The transduction process of converting light into neural signals sent to the central nervous system involves which of these steps?
A.
Bipolar Cells collect signals from Rods and Cones.
B.
The Optic Nerve carries signals about light from the Lateral Geniculate Nuclues to the Retinal Ganglion Cells.

- If a person is born blind, in what way do the senses of hearing and touch improve? a. The person gradually develops more receptors in the ears and skin. b. The number of receptors does not change, but each of them becomes more responsive to weak stimuli. c. The receptors in the ears and skin send faster action potentials to the brain. d. Through practice the person learns to increase attention to hearing and touch, and those sensations come to activate the occipital cortex.arrow_forwardWhat function do the malleus, incus, and stapes bones in the inner ear play in processing sounds? A. The bones transform pressure waves into nerve impulses that the brain recognizes as sound. B. The bones equalize pressure between the middle ear and the atmosphere. C. The bones transmit vibrations to the oval window setting the fluid in the cochlea in motion. D. The bones depolarize or hyperpolarize hair cells depending on the direction they vibrate.arrow_forwardWhat happens when to our eyes when we go outside of the house and it is very sunny?
