Oscillatory magnetic brain activity is related to dissociative symptoms and childhood adversities – A study in women with multiple trauma

The individual contribution of DSM 5 symptom clusters of PTSD, life events, and childhood adversity to frontal oscillatory brain asymmetry in a large sample of active combatants

“…Neuroscientific research has shown that the left hemisphere of the brain goes through a critical period of intense growth from ages 2 to 4 ( Thatcher, Walker, & Giudice, 1987 ), coinciding with intensive phase of language acquisition ( Corballis, 1991 ), which could thereby be more strongly affected by Childhood Adversity. Other studies also show this association between early life stress and left frontal developmental abnormalities ( Ito et al, 1998 , Miskovic et al, 2009 , Schalinski et al, 2017 ; Thatcher, North, & Biver, 2008 ; Van Harmelen et al, 2010 ).…”

“…Many other studies suggest effects of early childhood stress on functional brain activity, including frontal lateralized disorder ( Ito, Teicher, Glod, & Ackerman, 1998 ; Miskovic, Schmidt, Georgiades, Boyle, & MacMillan, 2009 ). Several studies also show an effect of early childhood stress on left frontal development ( Schalinski, Moran, Elbert, Reindl, & Wienbruch, 2017 ; Van Harmelen et al, 2010 ).…”

Virtual reality and neuromodulation in the induction of out-of-body experience (VR-NIOBE): A proof-of-concept new paradigm for psychological and neuroscientific study of an altered state of consciousness.

“…Further, source localization analyses suggested that increased amplitude of alpha oscillations was seen during OBE, especially in bilateral occipital and occipitotemporal regions, the rTPJ, insula, and medial parietal regions, with an overall right hemisphere dominance, while increased amplitude of lower gamma oscillations was seen in left temporal-occipital junction, left premotor cortex, and left frontal and prefrontal regions, showing an overall left hemisphere dominance (Zeev-Wolf et al, 2017). Decreased amplitude of theta (Krüger et al, 2013) and beta (Schalinski et al, 2017) oscillations has also been seen during resting state as correlated with increased state dissociative experiences. Given there is increasing evidence for neural correlates of OBE in the oscillatory domain, induction procedures that are consistent with what is coming to be known about the brain bases of OBE would provide additional evidence of construct validity for the procedures, albeit acknowledging that our understanding of the brain bases of OBE remains preliminary at this time.…”

Komplexní vývojové trauma a užívání návykových látek

“…). Ovšem PTSD se obtížně zjišťuje jako důsledek vývojového traumatu, neboť komplexní vývojové trauma se odehrává v raném dětství nebo i před narozením dítěte, nejčastěji v interpersonálních interakcích s významnými vztahovými osobami(van der Kolk, 2005).Pokud byli děti a adolescenti vystaveni traumatické události, jsou ve vysokém riziku rozvoje PTSD a řady negativních faktorů spojených s chováním, duševními problémy, vzděláváním(Gillies, Maiocchi, Bhandari, Taylor, Gray, & O'brien, 2016) Schalinski et al (2017). zkoumali disociativní symptomy spojené s traumatem v dětství u žen a jejich výsledky potvrzují abnormální změny na mozku v důsledku posttraumatické poruchy.…”
