As we progress from bipolar cells to ganglion cells to later cells in the visual system,...

As we progress from bipolar cells to ganglion cells to later cells in the visual system, are receptor fields ordinarily larger, smaller, or the same size? Explain the concept of a receptive field in the visual system and provide an example of this concept for a ganglion cell within the retina.

1. Describe the main reaction that occurs in the rod cells in the retina, which generates a nerve impulse that allows us to see. Which role does the geometry of 11-cis-retinal play in this process? What reactions convert all-trans-retinal back to 11-cis-retinal so that the process of vision can continue?

The human retina contains cells called rods and cones that absorb

The human retina contains cells called rods and cones that absorb light and change it to electric signals sent to the brain. There are approximately 120,000,000 rods and 6,000,000 cones in a retina. How is the number of rods in a human retina written in scientific notation?

What circuit motif allows retinal ganglion cells to respond to small spots of light, but not larger ones? This same motif is used to detect sound intensity differences between your left and right ear.

The magnocellular pathway receives information from M ganglion cells about peripheral vision and therefore _______ spatial resolution images from the retina. High Low The _________ is responsible for controlling the diameter of the pupil. Pupilloconstrictor zone Pupilloexpander zone Pupillolengthening zone Pupillomaximizing zone A person’s _______ threshold is measured by taking the smallest amount of a stimulus and gradually increasing its strength until a person correctly guesses the stimulus’s presence 50% of the time. Minimum Difference Absolute Tolerance A higher frequency...

The convergence of rods on ganglion cells a. increases visual resolution b. improves color vision c. creates a blind spot on the retina d. increases visual acuity Hubel and Weisel (1963) recorded from individual neurons from visual cortex. They found that neurons in primary visual cortex a. responded selectively to elementary features of visual stimuli b. responded selectively to geons but not to different colors c. did not respond selectively to any visual stimuli. Desimone, et al (1984) presented macaque monkeys with stimuli that...

Describe all types of associations (hydrophobic interactions, ionic interactions, etc.) that lead to stabilization of tertiary structure. Be detailedin your descriptions. Indicate how eachof these associations can be lost due to denaturation. Give an example of a denaturation cause (high temperature, change in pH, salt, or chemical) that results in the loss of eachtype of association.
