Question
Chapter 50.1, Problem 3CC
Summary Introduction
To determine: The stimulatory response perceived, which is initiated by electrical stimulation of neuron.
Concept introduction: Stimulatory responses are those responses that is stimulated in an organism or induced in an organism. The stimuli can be natural or by external sources such as electrical impulses.

Students have asked these similar questions
Can measures of sensory acuity be obtained through filaments and biothesiometer? Explan why or why not
Do you tink changing the frequency of the biothesiometer vibrations would affect your measured results? Why?
Which settings affect the frequency of stimulation, which affect amplitude
WHAT IF? Suppose a series of pressure waves in yourcochlea caused a vibration of the basilar membrane thatmoves gradually from the apex toward the base. Howwould your brain interpret this stimulus?
Slowly adapting receptors differ from rapidly adapting receptors in :-a- stopping to discharge after a relatively longer period of constant stimulationb- detecting the dynamic properties of stimulic- detecting velocity of stimulid- generating receptor potentials as long as stimulus is applied.

- Watch this video (http://openstaxcollege.org/l/l_3-D1) 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. If both eyes see an object moving in the same direction, but at different rates, what would that mean for spatial movement?arrow_forwardWatch this video (http://openstaxcollege.org/l/occipital) to learn more about a transverse section through the brain that depicts the visual pathway from the eye to the occipital cortex. The first half of the pathway is the projection from the RGCs through the optic nerve to the lateral geniculate nucleus in the thalamus on either side. This first fiber in the pathway synapses on a thalamic cell that then projects to the visual cortex in the occipital lobe where seeing, or visual perception, takes place. This video gives an abbreviated overview of the visual system by concentrating on the pathway from the eyes to the occipital lobe. The video makes the statement (at 0:45) that specialized cells in the retina called ganglion cells convert the light rays into electrical signals. What aspect of retinal processing is simplified by that statement? Explain your answer.arrow_forward32.Enumerates five sensory receptors? thanks asaparrow_forward
- 4 The human eye has a biological control system that varies the pupil diameter to maintain constant light intensity to the retina. As the light intensity increases, the optical nerve sends a signal to the brain, which commands internal eye muscles to decrease the pupil's eye diameter. When the light intensity decreases, the pupil diameter increases. Draw a functional block diagram of the light-pupil system indicating the input, output, and intermediate signals; the sensor; the controller; and the actuator. (Non-anonymous question) * (a) (b) (c) FIGURE P1.7 Pupil is shown black; light beam is shown white. a. Light beam diameter is larger than pupil. b. Light beam diameter is smaller than pupil. c.
