31. Rarely, they may occur during occipital focal seizures or in parietal lobe seizures. 32. These may be classified by their localisation to occipital , frontoethmoidal, or nasal. 33. In cases where this developmental process is interrupted, occipital horns are disproportionately enlarged. 34. The head exhibits frontal-occipital cranial deformation. 35. Simultanagnosia results from bilateral lesions to the junction between the parietal and occipital lobes. 36. These were the posterior cingulate, medial prefrontal cortex, and the occipital cortex. 37. Less common is pain referred to the temporal, occipital , or retrobulbar region. 38. Occipital alpha waves during periods of eyes closed are the strongest EEG brain signals.39. The muscles receives blood from the occipital artery. 40. Approximate boundaries are the cingulate sulcus dorsally and the parieto-occipital sulcus caudally.
