INTRODUCTION Although it has been speculated for many years that the prefrontal cortex plays a role in long-term memory for events, or episodic memory, only recently have researchers made a concerted attempt to define this role. Most theories of prefrontal function suggest that this region implements " top-down " or " executive " processes that influence a variety of domains, including memory. ...

The progression of manganism with chronic exposure to airborne manganese (Mn) is not well understood. Here, we further investigate the findings on exposure and neurobehavioral outcomes of workers from a silico- and ferromanganese production plant and non-exposed workers from the same community in 1990 and 2004, using a variety of exposure metrics that distinguish particle size and origin within...

A. R. Luria's approach to neuropsychological assessment was examined. Three basic points of departure from Luria are presented: his interpretation of cognitive activity as functional systems, his emphasis on the individualized approach, and the importance of the analysis of the errors. A distinction was introduced between Luria's neuropsychological testing, and Luria's neuropsychological approa...

The numerous successes of contemporary neuroscience and neuropsychology are obvious and undeniable. Brain research is clearly on the rise these days, and brain-related studies are rapidly growing in numbers and expanding in newer cross-disciplinary fields such as brain, mind, and. . . education, computation, consciousness, memory, cognition, behavior, culture, the arts, creativity, and the like...

Luria-Delbrück fluctuation analysis provides a method to estimate mutation rates in cell populations. Originally designed for bacterial populations, the method now is widely applied in somatic cell genetics and in cancer biology. However, there are fundamental genetic differences between bacteria and somatic cells, and this together with the inherent mathematical complexity of fluctuation analy...
