1. ON/OFF ganglion cells project to the contralateral LGN True False 2. Indicate which cells produce action potentials Bipolar cell Ganglion cell Photoreceptor 3. Some ganglion cells which respond to color have center-surround receptive fields. This supports the _____ view of color perception Opponent processes Mixing 4. Imagine that your visual field is filled by a gray background, with a pinpoint position in the upper right quadrant we will the “target spot”, which falls in your eyes fovea. Now suppose we shine a red pinpoint light at the target spot for an instant which is of the same level of brightness is the gray background. A neuron in layer 1 and a neuron locates indentically in layer 2 will fire action potentials in response to this stimulus. False True 5. The number of wavelength specific rods in the retina is 3 4 2 1 6. When light strikes a photoreceptor, it will Produce an action potential, releasing glutamate on another cell Release a continuously changing amount of glutamate on another cell, depending on its membrane potential 1.

Explanation / Answer

1. Ganglion cells are the neurons in the retina, which respond to visual stimuli. This is the first step in visual perception. On/off-center ganglion cells give complementary responses. The neural signals originating in the on/off ganglion cells segregated in the retina and lateral geniculate nucleus (LGN). The lateral geniculate nucleus receives information directly from the ascending retinal ganglion cells.

Hence, On/off ganglion cells project to the contralateral LGN. Answer is true.

2. The bipolar cells produce graded potentials. Ganglion cells are neurons in retina that produce action potential to respond to visual stimuli. The firing of action potential depends on whether the neurons are excited or inhibited. Photoreceptor is responsible for convert light into signals.

Here, the answer is (option b) Ganglion cells produce action potentials.
