Le neurobiologiste qui a découvert qu'il était psychopathe Je vous avais déjà résumé les grandes lignes du dernier cours de Parlons cerveau IV intitulé « Neuroscience et libre arbitre » qui aura lieu ce mercredi 27 novembre (voir le premier lien ci-bas). En cherchant un article récent pour illustrer ce propos, je tombe sur cette histoire digne d’un titre de livre d’Oliver Sacks. Celle d’un chercheur en neuroscience qui découvre, en analysant les résultats d’une de ses expériences en imagerie cérébrale, que son cerveau a toutes les caractéristiques classiques de celui d’un… psychopathe ! L’histoire remonte à 2005 alors que James Fallon analysait les PET scans de milliers de sujets pour en distinguer des patterns d’activité typique de schizophrènes, dépressifs , psychopathes et personnes souffrant d’Alzheimer . Plusieurs personnes de sa famille, y compris lui-même, avaient participé à cette dernière étude. C’est sur l’une de ces images de cerveau d’un membre de sa famille que Fallon s’arrête, pétrifié.

Weird Wired Science Austrian physician Franz Joseph Gall sought to understand the mind of murderers and other criminals by feeling the outside of their skulls. This practice, which he first used in 1796, later came to be called Now largely discredited, it turned out that neither Gall nor anyone could systematically link the bumps and lumps on the head to any regular patterns of behavior, criminal or otherwise. Psychologists no longer need to use scalp massages as diagnostic tools. They can now look at what's happening inside the skull using one of several types of brain scans. The most successful of these methods is the magnetic resonance imaging (MRI) brain scan, particularly the functional MRI (or fMRI). Patients are placed within a scanning device that causes nuclei within the cells to produce a rotating magnetic field detected by the scanner. Brain scans are clearly an advance over phrenology, but they also have their limitations. The "wow" factor is only part of the story.

Scientists study serial killers to understand what lies behind their crimes They are fascinating and terrifying in equal measure, but for many people understanding what motivates serial killers to murder many times over can be difficult to grasp. Psychologists and neuroscientists are starting to build up a picture of the disturbing minds behind some of the most shocking crimes to have come to light in recent decades. They have discovered surprising similarities between these mass murderers and have even found evidence that suggests a genetic abnormality that may act as a trigger. While most people may be quick to dismiss serial killers as simply monsters, scientists are now attempting to understand what causes them to commit mass murder by studying their brains and their DNA. Dr Helen Morrison, a forensic psychiatrist based in Chicago, has studied and interviewed 135 serial killers, according to an infographic compiled by the website Best Counseling Degrees.

Brain waves can cut braking distances, researchers say 29 July 2011Last updated at 09:44 By Judith Burns Science reporter, BBC News Volunteers wearing EEG caps used a driving simulator Tapping into drivers' brain signals can cut braking distances and avoid car crashes, according to scientists. Researchers at the Berlin Institute for Technology attached electrodes to the scalps of volunteers inside a driving simulator. The system detected the intention to brake, and cut more than 3m (10ft) off stopping distances, the team report in the Journal of Neural Engineering. The team's next aim is to check the system in a series of road tests. The 18 volunteers were asked to keep 20m (66ft) behind the simulated car in front, which braked sharply at random intervals. Scientists used a technique called electroencephalograhy (EEG) to analyse the drivers' brain signals. The system was able to pinpoint the intention to brake 13 hundredths of a second before the driver applied pressure to the brakes. "We were surprised it is so predictive. 'Point of no return'

Le retour du criminel né ? Après de brillantes études de psychologie à Oxford et à York, Adrian Raine émigre en Californie en 1987. Deux raisons motivent ce choix, explique-t-il avec la spontanéité qui le caractérise : le climat… et la plus grande accessibilité des criminels à des fins de recherche que dans son Angleterre natale. « Neuro-criminologue » autoproclamé, l’universitaire britannique séduit par le soleil californien est surtout le premier chercheur à avoir eu l’idée de « scanner » le cerveau de criminels. En 1994, il utilise le PET scan* pour enregistrer l’activité cérébrale de 41 prisonniers américains. Aujourd’hui professeur de criminologie à l’université de Pennsylvanie, Adrian Raine clame invariablement sa théorie d’un fondement biologique du crime. Génétique de la violence La marque de Caïn ? Mais Raine ne s’en tient pas à la génétique. Il faut concéder une chose à Adrian Raine : sa thèse n’est pas manichéenne au point de rejeter l’influence de l’environnement social sur la criminalité.

Gaslighting The term owes its origin to the play Gas Light and its film adaptations, after which it was coined popularly. The term has been used in clinical and research literature.[3][4] Etymology[edit] Clinical examples[edit] Sociopaths frequently use gaslighting tactics. Some physically abusive spouses may gaslight their partners by flatly denying that they have been violent.[4] Gaslighting describes a dynamic observed in some cases of marital infidelity: "Therapists may contribute to the victim's distress through mislabeling the woman's reactions. [...] Gaslighting may also occur in parent–child relationships, with either parent, child, or both, lying to each other and attempting to undermine perceptions.[9] Furthermore, gaslighting has been observed between patients and staff in inpatient psychiatric facilities.[10] Introjection[edit] Resisting[edit] In the media[edit] The 2000 Steely Dan album Two Against Nature includes a song entitled "Gaslighting Abbie".

Smart Guide to 2012: Mapping the human brain - health - 21 December 2011 The Human Connectome Project aims to map the large-scale connections of 1200 human brains and will start reporting data in late 2012 Read more: "Smart Guide 2012: 10 ideas you'll want to understand" Since the 19th century people have speculated that the essence of human identity is stored in the connections between our neurons. Today we have the technology to find out if this is true. Until now, most of what we know about the brain has been based on observations of what happens when different regions are damaged, or on imaging techniques like functional MRI that show which areas are active but tell you little about how they relate to one another. Not knowing how these different regions interact is like trying to work out how a telephone network works without knowing where all the wires go. With 100 billion neurons, each with around 10,000 connections, mapping the human brain will be no easy feat, and charting every single connection could take decades.

Do serial killers have an extra chromosome? – Scientific Scribbles There is no such thing as a “killer gene”, but research is revealing genetic tendencies towards violent behaviour. Face of a serial killer. Photo Credit: Curtis John via Flickr [BY-ND-2.0], 2009. It’s a slippery, discreet mutation, after all we don’t see entire families of serial killers Parents of children, who have grown up to be serial killers, have reported that their child was markedly different from their other non-violent siblings. Cropped image of blood in water. Nature vs. Environment alone cannot explain deranged behaviour as too many abused and neglected children grow up to be law-abiding citizens. Nature vs. Chromosomal abnormalities in serial killers According to Dr Helen Morrison, an American forensic psychologist and writer, chromosome abnormality in serial killers begins to express itself during puberty. Conversely, serial killer Richard Speck’s had an extra Y chromosome, which his lawyers argued was the cause of his violent crimes. Nervous System. Causes for killing
