What does abverbs of frequency means?

Adverbs of frequency indicate how often an action is performed, such as "always," "often," "sometimes," "rarely," or "never." They provide information about the frequency of an action in relation to time.


Would increasing frequency of stimulation to trigger zone change number of action potentials?

Yes, increasing the frequency of stimulation can increase the number of action potentials generated in the neuron. This is known as frequency-dependent facilitation, where rapid succession of stimuli can enhance the excitability of the neuron and lead to more action potentials being fired.


What is the firing frequency equation?

The firing frequency of a neuron can be estimated by dividing the total number of action potentials generated by the neuron within a given time period by that time period. This can be mathematically expressed as: Firing Frequency (Hz) = Number of Action Potentials / Time Period.


Why does the number of action potentials vary with increased stimulation frequency?

Increased stimulation frequency can lead to a phenomenon called summation, where individual action potentials merge together or "sum" to produce a larger response. This allows for greater depolarization of the membrane potential, leading to more frequent firing of action potentials. As the stimulation frequency increases, the membrane may not return to its resting potential before receiving the next stimulus, resulting in a higher number of action potentials being generated.


What is the relationship between inter-spike interval and the frequency of action potentials?

The inter-spike interval is the time between consecutive action potentials. The frequency of action potentials is inversely related to the inter-spike interval, meaning shorter inter-spike intervals result in higher action potential frequencies. This relationship is crucial in determining the rate of neuronal firing.
