Yes, it can be because threshold and rheobase both are the voltage required to generate an action potential. The difference lies in that the treshold can be a voltage higher than rheobase.

The minimum stimulus needed to cause a contraction is called the?
threshold stimulus
What can increase a strong stimulus?
threshold stimulus
Stimulus at which the muscle first contracts perceptibly?
Threshold stimulus
What stimulus below this intensity will result in no response in a neuron?
Threshold stimulus
What does a threshold stimulus cause?
Jesus
What is the minimal level of stimulus to cause a muscle contraction?
it is known as the threshold stimulus usually seen in tonic contraction
What is meant by coding of stimulus intensity?
Threshold
Minimum level of stimulation required to trigger a neural impulse?
An action potential needs to occur to trigger the neurons but the action potential depends on whether a stimulus is able to bring the membrane potential to a certain level termed the THRESHOLD. This threshold is about -55 mV for most neurons, but the stimulus needs to bring the membrane potential to this certain level or it will not be triggered. Relating to the ALL-OR-NONE PRINCIPLE, which if the threshold is not acquired then an action potential will not occur but once a stimulus is strong enough to depolarize (making the inside of the cell less negative going from -70 mV to -55 mV) it will trigger. The resting potential is -70 mV which the stimulus needs to bring it up to -55mV.
How does the threshold stimulus influence muscle contraction?
The threshold stimulus is the stimulus required to create an action potential. So any stimulus under this level will not cause muscle contraction, while a stimulus above this level will cause the muscle to contract. The higher the stimulus the more muscle fibers are recruited, and thus the higher the response.
What is perceptual threshold?
Perceptual threshold refers to the minimum level of stimulus needed for a person to detect a particular stimulus. It is the point at which the stimulus becomes strong enough to be recognized by an individual's senses.
A muscle fiber will not respond to a stimulus until that stimulus reaches what?
it will not respond until it reaches the threshold level
What is the Point at which a person can detect a stimulus 50 percent of time it is presented?
The point at which a person can detect a stimulus 50% of the time it is presented is known as the absolute threshold. This threshold represents the minimum intensity of a stimulus needed to detect it half of the time. It is often used in psychology to study perception and sensory processing.
