The theory is that Tetris thickens the cerebral cortex - part of the brain that plays a key role in memory, attention, perceptual awareness, thought, language and consciousness. "What we found was a change in the brain after playing Tetris," says Dr Richard Haier, a neurologist who led the project....

Oscar Marin details in this journal article his research on the cellular and molecular mechanisms controlling different phases in the migration of the two main classes of neurons in the cerebral cortex, glutamatergic projection neurons and gamma-aminobutyric containing (GABAergic) interneurons,...

This review article details the latest discoveries in the study of the cerebral cortex and its development.  Alessandra Pierani and Marion Wassef discuss how, in order to form functional neuronal networks, distinct classes of cells have to be generated in a precise number.  They...
