your optic nerve from the environment around you, and then only 10,000 of those bits actually get to the brain's visual processing area and only a few hundred of those are involved in consciousness, and you know, the conscious processing associated with that visual activity.
Visual guided behavior was significantly reduced however, when
the optic nerve from the second (induced) eye was severed (Noggin - induced eye, 95 % ± 4 % to 57 % ± 7 %, p = 0.002; control, 78 % ± 5 % to 52 % ± 5 %, p = 0.001).

from Massachusetts Eye and Ear / Harvard Medical School have identified inflammatory factors that cause
optic neuropathy in the back of the eye following implantation of a keratoprosthesis (KPro)-- similar to what glaucoma patients experience, without the rise of pressure in the eye — and have shown that blocking one of those factors, tumor necrosis factor alpha (TNFa), successfully halts the development of
optic nerve damage in a mouse model.

from cells within an hour after the
optic nerve is injured acutely — but they were surprised to find that it didn't come
from retinal ganglion cells.
Impulses
from the retinas, for instance, have to travel up the
optic nerve to the thalamus, which relays the signals to the visual cortex in the back of the brain.

optic pathway, affecting the
nerves that carry vision - related signals
from the eye to the brain.

from the monkey's
optic nerves passes through a series of brain locations, each of which is less sensitive to face orientation than the last.
Millions of
nerve fibers running
from the ganglion cells dive through the eye's «blind spot» and form the
optic nerve that carries impulses to the brain.
In fact, so much of the progress that we're making in laboratories, including mine, is on developing neuroprotective therapies that can protect the retina
from degeneration, regenerate
optic nerve fibers all the way back to their targets in the brain, and even replace damaged retinal ganglion cells with self - therapies that completely rebuild the
optic nerve.
We are using these new tools to image the structural features of individual cells, such as the cell body and the axons of the cells, which are long fibers that extend
from each neuron, together forming the
optic nerve that transmits visual information to the brain.
These tissues include the trabecular meshwork, which composes the drain of the eye and regulates intraocular pressure, and the
optic nerve, which transmits visual information
from the eye to the brain.
We seek to determine whether a particular type of imaging, known as «polarization - sensitive» imaging, is capable of reporting on the integrity of sub-microscopic structures within
optic nerve fibers at an early stage of damage
from glaucoma, preceding their complete degeneration and loss
from the eye.
We seek in this proposal to determine whether a particular type of imaging is capable of assessing and reporting on the integrity of sub-microscopic structures within
optic nerve fibers at an early stage of damage preceding their complete degeneration and loss
from the eye.

optic nerves were taken
from transgenic and wild - type mice of 3 to 12 months of age and processed for immunohistochemistry, qPCR, or western immunoblotting.
The pattern of RGC loss in patients as well as information obtained
from laboratory research all point to the fact that an important site of pathology occurs at the
optic nerve head, a region where the axonal cell processes of RGCs exit the eye on their way to the visual centers of the brain.
Generous support
from the Glaucoma Research Foundation allowed us to develop a strategy to comprehensively assess an entire class of biomolecules called lipids for differences that occur during
optic nerve regeneration.
