Background: The aim of the present study was to investigate the mediating role of defense mechanisms in the relationship between behavioral brain systems and Alexithymia in students of Sari Farhangian University. Method: The statistical population of this study was all students of Farhangian University of Sari in the academic year of 2018-2019. From this statistical population, a sample of 2...
background: astrocytes are cells within the central nervous system which are activated in a wide spectrum of infections, and autoimmune and neurodegenerative diseases.in pathologic states, they produce inflammatory cytokines, chemokines, and nitric oxide (no), and sometimes they induce apoptosis.their protease-activated receptors (pars) can be activated by proteases, e.g.thrombin and ...
Objective(s):Melatonin is known as an anti-inflammatory agent, and it has been proven to exert neuroprotection through inhibition of cell death (apoptosis) in several models of brain injury.Secondary injury following the primary traumatic brain injury (TBI) results in glial cells activation, especially astrocytes. In fact, astrocyte activation causes the production of pro-inflammatory cytokines...
Autism spectrum disorder (ASD) is a mental condition, present from early childhood, characterized by great difficulty in communicating and forming relationships with others and using language. In the last four decades many studies have shown that immune responses in different regions of brain play an important role in ASD pathogenicity. A conservative estimate based on the research suggests tha...
Abstract: The role of meditation in prevention and healing of mental illness is not negligible. For this purpose, various studies have tried to study the brain mechanisms involved in meditation. But the results have not been consistent enough. In this article we review what we have coherence on these results due to a variety of meditation and differences in the activation of different brain ...
The aim of the present study was to investigate psychological damage aspects, including the Internalizing and externalizing problems based on the dimensions of behavioral activation system (BAS) and behavioral inhibition system (BIS). For this purpose, first, 270 persons of high school adolescent students (including boys and girls) of arak's schools were selected through a multistage cluster sa...
near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...
The development of the brain as the most complex structure of the human body is a long process that begins in the third week of pregnancy and continues until adulthood and even until the end of life (1). Human brain myelination begins one to two months before birth in the visual system and eventually lasts until the age of two in other sensory systems and then the motor systems (4). Processes a...
سیستمهای مغزی بازداری و فعالسازی رفتاری (BIS/BAS) و برتری نیمکرهای در افراد با و بدون آلکسیتیمیا
The present research was a causal-comparative study with ex post facto method to evaluate brain behavioral inhibition and activation systems (BIS/BAS) and hemispheric dominance in alexithymia. For this purpose, 25 university students without alexithymia symptoms and 25 university students with alexithymia were selected with purposive sampling among male and female undergraduate students of Bona...
