How can you tell if bumps on the oscilloscope trace are due to the stimulus artifact or are part of a compound action potential?
The stimulus artifact is biphasic and roughly symmetrical. If you reverse the polarity of the stimulus you will see no or little change in the stimulus artifact but should see a decrease or absence of the neural response. The rate of change in a stimulus artifact is generally an order of magnitude faster than most neural responses so that filtering will disproportionally affect it. Always set your stimulus to lowest strength needed to elicit a response before reversing polarity. If you are on the wrong polarity this has the risk of killing your preparation.
What is the lowest frenquency that humans can hear?
The lowest frequency that the human ear can detect is that of 20Hertz.
What does the medical term threshold mean?
The place or point of beginning; the outset.The lowest point at which a stimulus begins to produce a sensation.The minimal stimulus that produces excitation of any structure, eliciting a motor response.
What is the difference between absolute threshold and difference threshold?
absolute threshold is the lowest level that a person will feel sensation differential threshold is the minimal difference that a person can detect between two similar stimuli For example a change in volume in certain frequencies would be crossing the absolute threshold, how much that change would need to be for someone to detect it would be dealing with the difference threshold.
What is the lowest stimulus voltage that induces active force in the skeletal muscle?
It is called the threshold voltage and is around -70 mvolts.
How do you change fraction in lowest term?
Find the highest common factor of the numerator and the denominator and divide the factor into both of them to change the fraction into its lowest terms.
How do you change 0.006 to a fraction in lowest terms?
It is: 0.006 = 6/1000 = 3/500 in its lowest terms
Where is the highest and lowest elevation change in the shortest distance?
no where
Which region of the nervous system contains the respiratory center?
The respiratory center is located in the medulla oblongata, which is the lowest part of the brain stem.
How do you change 0.565 into a fraction in its lowest term?
0.565 as a fraction is 565/1000 and it is 113/200 in its lowest terms
What is the differences between the absolute threshold and the differential threshold Which is more important to marketers?
The absolute threshold is the minimum intensity of stimulus required to be perceived. In other words, it is the intensity amount which is needed to detect the difference between nothing and something. It is the lowest level at which an individual can experience a sensation.On the other hand, the minimal difference that can be detected between two stimuli is called the difference threshold or the j.n.d. (just noticeable difference)The main difference between the two concepts is that the differential threshold is a relative concept. Whereas the absolute threshold deals with whether or not a stimulus can be perceived, the differential threshold refers to the intensity difference needed between two stimuli before people can perceive that the stimuli are different.The marketing implication of absolute threshold is that consumers will only perceive a marketing stimulus when it is higher than absolute threshold. In other words, if images or words in a commercial are too small, consumer's sensory receptors will not ve activated and the stimulus will not be perceived. The differential threshold also has very important marketing applications Difference Threshold: The difference threshold, also known as the just noticeable difference (jnd), is the minimum difference in stimulation that a person can detect 50 percent of the time. We experience the difference threshold as a just noticeable difference. For example, let's say I asked you to put your hand out and in it I placed a pile of sand. Then, I add tiny amounts of sand to your hand and ask you to tell me when you notice any change in the overall weight. As soon as you can detect any change in the weight, that difference between the weight of the sand before I added that last bit of sand and the amount of sand after I added it, is the difference threshold.The absolute threshold is the minimum intensity of stimulus required to be perceived.
