Extensive motor skill training induces reorganization of movement representations and synaptogenesis within adult motor cortex. Motor skill does not, however, develop uniformly across training sessions. It is characterized by an initial fast phase, followed by a later slow phase of learning. How cortical plasticity emerges during these phases is unknown. Here, we examine motor map topography and synapse number within rat motor cortex during the early and late phases of motor learning.

Differential Modulation of Motor Cortical Plasticity and Excitability in Early and Late Phases of Human Motor Learning

The interference with PAS-induced plasticity suggests that the initial performance improvement relies on increasing the efficacy of existing synaptic connections, however, the long-lasting changes in the IO curve, SICI curve, and SMO suggest that continued practice enhances performance by changing Motor cortical organization.

Structural dynamics and stability of corticocortical and thalamocortical axon terminals during motor learning

The results suggest that the late stabilization of thalamic boutons in M1 contributes to motor skill learning.

Circuit Changes in Motor Cortex During Motor Skill Learning

Motor Training Promotes Both Synaptic and Intrinsic Plasticity of Layer II/III Pyramidal Neurons in the Primary Motor Cortex

Dynamic changes in glutamatergic, GABAergic, and intrinsic plasticity in M1 layer II/III neurons after the motor training are indicated, suggesting dynamic changes in intrinsic properties.

Coordinated Plasticity of Synapses and Astrocytes Underlies Practice-Driven Functional Vicariation in Peri-Infarct Motor Cortex

The results suggest that rehabilitative training efficacy for improving manual skills is mediated by synaptic plasticity in a region of motor cortex that, before lesions, is not essential for manual skills, but becomes so as a result of the training.

Motor training induces experience-specific patterns of plasticity across motor cortex and spinal cord.

The results demonstrate that the acquisition of skilled movement induces a reorganization of neural circuitry within motor cortex that supports the production and refinement ofskilled movement sequences, showing the robust pattern of anatomic and physiological plasticity that occurs within the corticospinal system in response to differential motor experience.

Forelimb training drives transient map reorganization in ipsilateral motor cortex


Examination of strain-related differences in dendritic morphology in layer II / III pyramidal cells of the forelimb area of the sensory motor cortex in both Long-Evans and Fischer 344 rats after reach-training suggests that further research is required to understand the neural mechanisms underlying the differences in motor behaviour observed in these rat strains.

It is concluded that learning a skilled reaching task implies long lasting structural changes in restricted cortical regions of the motor cortex, which probably reflect a plastic reorganization for storing and retrieving motor skills.



Motor Learning-Dependent Synaptogenesis Is Localized to Functionally Reorganized Motor Cortex

This is the first demonstration of the co-occurrence of functional and structural plasticity within the same cortical regions and provides strong evidence that synapse formation may play a role in supporting learning-dependent changes in cortical function.

Functional reorganization of the rat motor cortex following motor skill learning.

Results demonstrate that motor skill learning is associated with a reorganization of movement representations within the rodent motor cortex.

Strengthening of horizontal cortical connections following skill learning

Rats were trained for three or five days in a skilled reaching task with one forelimb, after which slices of motor cortex were examined to determine the effect of training on the strength of horizontal intracortical connections in layer II/III, and this work shows that skill learning is accompanied by changes in thestrength of connections within adult rat primary motor cortex.

Synaptogenesis and FOS Expression in the Motor Cortex of the Adult Rat after Motor Skill Learning

The data suggest that Fos may be involved in the biochemical processes underlying skill acquisition and that motor learning, as opposed to motor activity, leads to increases in synapse number in the motor cortex.

Imaging Brain Plasticity during Motor Skill Learning

Recent findings suggest that the learning of sequential finger movements produces a slowly evolving reorganization within primary motor cortex (M1) over the course of weeks and this change in M1 follows more dynamic, rapid changes in the cerebellum, striatum, and other motor-related cortical areas over the Course of days.

Motor Skills Training Enhances Lesion-Induced Structural Plasticity in the Motor Cortex of Adult Rats

Findings suggest that adaptive neural plasticity may be enhanced using behavioral manipulations as “therapy,” and support a link between behavioral experience and structural plasticity after brain damage.

Selective Synaptic Plasticity within the Cerebellar Cortex Following Complex Motor Skill Learning

The learning-dependent increase in synapse number observed within the cerebellar cortex is accomplished primarily through the addition of parallel fiber synapses, mainly to Purkinje cell synapses.

Plasticity and primary motor cortex.

The intrinsic horizontal neuronal connections in MI are a strong candidate substrate for map reorganization: They interconnect large regions of MI, they show activity-dependent plasticity, and they modify in association with skill learning.

Cortical ensemble activity increasingly predicts behaviour outcomes during learning of a motor task

Ch chronically recording from neuronal ensembles located in the rat motor cortex, throughout the period required for rats to learn a reaction-time task demonstrated a decrease in the variance of the rats' reaction times and an increase in the time the animals were able to wait for a trigger stimulus.
