Flashcards in Visual Pathways Deck (16):
Less powerful but movable.
More powerful but fixed.
In this type of eye defects we use concave lens to diverge the light.
In this type of eye defects we use convex lens to converge light.
Far sightedness due to aging.
Active in low light levels and has a single range of wavelength.
Active in high light levels and has different ranges of wavelength.
Highest density of cones, which gives very fine detailed picture.
What are the factors that affect the spatial acuity?
Receptor density + convergence ratio
Depolarized by light in their RF center.
ON bipolar cells
Have spiking responses in the center.
ON center ganglion cells
Controls eye and head orienting responses.
Which type of ganglion cells is color sensitive and sensitive to fine stimulus?
P- type cells
Shape and color
