Brain size, sex, and the aging brain.
This study was conducted to examine the statistical influence of brain size on cortical, subcortical, and cerebellar compartmental volumes. This brain size influence was especially studied to delineate interactions with Sex and Age. Here, we studied 856 healthy subjects of which 533 are classified as young and 323 as old. Using an automated segmentation procedure cortical (gray and white matter...
متن کاملSocial life, evolution of intelligence, behaviour and human brain size
Social life is one of the most critical factors of the evolution of the behavior of non-human primates and humans. Several factors, such as an increase in brain size, adaptive modules, and grooming, are related to the complexities of social groups. Although some scientists have mentioned foraging as a rival hypothesis for the evolution of behavior, in this research, we tried to investigate the ...
متن کاملThe Role of Proinflammatory Cytokines in Mediation of Brain Antiedema Effect of Female Sex Steroids Following Traumatic Brain Injury
Background & Aims: Release of proinflammatory cytokines after traumatic brain injury (TBI) is a major cause of brain edema. Previous studies demonstrated that sex steroids decrease brain edema induced by TBI. In this study changes of brain cytokines after the administration of estrogen and progesterone 24 hours after TBI were evaluated. Materials and Methods: Female rats were divided into 7 gro...
متن کاملGlobal aging and the brain.
Intrinsic aging of the brain and its relationship to age-related neurodegenerative diseases need to be understood as part of global aging, which results from gradual accumulation of a variety of kinds of cellular and molecular damage. While certain kinds of molecular lesions are particularly associated with specific diseases, there is substantial overlap between the pathways causing disease and...
متن کاملFlavonoids and the aging brain.
Like in all other organs, the functional capacity of the human brain deteriorates over time. Pathological events such as oxidative stress, due to the elevated release of free radicals and reactive oxygen or nitrogen species, the subsequently enhanced oxidative modification of lipids, protein, and nucleic acids, and the modulation of apoptotic signaling pathways contribute to loss of brain funct...
