Cortical thickness

Cortical thickness refers to the measurement of the outer layer of the brain, known as the cerebral cortex. This layer is responsible for many complex functions like thinking, memory, and decision-making. Thickness is measured as the distance between the outer surface and the boundary where the cortex ends. Variations in cortical thickness can reflect brain development, aging, or changes due to neurological conditions. Generally, healthy brains have a certain range of cortical thickness, and deviations may indicate differences in cognitive abilities or brain health. It is typically assessed through neuroimaging techniques like MRI scans.
