Neuronal activity in the motor cortex is understood to be correlated with movements, but the impact of action potentials (APs) in single cortical neurons on the generation of movement has not been fully determined. Here we show that trains of APs in single pyramidal cells of rat motor cortex can evoke long sequences of small whisker movements. For layer-5 pyramids, we find that evoked rhythmic movements have a constant phase relative to the AP train, indicating that single layer-5 pyramids can… 
Whisker movements evoked by stimulation of single motor neurons in the facial nucleus of the rat.
TLDR
The data suggest the following coding scheme for whisker movements in the facial nucleus: 1) Evoked movement characteristics depend on the identity of the stimulated neuron (a labeled line code), 2) The facial nucleus neurons are heterogeneous with respect to the movement properties they encode, and 3) Facial nucleus spikes are translated in a one-to-one manner into whisker movement.
Sensory-Evoked and Spontaneous Gamma and Spindle Bursts in Neonatal Rat Motor Cortex
TLDR
It is suggested that both spontaneously occurring and sensory-evoked gamma and spindle bursts in M1 contribute to the maturation of corticospinal and sensorim motor networks required for the refinement of sensorimotor coordination.
Long-Term Plasticity in Mouse Sensorimotor Circuits after Rhythmic Whisker Stimulation
TLDR
It is shown that a brief period of rhythmic whisker stimulation in anesthetized mice resulted in a frequency-specific long-lasting increase in the amplitude of somatosensory-evoked potentials in the contralateral primary somatoensory (barrel) cortex, suggesting that natural, rhythmic patterns of whisker activity can modify the cerebral processing of sensory information.
Cortical control of a whisking central pattern generator.
TLDR
These findings support the hypothesis that vMCx regulates whisking through its actions on a subcortical CPG, and investigate the involvement of a serotonergic component of the whisking CPG in determining whisking kinematics and the mechanisms through which drive is converted into movements by vibrissa motor units.
Vibrissae motor cortex unit activity during whisking.
TLDR
There was significant coherence between the frequency of MUA and vibrissae movements during free-air whisking but not when animals were using their vibrissa to contact an object.
Vibrissa motor cortex activity suppresses contralateral whisking behavior
TLDR
Anatomical, stimulation and lesion data implicate vibrissa motor cortex in whisker motor control, and data collectively point to movement suppression as a prime function of vibrissal touch.
Spiking in primary somatosensory cortex during natural whisking in awake head-restrained rats is cell-type specific
TLDR
In awake, head-fixed rats, the impact of natural whisker movements on action potential frequencies of single neurons located in different layers of somatosensory (barrel) cortex is quantified.
Vibrissa myoclonus (rhythmic retractions) driven by resonance of excitatory networks in motor cortex.
TLDR
The results demonstrate that rhythmic motor cortex output is capable of driving vibrissa movements on a cycle-by-cycle basis.
Anticipatory activity of motor cortex in relation to rhythmic whisking.
TLDR
The hypothesis that the vibrissal representation in motor cortex (vMCx) initiates and modulates whisking by acting on a subcortical whisking central pattern generator (CPG) is tested and recorded local field potentials in vMCx of behaving Sprague-Dawley rats while monitoring whisking behavior through mystacial electromyograms (EMGs).

Vibrissa movement elicited by rhythmic electrical microstimulation to motor cortex in the aroused rat mimics exploratory whisking.
TLDR
Data are interpreted as demonstrating that M1 cortex can, in principle, initiate the full pattern of whisking on a cycle-by-cycle basis in aroused animals, and may bear on the design of algorithms for neuroprosthetic control of motor output.
Intrinsic firing patterns and whisker-evoked synaptic responses of neurons in the rat barrel cortex.
TLDR
The results show that single neurons integrate rapid synaptic responses from a large proportion of the mystacial vibrissae, and suggest that the whisker-evoked responses of barrel neurons are a function of both synaptic inputs and intrinsic membrane properties.
The relationship of vibrissal motor cortex unit activity to whisking in the awake rat.
TLDR
Findings support a role for vibrissal motor cortex in the initiation and modulation of the overall level of mystacial pad muscular output, but not in the generation of bursts of EMG activity responsible for individual whisking sweeps.
Interaction of sensory responses with spontaneous depolarization in layer 2/3 barrel cortex
TLDR
Surprisingly, whisker deflections evoked fewer action potentials during the spontaneous depolarizations despite neurons being closer to threshold, and the ongoing spontaneous activity regulates the amplitude and the time-dependent spread of the sensory response in layer 2/3 barrel cortex.
Whisker Deafferentation and Rodent Whisking Patterns: Behavioral Evidence for a Central Pattern Generator
TLDR
Optoelectronic instrumentation was used to obtain high-resolution records of the movement trajectories of individual whiskers in rats whose heads were fixed to isolate their exploratory whisking from exafferent inputs, providing strong behavioral evidence for a whisking CPG.
Spatio-temporal subthreshold receptive fields in the vibrissa representation of rat primary somatosensory cortex.
TLDR
It is demonstrated that subthreshold receptive fields are on average large, and the spatio-temporal dynamics of these receptive fields vary as a function of position within the receptive field and strength of excitatory input.
Comparable patterns of muscle facilitation evoked by individual corticomotoneuronal (CM) cells and by single intracortical microstimuli in primates: evidence for functional groups of CM cells.
TLDR
Stimulus intensities were too weak and their repetition rate too slow to evoke muscle excitation evident in the raw EMG record, however, stimulus-triggered averages of the rectified EMGs of coactivated muscles revealed consistent patterns of poststimulus facilitation (PStimF).
The mode of activation of pyramidal tract cells by intracortical stimuli.
TLDR
It is concluded that a weak intracortical stimulation is relatively ineffective in a direct excitation of pyramidal tract cells and that the effects of such a stimulation are mainly indirect, especially when repetitive stimuli are used.
Arm trajectory and representation of movement processing in motor cortical activity
TLDR
This high fidelity neural representation of velocity found in motor cortex can be used to visualize the dynamics of motor cortical activity during drawing and suggests that the cost function governing the rate of drawing is bound by neural processing.
