The uncinate fasciculus is a white matter tract that connects the uncus (Brodmann area 35), the anterior temporal areas (temporal pole; Brodmann area 38), the amygdala and the hippocampal gyrus (Brodmann areas 36 and 30) with areas of the frontal lobe (polar and orbital cortex); runs - forming a curve (hook-shaped morphology) around the common trunk of the lateral sulcus (Sylvian fissure) - ventrally to the inferior front-occipital fasciculus.

The uncinate fasciculus is thought to be part of the circuitry involved in the retrieval of word form for proper names ⁶. In fact, the resection of the uncinate fasciculus, in its frontal or temporal part, has long-lasting consequences for face naming.
