Summary
Metaplasticity, the brain
Area of Science:
- Neuroscience
- Cognitive Science
Background:
- Metaplasticity modifies neural plasticity based on prior activity.
- Animal studies show metaplasticity's role in network function and behavior.
Purpose of the Study:
- Review evidence for metaplasticity in the human cortex using non-invasive brain stimulation.
- Investigate the homeostatic and non-homeostatic nature of human metaplasticity.
- Explore the link between aberrant metaplasticity and neurological/psychiatric diseases.
Main Methods:
- System-level investigation of human cortical metaplasticity.
- Utilizing non-invasive brain stimulation techniques.
- Reviewing existing animal and human studies.
Main Results:
- Metaplasticity is operative in the human brain, primarily exhibiting homeostatic properties.
- Non-homeostatic metaplasticity can enhance cortical excitability and learning.
- Aberrant metaplasticity is implicated in neurological and psychiatric disorders.
Conclusions:
- Human cortical metaplasticity is largely homeostatic, regulating network activity.
- Non-homeostatic metaplasticity offers potential for enhancing cognitive functions.
- Targeting metaplasticity shows promise for treating brain diseases.

2.6K
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.

36.9K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...
