Summary Introduction
Introduction:
The perception of items that are present in the surroundings is termed as sight or vision. This perception occurs by means of reflection or emission of light from those objects. The retina, the neural component, is one of the principle components of the eyeball. It consists of three cell layers, and these cell layers are composed of ganglion cells, bipolar cells, and photoreceptor cells. The photoreceptor cells are involved in the absorption of light and produce a chemical or an electrical signal. These cells are of three kinds namely cones, rods, and some ganglion cells. These cone and rod cells generate visual images, and these cells are related to ependymal cells located in the brain.

Students have asked these similar questions
A scientist has dissected out a small section of the retina and is able to directly record the action potential firing rate in a single ganglion cell.
Assume there is a on-center off-surround bipolar cell connected to an on-center off-surround ganglion cell.
When applying ‘Stimulus 1’ the scientist records a moderate action potential rate. When applying ‘Stimulus 2’ the rate of action potentials increases substantially.
In the context of this experiment no illumination is an option as a 'Stimulus'.
‘Stimulus 2’ would result in what response in the bipolar cell (the one connected to the ganglion cell the scientist is measuring)?
A. A large depolarization of the bipolar cell membrane
B. The bipolar cell membrane would remain at the resting membrane potential
C. A large hyperpolarization of the bipolar cell membrane
D. A small hyperpolarization of the bipolar cell membrane
E. A small depolarization of the bipolar cell membrane
Receptor cells that are neurons with sensory dendrites are faster than receptor cells that are separate from neurons. Why is that, and why might that be important in, for example, the sense of touch versus vision?
