TL;DR: Global grey matter volume decreased linearly with age, with a significantly steeper decline in males, and local areas of accelerated loss were observed bilaterally in the insula, superior parietal gyri, central sulci, and cingulate sulci.

TL;DR: Structural MRIs of the brains of humans with extensive navigation experience, licensed London taxi drivers, were analyzed and compared with those of control subjects who did not drive taxis, finding a capacity for local plastic change in the structure of the healthy adult human brain in response to environmental demands.

TL;DR: It is demonstrated that the referential meaning of action words has a correlate in the somatotopic activation of motor and premotor cortex, which rules out a unified "meaning center" in the human brain and supports a dynamic view according to which words are processed by distributed neuronal assemblies with cortical topographies that reflect word semantics.

TL;DR: Global grey matter volume decreased linearly with age, with a significantly steeper decline in males, and local areas of accelerated loss were observed bilaterally in the insula, superior parietal gyri, central sulci, and cingulate sulci.

TL;DR: There was a significant main effect of sex on brain morphology, even after accounting for the larger global volumes of grey and white matter in males.
