Abstract  Scores of the performance scale of the Wechsler Adult Intelligence Scale (WAIS) declined linearly with age from the 6th decade, whereas those of the verbal scale did not. This decrease in performance intelligence was thought to be related to an age‐related frontal atrophy. The relationship between scores of the WAIS and changes in regional cortical gray matter density were examined in healthy elderly subjects using voxel‐based morphometry. Thirty healthy non‐demented individuals >50… 
oving forward : Age effects on the cerebellum underlie cognitive nd motor declines
There is evidence to indicate that there are morphological age differences in the cerebellum that are linked to motor and cognitive behavior, and Cerebellar morphology is often as good as – or better – at predicting performance than the prefrontal cortex.
Fronto‐cerebellar loop and declines in the performance intelligence scale
It is found that the right neocerebellum was significantly associated with scores of the performance intelligence scale while frontal lobes were not, and the right cerebral hemisphere, which mediates non-verbal performance, is connected to the right cerebellar hemisphere.
Brain Structural Networks Associated with Intelligence and Visuomotor Ability
The results support the parieto-frontal integration theory of intelligence by demonstrating how each core region for intelligence works in concert with other regions and revealed how the cerebellum is associated with intelligence and cognitive functions.
Working memory across the lifespan: A cross-sectional approach
The aim of the present study was to extend previous lifespan research to a wide age range (5 to 80 year olds) and investigate any potential differences in the development and decline of working

Neural correlates of individual differences in personality and intelligence : Studies using an isochronous timing task and voxel based morphometry
It is easy to imagine that humans have always noticed the differences between themselves and others and perhaps even speculated about the origins of these differences. The study of individual


Performance on frontal lobe tests in healthy, older individuals
Comparing performance of healthy middle‐aged and older individuals on four frontal lobe tests to provide information regarding age differences in frontal lobe abilities suggested that in a medically and psychiatrically healthy population of older adults, minimal evidence of age Differences in frontal lobes can be documented.
Volumetric asymmetries of the human brain: Intellectual correlates
Neuroanatomical and cognitive correlates of adult age differences in acquisition of a perceptual‐motor skill
It is concluded that in a healthy population showing no clinical signs of extrapyramidal disease, age‐related declines in procedural learning are associated with reduced volume of the cerebellar hemispheres and lower nonverbal working memory scores.
Intelligence and brain structure in normal individuals.
The results suggest that the size of some cerebral structures may account for a significant, but modest, proportion of the variance in human intelligence.

Is the pattern of intellectual growth and decline across the adult life span different for men and women?
Gender comparisons on the WAIS-R suggest that both men and women maintain their crystallized abilities through old age, but show early, rapid declines in fluid ability.
The neuroanatomy of autism: a voxel-based whole brain analysis of structural scans.
Structural MRI data on 15 high-functioning individuals with autistic disorder provides converging evidence of the physiological basis of social cognition.
Problem solving ability in aging and dementia: Normative data on a non-verbal test
A non-verbal problem solving task, viz. a semplified version of Shallice’s London Towers Test, was given to 131 normal subjects to obtain normative data relating to age, education and sex, and the age-related decline of performance in normals was apparent.
