Cognitive neuroscience of aging: explanatory models

Revista española de geriatría y gerontología

Abstract

The aim of the cognitive neuroscience of aging is the study of brain activity and the cognitive processes associated with age. In order to understand the dynamics of neurocognitive activity in older people, the present review highlights four explanatory models. The first one (HAROLD) highlights brain bilaterality, mainly in the pre-frontal cortex. The second paradigm (PASA) places special emphasis on neuronal polarisation (anterior-posterior). The third model (CRUNCH) relates the manifest activity of the brain to the level of complexity of the task. The last one (ELSA) emphasises the spatial and temporal distribution of brain activity in the different phases of recovery. Although different in their content, the four explanatory models are perfectly compatible with the findings reported by neuroimaging techniques, suggesting the use of compensation strategies and cognitive reserve for interventions that may help to optimise the performance of older people.
