Question
Chapter 17.1, Problem 1AWYK
Summary Introduction
To determine:
Types of neurons required to read braille.
Types of sensory nerve endings required to read braille.
Introduction:
In the animals, the nervous system that is responsible for sensing the information is the sensory system. This system comprises of neural pathways, sensory neurons, and various parts of the brain to signal the senses. The sensory systems are required for vision, taste, smell, balance, hearing, touch, and temperature. The types of sensory systems are the gustatory system, somatosensory system, auditory system, visual sensory system, and primary olfactory system.

Watch this video (Links to an external site.) to learn more about how the brain perceives 3-D motion. Similar to how retinal disparity offers 3-D moviegoers a way to extract 3-D information from the two-dimensional visual field projected onto the retina, the brain can extract information about movement in space by comparing what the two eyes see. If movement of a visual stimulus is leftward in one eye and rightward in the opposite eye, the brain interprets this as movement toward (or away) from the face along the midline. Which eye is visualizing leftward stimulus?
Drag the labels onto the diagram to identify the components of somatic sensory pathways.

cord
Second synapse in thalamus,
contralateral to the stimulus

Third synapse in primary
somatic sensory cortex,
contralateral to the stimulus

SOMATOSENSORY PATHWAYS
PET (positron emission tomography) scans of the brains of people who have been blind since birth reveal high neural activity in the visual centers of the cerebral cortex when these people read Braille. However, when sighted individuals run their fingers over the raised letters of Braille, the visual centers do not show increased activity. Explain these experimental results.

He is testing visual acuity in patients for the first time and feels nervous about it. However, Cassey remembered when he did it in his clinical procedures class, so he takes a deep breath and calls the patient, Mr. Saleto. After identifying the patient and welcoming him in the room, Cassey explains the procedure to Mr. Saleto. What should be the distance between Mr. Saleto and the Snellen chart? What instructions can Casey give to Mr. Saleto if he uses glasses? By using the Snellen chart, is Cassey testing distance or near visual acuity? What does it mean if the result of the test is 20/60?

- A scientist has dissected out a small section of the retina and is able to directly record the action potential firing rate in a single ganglion cell. Assume there is a on-center off-surround bipolar cell connected to an on-center off-surround ganglion cell. When applying ‘Stimulus 1’ the scientist records a moderate action potential rate. When applying ‘Stimulus 2’ the rate of action potentials increases substantially. In the context of this experiment no illumination is an option as a 'Stimulus'. ‘Stimulus 2’ would result in what response in the bipolar cell (the one connected to the ganglion cell the scientist is measuring)? A. A large depolarization of the bipolar cell membrane B. The bipolar cell membrane would remain at the resting membrane potential C. A large hyperpolarization of the bipolar cell membrane D. A small hyperpolarization of the bipolar cell membrane E.
