However, the bipolar cells and ganglion cells still remain.

A retinal ganglion cell (RGC) is a type of neuron located near the inner surface (the ganglion cell layer) of the retina of the eye.

A breast cyst is a fluid filled sac within the breast.

And it corresponds to a little cyst that is located below.

Function There are about 1.2 to 1.5 million retinal ganglion cells in the human retina.

The ganglion cells give information about ambient light levels, and react sluggishly compared to the rods and cones.

He had to undergo Larynx surgery on March 30 to remove a cyst that had formed on his vocal cords.

His SPECT scan showed a cyst, the size of a golf ball, occupying the space of his left temple lobe.

Well it turns out it's these neuromodulators, just like the neuromodulators in that little tiny ganglion in the crabs.

So as light enters, it goes through the ganglion and bipolar cells, activating the photoreceptors, and this is exactly how we see.

When the cyst was removed, his behavior completely went back to normal, and he became the sweet, loving boy he always wanted to be.

For example, potato cyst nematodes emerge from their protective cysts in response to a chemical excreted by potatoes they feed on the potatoes and damage the crop.

Light enters through the cornea and the lens, hitting the retina, which consists of a series of different cell types the photoreceptors, the bipolar cells and ganglion cells.

Pathways to the CNS The sensory modality that is detected by the afferent fibers is an important factor to consider because it determines the pathway that the dorsal root ganglion neurons will take within the central nervous system.

So I really think that, as we learn more, it's going to turn out that the whole fly brain is just like a large version of this stomatogastric ganglion, and that's one of the reasons why it can do so much with so few neurons.

The photoreceptor cells are shown here at the top, and then the signals that are detected by the photoreceptors are transformed by various computations until finally that layer of cells at the bottom, the ganglion cells, relay the information to the brain, where we see that as perception.

The amazing thing about this is that it's controlled by a really tiny set of neurons, about two dozen neurons that can produce a vast variety of different motor patterns, and the reason it can do this is that this little tiny ganglion in the crab is actually inundated by many, many neuromodulators.
