gyral positive

Morphology

gyral = gyrus (semi-transparent) = gyrus + al

The adjective is formed regularly from the anatomical noun 'gyrus', but the specialized scientific sense may not be readily inferable for many learners.

Etymology

Gyral comes from gyrus, an old word meaning 'circle' or 'ring'. Brains have many curved, ring-like folds called gyri, so gyral means 'relating to those folds'.
