- Which statement about the events of photoreception is false? a) as a rod cell hyperpolarizes, its release of neurotransmitter increases b) there is more Na+ entry into a rod cell in the dark than in the light c) bipolar cells release more neurotransmitter in the light than in the dark d) as a bipolar cell depolarizes, its release of neurotransmitter increases e) when a rod cell releases neurotransmitter the bipolar cell it synapses with hyperpolarizesExplain the main cause of nearsighted (myopic) Condition ?Trying to understand this part of the article “As white matter integrity did not return to baseline levels for any inter-injury interval (and did not trend towards returning to baseline levels in the case of the optic tract), it is possible that the window of vulnerability associated with our model may never close.” Based on the quote, what did not return when white matter integrity did not return?

- You want to record membrane potential changes in axons of neurons that process different types somatosensory information. Which sequence ranks the speed of maximum firing rate from slowest to fastest that you predict you will record a) muscle spindle < cutaneous mechanoreceptor < pain and temperature b) pain and temperature < muscle spindle < cutaneous mechanoreceptor c) cutaneous mechanoreceptor < pain and temperature < muscle spindle d) cutaneous mechanoreceptor < muscle spindle < pain and temperature e) muscle spindle < pain and temperature < cutaneous mechanoreceptor f) pain and temperature < cutaneous mechanoreceptor < muscle spindleUnilateral Cerebral strokes can cause deficits in motor control, somatic sensation and vision. However, they do not cause deficits in hearing. The explanation for this is: Auditory information does not reach the cortex Auditory information only goes to one hemisphere. Auditory information goes to both hemispheres How are the outer segments of photoreceptors positioned? between bipolar cells and horizontal cells in the outermost layer of the retina in the ganglion cell layer farthest from the pigment epitheliumOzana was born with cataracts, which made her completely blind. When she was 14 years-old she underwent surgery to remove the cataracts, which allowed visual input to be transmitted to her brain for the first time. However, even though the surgery was a success, Ozana’s vision was never fully functional. A) Describe how the features of neural plasticity might help to explain why Ozana’s vision was not restored. B) Propose one factor that might have increased the chance that Ozana would develop the ability to see, and briefly explain why.
- If someone where has damaged their spinal cord only on the left side, which of the follwoing would be true? A) They would not be able to feel or have a sense of proprioception on thier left side below the lesion. B) They would not be able to feel or have a sense of proprioception on thier right side above the lesion. C) They can't move the right side of their body below the lesion. D) They won't feel pain on the left side below the lesion.what is an example of a sensory neuron being changed by external physical stimulation?Define the term Primary Sensory Coding?
- How does the sensory transduction mechanism in the vestibular and auditory systems demonstrate the importance of the general principle of physiology that controlled exchange of materials occurs between compartments and across cellular membranes?When light strikes a photoreceptor, it reduces the amount of glutamate that it releases. This releases ___ cells from inhibition, allowing them to release more neurotransmitters and excite ___ cells. This produces action potentials that travel down the optic nerve. A) horizontal; amacrine B) amacrine; horizontal C) ganglion; bipolar D) bipolar; ganglionGrandpa can't ever seem to hear what his little granddaughters say. He also can't hear that high-pitched whine in the Subaru engine that everyone else seems to hear. You suspect that grandpa has too much ear wax built up in his external auditory canal, and therefore has developed conduction deafness has damage to the vestibulocochlear nerve has damaged either the utricle or the saccule, though it will be hard to tell which one without further testing has damaged the hair cells closest to the oval window has "selective" hearing loss, because the granddaughters are always trying to get him to play with them when he's tired, and he doesn't want to work on that darned car anymore either.
