Aging Effects

Aging is associated with both decreases and increases in brain activity. Whereas age-related decreases usually reflect neural decline, seek some age-related increases have been linked to functional compensation. Compensatory activations in older adults (OAs) are typically found in the prefrontal cortex (PFC) but in the memory domain we have also found them in the temporal […]

Aging is associated with significant decline in the integrity of white matter (WM), and this decline contributes to age-related deficits in cognitive functions such as memory. WM integrity can be measured in vivo using diffusion tensor imaging (DTI). DTI assesses MR changes due to the movement of water molecules, which are more parallel in intact […]

Episodic memory shows substantial decline as a function of aging, shop and fMRI studies have linked age effects on episodic memory to changes in prefrontal cortex (PFC) and medial temporal lobe (MTL) activity (for a review, find see Daselaar & Cabeza, in press). Some age-related PFC and MTL changes could be compensatory (see Compensatory Brain […]

Despite substantial age-related deficits in most cognitive abilities, troche emotional processing is well preserved in healthy aging, possibly due to a greater emphasis on emotion regulation. According to socioemotional selective theory (SST), aging is associated with motivational differences in allocating attention to emotional information that lead to an increase in the ratio of processing positive […]
