The original motivation for this study was the observation in previous human experiments that the motor neuron firing frequency (recorded from the motor units in the EMG) was lower at derecruitment than that at recruitment, with slow linearly varying voluntary contractions. Are the lower firing rates at derecruitment correlated with a change in the postspike afterhyperpolarization (AHP) after preceding spike trains? This question was investigated by intracellular recordings from cat motor…

Effects of persistent inward currents, accommodation, and adaptation on motor unit behavior: a simulation study.
TLDR
This work focused on the difference in firing rate of low-threshold motor units when higher threshold motor units were recruited and subsequently derecruited, referred to as ΔF, which has been used to evaluate the extent of PIC activation during voluntary behavior.
Contribution of Intrinsic Motoneuron Properties to Discharge Hysteresis and Its Estimation 1 Based on Paired Motor Unit Recordings. a Simulation Study. 2 3 Short Title: Discharge Hysteresis in Motoneurons 4 5
TLDR
Variations in discharge hysteresis and ΔF values primarily reflect the contribution of dendritic PICs to motoneuron activation, although other factors can contribute.
Contribution of intrinsic motoneuron properties to discharge hysteresis and its estimation based on paired motor unit recordings: a simulation study.
TLDR
Results indicate that, although other factors can contribute, variations in discharge hysteresis and ΔF values primarily reflect the contribution of dendritic PICs to motoneuron activation.
Evidence of two modes of spiking evoked in human firing motoneurones by Ia afferent electrical stimulation
TLDR
Findings provide evidence for a possibility of two modes of spiking in firing motoneurones within the low-frequency, sub-primary range, characteristic for voluntary muscle contractions and postural tasks.
Characteristics and organization of discharge properties in rat hindlimb motoneurons.
The discharge properties of hindlimb motoneurons in ketamine-xylazine anesthetized rats were measured to assess contributions of persistent intrinsic currents to these characteristics and to…
The Subprimary Range of Firing Is Present in Both Cat and Mouse Spinal Motoneurons and Its Relationship to Force Development Is Similar for the Two Species
TLDR
This study systematically addresses the proposed discrepancies between mice and larger species (cats) and demonstrates that mouse motoneurons, in fact, use rate modulation as a mechanism of force modulation in a similar manner to the classical descriptions in larger animals.
Intrinsic excitability of human motoneurons in biceps brachii versus triceps brachii.
TLDR
It is concluded that human elbow flexor and extensor motor units exhibit differences in intrinsic excitability, contributing to different neural motor control strategies between muscle groups.
Intrinsic properties of mouse lumbar motoneurons revealed by intracellular recording in vivo.
TLDR
The data demonstrate that mouse spinal motoneurons share many of the same properties that have been demonstrated previously for cat, rat, and human motoneuron properties in transgenic mouse strains.
Repetitive doublet firing in human motoneurons: evidence for interaction between common synaptic drive and plateau potential in natural motor control.
TLDR
The results suggest a plateau potential role in specifying the essential firing pattern, doubling, of some MUs rather than its effect on firing behavior of MN pool, on the whole, during voluntary muscle contractions in humans.

Relationship of firing intervals of human motor units to the trajectory of post‐spike after‐hyperpolarization and synaptic noise.
TLDR
Interspike interval distributions from human motor units of a variety of muscles were analysed and it was concluded that synaptic noise plays a major role in the excitation of tonically firing human motoneurones and that the noiseless mot oneurone with a linear trajectory provides an inadequate model for the conscious human.
Relationship between the time course of the afterhyperpolarization and discharge variability in cat spinal motoneurones
TLDR
Since the interval death rate is likely to reflect the instantaneous distance to threshold during the interspike interval, it provides a functionally relevant measure of fluctuations in motoneurone excitability during repetitive discharge.

TLDR
The finding that synaptic excitation can produce plateau activation below the recruitment level is of importance for the interpretation of its function.
Bistability of alpha‐motoneurones in the decerebrate cat and in the acute spinal cat after intravenous 5‐hydroxytryptophan.
TLDR
It was found that short‐lasting depolarizing current pulses through the recording microelectrode could trigger a self‐sustained firing in the motoneurone provided that the bias current was kept within certain limits and HyperpolarizingCurrent pulses terminated the firing.

TLDR
It is concluded that the AHP conductance is the decisive factor for determining the f/i relations as well as the interspike voltage trajectories in motoneurones.
Mechanisms underlying the early phase of spike frequency adaptation in mouse spinal motoneurones
TLDR
Measurements of Na+ channel availability including action potential amplitude, action potential threshold and maximum depolarization rate of the action potential were found to correlate with instantaneous firing frequency suggesting that the availability of fast, inactivating Na+ channels is involved in SFA.

Activation patterns of hindlimb motor units in the awake rat and their relation to motoneuron intrinsic properties.
TLDR
The sharp recruitment jumps during locomotion and muscle stretch are proposed to have resulted from the additional depolarization produced by the activation of plateau potentials at recruitment, and the sustained activation of plateaus subsequent to recruitment may have produced the prolonged firing of the motor units during sinusoidal muscle stretch.
