Prefrontal cortex function has traditionally been associated with explicit executive function. Recently, however, evidence has been presented that lateral prefrontal cortex is also involved in high-level cognitive processes such as task set selection or inhibition in the absence of awareness. Here, we discuss evidence that not only lateral prefrontal cortex, but also rostral prefrontal cortex i...

introduction: prenatal stress has deleterious effects on the development of the brain and is associated with behavioral and psychosocial problems in childhood and adulthood. this study aimed to determine the protective effect of l-arginine on fetal brain under maternal stress. methods: twenty pregnant wistar rats (weighting 200-230 g) were randomly divided into 4 groups (n=5 for each group). th...

There has been no agreement as to whether the prefrontal cortex is especially enlarged in the human brain. To answer this question, we analyzed the only two datasets that provide information on total prefrontal cortex volume based on cytoarchitectonic criteria. One delineated the prefrontal cortex proper on the basis of cytoarchitectonic criteria; the other used a proxy of the prefrontal cortex...

objective(s): drug addiction is one of the fastest growing social problems that researchers, for many years, have been trying to find proper strategies for its prevention and treatment. short-term physical activity is considered as acceptable for the treatment and prevention of addiction. on the other hand, prefrontal cortex is known to be responsible for many of the complex behavioral response...
