Neuro TA Session 2/16

Select all the true statements about sensory transduction:

• Receptors convert forms of energy into neural signals that travel to the spinal cord and brain  

• Only somatic sensations are conveyed using sensory transduction  

• Converting chemicals into a neural signal is an example of sensory transduction  

• Converting a brain signal into a muscle action is an example of sensory transduction 

• Converting a mechanical force into a neural signal is an example of sensory transduction 

Which of the following describes the just noticeable difference?  

• Detection of a sensory signal depends on the stimulus intensity and the state of the individual  

• The minimum change in stimulus intensity required to notice a variation, dependent on the environment  

• The minimum change in stimulus intensity to notice a variation, independent of the environment  

• Minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time  

• Adequate stimulus is present for which the sensory receptors are particularly sensitive to  

What are key factors that the sensory system must encode for information to be useful?

What are the general classifications of receptors?
