Optic nerve

The optic nerve, also known as cranial nerve II, is a paired nerve that transmits visual information from the retina to the brain. The optic nerve is derived from optic stalks during the seventh week of development and is composed of retinal ganglion cell axons and glial cells. In humans, the optic nerve extends from the optic disc to the optic chiasm and continues as the optic tract to the lateral geniculate nucleus, pretectal nuclei, and superior colliculus.

Structure

The optic nerve is the second of twelve paired cranial nerves and is technically part of the central nervous system, rather than the peripheral nervous system because it is derived from an out-pouching of the diencephalon (optic stalks) during embryonic development. As a consequence, the fibers of the optic nerve are covered with myelin produced by oligodendrocytes, rather than Schwann cells of the peripheral nervous system, and are encased within the meninges. Peripheral neuropathies like Guillain-Barré syndrome do not affect the optic nerve. However, most typically the optic nerve is grouped with the other eleven cranial nerves and considered to be part of the peripheral nervous system.

Optic Nerve (CD-ROM)

Optic Nerve is an interactive CD-ROM showcasing the life and work of multimedia artist David Wojnarowicz. The disc includes film, interviews, music, performance, painting and writing from the artist. The release is the first entry in the Red Hot AIDS Benefit Series with a non-musical focus. Production was handled by the Red Hot Organization (RHO) and Funny Garbage, in conjunction with the New Museum of Contemporary Art exhibit entitled "Fever: The Art of David Wojnarowicz."

The disc also features an interactive version of ITSOFOMO — the series of public performances, featuring readings from Wojnarowicz's work, along with multiple video images which the artist either created or selected.

Optic Nerve was originally available from New York City's New Museum bookstore. At that time, four dollars received from the sale of each disc was donated to the Hetrick Martin Institute — an entity which had Wojnarowicz as a patron. The HMI is a leading professional provider of social support and programming for all at-risk youth, particularly lesbian, gay, bisexual, transgender or questioning youth in the New York metropolitan area. The CD-ROM has since become available from the Red Hot Organization.
