The lower swelling, the calcar avis, is produced by the calcarine sulcus, located on the medial surface of the occipital lobe. |
The area of cortex characterized by the stripe of Gennari occupies in man, as mentioned, the calcarine and cuneate region. |
The calcarine fissure passed completely across the gyrus frontitatus on both sides in two cases, on one side in four cases. |
The lesion is one of the left occipital cortex in the cuneate lobe and the neighbourhood of the calcarine fissure. |
Such a loss agrees with a lesion involving the upper part of the cuneate lobe above the calcarine fissure. |
