- Cones are denser in the periphery of the retina
- Bipolar cells are denser in the periphery of the retina
- Rods are denser in the periphery of the retina

When we talk about the receptive field of a receptor cell or of a retinal ganglion cell, what are we are
referring to?
the area of the lateral geniculate nucleus of the thalamus to which that cell projects its axons
the location in the primary visual cortex where we will find neurons that the cell is connected to
the part of the retina in which that cell is located
the part of the visual field where a stimulus must be in order to make that cell respond
Where does the bunde of ganglion axons that forms the optic nerve exit the eye?

A speech processor selects sounds in the range of human speech, and a transmitter converts these sounds to electrical impulses, which are then sent to the auditory nerve. Which of the following types of hearing loss would not be restored by a cochlear implant? Hearing loss resulting from absence or loss of hair cells in the organ of Corti. Hearing loss resulting from an abnormal auditory nerve. Hearing loss resulting from fracture of the cochlea. Hearing loss resulting from damage to bones of the middle ear.arrow_forward

Where in the visual signal-processing pathway is Larrys problem occurring?arrow_forwardOccupational Hearing Loss Frequent exposure to loud noise of a particular pitch can cause loss of hair cells in the part of the cochlea that responds to that pitch. People who work with or around noisy machinery are at risk for such frequency-specific hearing loss. Taking precautions such as using ear plugs to reduce sound exposure is important. Noise-induced hearing loss can be prevented, but once it occurs it is irreversible because dead or damaged hair cells are not replaced. FIGURE 33.24 shows the threshold decibel levels at which sounds of different frequencies can be detected by an average 25-year-old carpenter, a 50-year-old carpenter, and a 50-year-old who has not been exposed to on-the-job noise. Sound frequencies are given in hertz (cycles per second), The more cycles per second, the higher the pitch. FIGURE 33.24 Effects of age aria occupational noise exposure.
