The concept of "right-brained" or "left-brained" individuals is considered a widespread myth which oversimplifies the true nature of the brain's cerebral hemispheres (for a recent counter position, though, see below). Proof leading to the "mythbuster" of the left-/right-brained concept is increasing as more and more studies are brought to light.
The other two psychosocial theories are the disengagement theory, with which the activity comes to odds, and the continuity theory which modifies and elaborates upon the activity theory. [5] Though in recent years the acceptance activity theory has diminished, it is still used as a standard to compare observed activity and life satisfaction ...
Human brain in the sagittal plane Ventricles of the brain. Aging entails many physical, biological, chemical, and psychological changes and the brain is no exception to this phenomenon. These various changes have attempted to be mapped by conceptual models like the Scaffolding Theory of
As a researcher of the aging brain, Dr. Richard Isaacson said, the new paper spoke to him. “It was a really practical, narrative overview of the ‘nuts and bolts’ about why this type of ...
The left and right hemispheres are associated with different functions and specialize in interpreting the same data in different ways, referred to as lateralization of the brain. The left hemisphere is associated with language and calculations, while the right hemisphere is more closely associated with visual-spatial recognition and facial ...

Age dynamics of the body mass (1, 2) and mass normalized to height (3, 4) of men (1, 3) and women (2, 4) [24] Comparison of a normal aged brain (left) and a brain affected by Alzheimer's disease. A number of characteristic ageing symptoms are experienced by a majority, or by a significant proportion of humans during their lifetimes.
Treatments with anticancer chemotherapeutic agents often are toxic to the cells of the brain, leading to memory loss and cognitive dysfunction that can persist long after the period of exposure. This condition, termed chemo brain, appears to be due to DNA damages that cause epigenetic changes in the brain that accelerate the brain aging process ...
