The phrase "amplitude of action" is not commonly used in written English, but it is grammatically correct.
You can use it in contexts related to physics, engineering, or metaphorically in discussions about the extent or range of actions taken in a particular situation.
Example: "The amplitude of action in this experiment must be carefully measured to ensure accurate results."
Alternatives: "scope of action" or "range of action".
Simulation studies also unraveled that both decreased conductance of I(Na) and increased conductance of I(K(Ca)) utilized to mimic riluzole actions in skeletal muscle cells could combine to decrease the amplitude of action potentials and increase the repolarization of action potentials.
Whole-cell recordings from BLA pyramidal neurons showed a significant reduction in the frequency and amplitude of action potential dependent spontaneous inhibitory postsynaptic currents (IPSCs), a reduced frequency but not amplitude of miniature IPSCs, and impairment in the modulation of IPSCs via GluK1-containing kainate receptors (GluK1Rs).
The amplitude of action potentials is however much reduced.
These types of currents regulate the frequency and amplitude of action potentials.
Indeed, the lower amplitude of action potential recorded in 3xTg-AD EC neurons may be the results of an increase in the voltage undershoot.
A given neuron might have the ability to differentially modulate the timing and/or amplitude of action potentials impinging on multiple post-synaptic cells, greatly increasing the available computational capacity of a network.
We found that RDX significantly reduced the frequency and amplitude of action-potential dependent sIPSCs in the BLaction-potential dependentat playsIPSCsprinary role in seizure generathen (Aroniadou-Anderjaska et al. 2007, 2008; Mohapel et al. 1996; White and Price 1993).
Time of occurrence and amplitudes of action potentials were digitized by a CED 1401 and stored for off-line analysis.
Pooled data from 8 neurons showed that SKF83959 significantly reduced the amplitudes of action potential (from 96.3±2.1 to 81.8±2.7 mV, paired t test, P<0.001) and increased the half-width of the spikes from 1.2±0.1 to 1.7±0.1 ms, paired t test, P<0.01) (Fig. 7C).
On the contrary the amplitudes of action potential-evoked excitatory postsynaptic currents (EPSCs) tended to be larger that those observed upon rescue with WT CpxI.
The following measurements were made: firing threshold, peak amplitude of the action potential from RMP, action potential half-width, amplitude of the after-hyperpolarization (AHP; measured from RMP), and AHP duration (measured as the time to RMP; Fig. 9C).
