The phrase "action potential size" is correct and usable in written English.
It can be used in scientific or medical contexts, particularly when discussing the characteristics of nerve impulses or cellular activity.
Example: "The action potential size can vary depending on the type of neuron and its physiological state."
Alternatives: "magnitude of action potential" or "amplitude of action potential".
In contrast, three monkeys injected with control AAV did not show a marked change compound muscle action potential size (Fig. 2A).
In TDP-43-expressing monkeys, the compound muscle action potential size on the contralateral side was not changed in the early stage (3 5 days after the onset of motor symptoms), but showed milder reduction of compound muscle action potential size in the late stage (Fig. 2B).
Since Flag TDP-43 messenger RNA was detected in the spinal cord contralateral to the injected side by real-time polymerase chain reaction analysis, the AAV virus was shown to spread contralaterally through the spinal cord causing motor paresis and reduction of compound muscle action potential size in the opposite forelimb.
We suggest that it is this interplay between on the one hand SR Ca2+ depletion and plasma membrane Ca2+ entry and depolarization, and on the other, store refilling, signal termination and repolarization, that leads to the activation of action potential bursts size and oscillations of intracellular Ca2+ and force.
The analyses rely almost completely on a physiological characterization of synaptotagmin VII knockout mice, and data interpretation is greatly aided by the selective effect with no observable change in the response to a single action potential or pool size.
Putative DA neurons were recorded in the lateral VTA and identified using common criteria such as localization, cell body size, broad action potential, and large Ih current52.
Together with the effect of dendritic tree size on action potential kinetics, we conclude that the larger dendrites of human L2 and L3 pyramidal neurons can explain both the faster action potential onset and encoding of faster membrane potential changes in action potential timing with respect to mouse pyramidal neurons (Eyal et al. 2014; Testa-Silva et al. 2014).
However, when I increased the stimulus current further, the action potential generated started changing shape and size and started looking weird.
We further determined that Type-1 neurons display a lower action potential threshold and a smaller soma size than Type-2 neurons.
Because nerve impulses are not graded in amplitude, it is not the size of the action potential that is important in processing information within the nervous system; rather, it is the number and frequency with which the impulses are fired.
Similarly, the depolarization-activated outward omega current would oppose the inward sodium current during the rising phase of the action potential and contribute to the reduced size and altered shape of action potentials.
