From Wikipedia, the free encyclopedia
The lingual gyrus of the occipital lobe lies between the calcarine sulcus and the posterior part of the collateral sulcus; behind, it reaches the occipital pole; in front, it is continued on to the tentorial surface of the temporal lobe, and joins the hippocampal gyrus. The lingual gyrus is so-named because it resembles the tongue in shape.
This region is believed to play an important role in dreaming and vision, especially in recognizing words, regardless of size, font, etc.
