An occipital bun, also called occipital spurs, occipital knob, chignon hooks, PBS head or inion hooks, is a prominent bulge or projection of the occipital bone at the back of the skull. It is important in scientific descriptions of classic Neanderthal crania. While common among many of humankind's ancestors, primarily robust relatives rather than gracile, the protrusion is still relatively prevalent in modern Homo sapiens.^{[citation needed]}

A substantiated theory attributes them to enlargement of the cerebellum, Visual Cortex and secondary visual cortex, not to be confused with imagination using frontal lobes and senses, passively or actively, sensical or non-sensical.

There are still some human populations which often exhibit occipital buns. A greater proportion of early modern Europeans had them, but extremely prominent occipital buns in modern populations are now fairly infrequent, but exist frequently in certain populations.

A study conducted by Lieberman, Pearson and Mowbray provides evidence that individuals with narrow heads (dolichocephalic) or narrow cranial bases and relatively large brains are more likely to have occipital buns as a means of resolving a spatial packing problem.^[1]

The owner of the skull shown from CT data is currently being researched on in Norway; for why head injuries cause negative emotions and dissatisfaction, currently intended to participate in FRISKgruppen.no team of career counsellors to revolve 30 years of medical neglect by social science research and development. For why head injuries cause developmental issues, work and mental capacity reduction that doesn't respond to appeals to emotion or personal content and ambition. Alas, the patient also has a 8 cm crack more visible in greytones over Wernicke's Area and the closest large fissure. Assuming that the left parietal and occipital lobe did not function correctly, and the right hemisphere may have experienced neuroplasticity and adaption, where neurogenesis and regeneration, where normal healing without neurodegeneration is factually called adult neurogeneration. Indicating a neurobiological and psychological adoptions between para-hallucinations, hallucinations from medication. Not to be confused with pseudo-hallucinations of well adjusted individuals irrational analysis of emotion and sensation and what it feels like, and is perceived by them. While both brain organic and connective tissue likely adapt to more available tissue for better efficiency and global cognition in a reversal process. Not likely to see a breakthrough in care services, that is rooted in a notion that there is always a psychological or psychiatric label that offer the correct treatment anyway.
