanted to do, went to law school and joined a corporate firm. After leaving that job, Hunter took on criminal cases and worked for the local public defender’s office. Brain network of psychopathic criminals functions differently. Many criminal offenders display psychopathic traits, such as antisocial and impulsive behaviour.

Brain network of psychopathic criminals functions differently

And yet some individuals with psychopathic traits do not commit offences for which they are convicted. As with any other form of behaviour, psychopathic behaviour has a neurobiological basis. To find out whether the way a psychopath’s brain is functionally, visibly different from that of non-criminal controls with and without psychopathic traits, we talked to Dirk Geurts and Robbert-Jan Verkes: researchers from the Donders Institute, the Department of Psychiatry at the Radboud University Medical Centre. Behold the Most Complicated Object in the Known Universe - The Leonard Lopate Show. Could US Military Brain Scans Screen Police for Racial Bias? Can functional magnetic resonance imaging (fMRI) brain scans and other technology currently being tested on soldiers in the US military be used to screen police recruits for hidden racist attitudes?

Could US Military Brain Scans Screen Police for Racial Bias?

The answer is a resounding YES! Departments all over the country should be paying attention because this is the future and it’s ready to use right now. It’s just one bi-product of “The Human Brain Project,” whose goal is to map and recreate the brain using super computers. The purpose is to advance the fields of neuroscience, as well as technology. That, of course, is not the goal of the military and DARPA (Defense Advanced Research Projects Agency) who are also involved as investors.

Neuroscience and Free Will (2) (Part One) Discoveries in neuroscience, and the science of behaviour more generally, pose a challenge to the existence of free will.

But this all depends on what is meant by ‘free will’. The term means different things to different people. ListMenziesFreeWill.pdf. This Device Brings “Brave New World” to Life. Opposition to racism used to be a political stance.

Now it has every marking of a religion, with both good and deleterious affects on American society. An anthropology article from 1956 used to get around more than it does now, “Body Ritual Among the Nacirema.” Because my mother gave it to me to read when I was 13, of course what I remember most from it is that among the Nacirema, women with especially large breasts get paid to travel and display them. Perceive this: The human brain controls alpha-band oscillation phase to effect temporal predictions. Standard models of perception are stimulus-driven, meaning that the external perceptual event drives the brain's perception-related activity.

Perceive this: The human brain controls alpha-band oscillation phase to effect temporal predictions

However, the tide may be turning: recent ideas suggest that our perceptual experiences and visually guided behaviors are influenced by top-down processes in the brain – specifically, the brain's predictions about the external world. Porn 'Addiction' Isn't Really Addiction, Neuroscientists Say. Porn "addiction" has been a subject of considerable debate among psychologists and in pop culture.

Porn 'Addiction' Isn't Really Addiction, Neuroscientists Say

Some argue that porn encourages sexual violence and harms relationships. Others say it may have a place in a healthy sex life. Addiction is not a disease: A neuroscientist argues that it’s time to change our minds on the roots of substance abuse. The mystery of addiction — what it is, what causes it and how to end it — threads through most of our lives. Experts estimate that one in 10 Americans is dependent on alcohol and other drugs, and if we concede that behaviors like gambling, overeating and playing video games can be addictive in similar ways, it’s likely that everyone has a relative or friend who’s hooked on some form of fun to a destructive degree. But what exactly is wrong with them? For several decades now, it’s been a commonplace to say that addicts have a disease. However, the very same scientists who once seemed to back up that claim have begun tearing it down. Psychosurgeons Use Lasers to Burn Away Mental Illness.

A brain surgeon begins an anterior cingulotomy by drilling a small hole into a patient’s skull. The surgeon then inserts a tiny blade, cutting a path through brain tissue, then inserts a probe past sensitive nerves and bundles of blood vessels until it reaches a specific cluster of neural connections, a kind of switchboard linking emotional triggers to cognitive tasks. With the probe in place, the surgeon fires up a laser, burning away tissue until the beam has hollowed out about half a teaspoon of grey matter. This is the shape of modern psychosurgery: Ablating parts of the brain to treat mental illnesses.

Which might remind you of that maligned procedure, the lobotomy. 'Exploding head syndrome' common in young people: Nearly one in five startled by loud, non-existent noises. Washington State University researchers have found that an unexpectedly high percentage of young people experience "exploding head syndrome," a psychological phenomenon in which they are awakened by abrupt loud noises, even the sensation of an explosion in their head. Brian Sharpless, a Washington State University assistant professor and director of the university psychology clinic, found that nearly one in five -- 18 percent -- of college students interviewed said they had experienced it at least once. It was so bad for some that it significantly impacted their lives, he said.

"Unfortunately for this minority of individuals, no well-articulated or empirically supported treatments are available, and very few clinicians or researchers assess for it," he said. A Common Link Among Female Criminals: Brain Injury. Nearly 40 percent of women in prison in Ontario, Canada, have suffered a traumatic brain injury (TBI), according to a study published this month in the Journal of Correctional Health Care. The study, the first to look at the rate of TBIs among prison populations in Canada, contributes to a growing body of evidence associating blows to the head with a multitude of long-term, negative health outcomes, from homelessness and substance abuse to risky behavior and incarceration.

In revealing the high rate of TBIs among people in prison, particularly among female inmates, the research team hopes to raise awareness of a widespread yet overlooked public health problem. "TBIs are common, and most are not associated with offending behaviors," said Dr. Coming Soon—Electronic Mood Control. I’m working on a story that’s almost due. It’s going well. I’m almost finished.
