Under the direction of company president Justin Hall, Logistics Planning Services' charitable initiative LPS for Vets will hold their Charity Golf Classic Saturday, June 13, 2015 at the White Eagle Golf Club in Hudson, Wisconsin to support PTSD research at the Brain Sciences Center. We are deeply appreciative of their fundraising efforts over the years to support veterans research and improve veterans treatment. Our thanks go to them and to all their sponsors.
Dr. Lisa M. James talks about her study of Post Traumatic Stress Disorder in women veterans in a new video featured on the Association of Medical Colleges 2015 Health Equity Research Snapshot website.

"Neural communication in posttraumatic growth" is the most recent publication by BSC researchers Samantha L. Anders, Carly K. Peterson, Lisa M. James, Brian E. Engdahl, Arthur Leuthold and Apostolos P. Georgopoulos. In this magnetoencephalography (MEG) study, they looked at posttraumatic growth (PTG), or positive psychological changes following exposure to traumatic events. The article is featured in the April 17 2015 issue of Experimental Brain Research.
Posttraumatic growth (PTG), or positive psychological changes following exposure to traumatic events, is commonly reported among trauma survivors. In the present study, we examined neural correlates of PTG in 106 veterans with PTSD and 193 veteran controls using task-free magnetoencephalography (MEG), diagnostic interviews and measures of PTG, and traumatic event exposure. Global synchronous neural interactions (SNIs) were significantly modulated downward with increasing PTG scores in controls (p = .005), but not in veterans with PTSD (p = .601). This effect was primarily characterized by negative slopes in local neural networks, was strongest in the medial prefrontal cortex, and was much stronger and more extensive in the control than the PTSD group. The present study complements previous research highlighting the role of neural adaptation in healthy functioning.
The April 2015 issue of Experimental Brain Research features a Brain Sciences Center research article authored by entitled, "DSM-5 personality traits discriminate between posttraumatic stress disorder and control groups."
The relevance of personality traits to the study of psychopathology has long been recognized, particularly in terms of understanding patterns of comorbidity. In fact, a multidimensional personality trait model reflecting five higher-order personality dimensions — negative affect, detachment, antagonism, disinhibition, and psychoticism — is included in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and represented in the Personality Inventory for DSM-5 (PID-5). However, evaluation of these dimensions and underlying personality facets within clinical samples has been limited. In the present study, we utilized the PID-5 to evaluate the personality profile elevation and composition of 150 control veterans and 35 veterans diagnosed with posttraumatic stress disorder (PTSD).
Results indicated that veterans with PTSD endorsed significantly more personality pathology than control veterans, with scores on detachment and psychoticism domains most clearly discriminating between the two groups. When personality domain scores were considered as parts of each subject's personality profile, a slightly different picture emerged. Specifically, the PTSD composition was primarily characterized by detachment and negative affect, followed by disinhibition, psychoticism, and antagonism in that order of relative importance. The profile of the control group was significantly different, mostly accounted for differences in antagonism and psychoticism.
Using these complementary analytic strategies, the findings demonstrate the relevance of personality pathology to PTSD, highlight internalizing features of PTSD, and pave the way for future research aimed at evaluating the role of shared maladaptive personality traits in underlying the comorbidity of PTSD and related disorders.

The International Society of Motor Control has elected BSC Director Apostolos Georgopoulos as the recipient of the 2015 Bernstein Prize. The Bernstein Prize is the highest award of the Society. It is presented at each biennial meeting to an individual who has made an exceptional contribution to the understanding of motor control as reflected in the spirit of Nikolai Alexandrovich Bernstein. The nomination process was supervised by the Vice-President and Awards Chairman of the Society, and the final selection was made by a vote of the Executive Committee and past Bernstein Prize awardees. The prize will be awarded at the next meeting of the ISMC, Progress in Motor Control X, which will be held between July 22-25, 2015, at the Hotel Novotel, Budapest City.
This summer, the Brain Sciences Center will embark on a 3-year research project entitled, "Gulf War Illness as a Brain Autoimmune Disorder". In order to to establish a rationale for diagnosis and treatment for vets with GWI, investigators will study its commonalities with multiple sclerosis, Sjogren's syndrome and posttraumatic stress disorder (PTSD).

BSC investigators Vassilios Christopoulos, Angeliki Georgopoulos and Apostolos P. Georgopoulos have published their paper entitled,"The effect of apolipoprotein E4 on synchronous neural interactions in brain cultures" in the April 2015 issue of Experimental Brain Research.
To their knowledge, this is the first study of the effects of apoE4 on neural network function in vitro. ApoE4 has been associated with various aspects of brain function and disease. The mechanisms of action of apoE4 in the brain are only partially understood and encompass various levels of reference. At the gross disease level, apoE4 is a known risk for Alzheimer’s disease, is involved in early onset of Alzheimer’s disease neuropathology in Down’s syndrome, adversely affects the sequelae of traumatic brain injury, affects susceptibility, clinical type and progression rate in multiple sclerosis, and is associated with higher symptom severity in posttraumatic stress disorder (PTSD).
