Increased neural processing and lifetime adversity during a traumatic event merge to elevate the frequency of intrusive traumatic memories and the suffering they cause, as per a new research in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. The elevated neural processing was discovered in brain areas essential for memory and emotion. The spontaneous recollection of traumatic events is a fundamental symptom of PTSD (posttraumatic stress disorder), and the results can assist study why some individuals are vulnerable to the effects of traumatic experiences and others are not.
“Knowing why some individuals develop intrusive experience of a traumatic or stressful event and others do not is an essential step towards treating and preventing posttraumatic stress disorder,” claimed Editor of Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, Cameron Carter, to the media in an interview.
Owing to the nature of actual trauma, which encompasses many various kinds of adversity and takes place randomly, it is not possible to study how neural processing at the time of natural events adds to PTSD.
On a related note, researchers from the stem cell institute HI-STEM and the DKFZ (German Cancer Research Center) in Heidelberg have been successful for the first time in directly reproducing human blood cells into an earlier unidentified kind of neural stem cell. These persuaded stem cells are akin to those that take place during the premature embryonic growth of the main nervous system. They can be multiplied and modified indefinitely in the culture dish and can symbolize an essential basis for the growth of regenerative treatments.
Stem cells are believed to be our tissues’ all-rounders: they can increase indefinitely and then create all conceivable types of cell. In 2006, Shinya Yamanaka (the Japanese scientist) indentified that such cells can also be created in the lab from developed body cells.
