Summary
Motor skill learning involves dynamic brain activity changes. The motor network shows distinct activation patterns during learning and automatization, crucial for rehabilitation after brain injury.
Area of Science:
- Neuroscience
- Motor Control
- Cognitive Science
Background:
- Motor learning deficits can impede rehabilitation after brain injury.
- Understanding the neural basis of motor learning is vital for therapeutic interventions.
Purpose of the Study:
- To investigate changes in motor network activation during sequential finger motor learning.
- To characterize the cortico-subcortical network's role in motor skill acquisition.
Main Methods:
- Functional magnetic resonance imaging (fMRI) was used to monitor brain activity.
- Twenty healthy volunteers performed a sequential finger motor task over eight blocks.
Main Results:
- Performance improved from block 1 to 4, then plateaued.
- Sensorimotor cortex, premotor cortex, supplementary motor area, and parietal cortex activity increased during early learning and decreased during automatization.
- Cerebellar activity increased linearly, while thalamus and basal ganglia showed unique activation patterns.
Conclusions:
- The study delineated characteristic plastic changes in the cortico-subcortical network during early motor learning.
- Different brain regions play distinct roles in motor skill acquisition and automatization.

01:18Hierarchy of Motor Control
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
01:11Direct Motor Pathways
The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and the...

01:01Neuroplasticity
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
01:14Motor and Sensory Areas of the Cortex
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.

01:25Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.
