Neural Plasticity
|August 1, 2015
Summary
Multiple sclerosis (MS) involves brain damage, but the brain can compensate through neuroplasticity. Understanding the molecular basis of this plasticity may reveal new therapeutic targets for MS.
Area of Science:
- Neuroscience
- Immunology
- Neurology
Background:
- Multiple sclerosis (MS) is an autoimmune neurodegenerative disorder causing motor and cognitive impairments.
- MS pathology includes inflammation, neurodegeneration, and brain atrophy, leading to progressive disability.
- Relapsing-remitting MS (RR-MS) exhibits exacerbations and remissions, suggesting compensatory mechanisms.
Purpose of the Study:
- To explore the role of neuronal plasticity in compensating for brain damage in MS patients.
- To review current understanding of neuroplasticity in MS, including its molecular underpinnings.
- To identify potential therapeutic targets related to neuroplasticity for MS treatment.
Main Methods:
- Functional neuroimaging techniques such as functional magnetic resonance imaging (fMRI).
- Transcranial magnetic stimulation (TMS) and magnetic resonance spectroscopy (MRS) were used to assess brain function.
- Review of existing literature on molecular factors implicated in MS recovery.
Main Results:
- Evidence confirms the presence of neuronal plasticity in MS patients, even with significant brain damage.
- Central nervous system (CNS) compensation is most apparent in RR-MS.
- Factors like IL-1β, BDNF, PDGF, and CB1Rs are implicated in functional recovery.
Conclusions:
- Neuronal plasticity is a crucial mechanism for compensating for neuronal damage in MS.
- Despite evidence of plasticity, the precise molecular mechanisms in MS remain incompletely understood.
- Identifying and targeting molecular factors involved in neuroplasticity holds promise for future MS therapies.

01:01Neuroplasticity
2.5K
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.

01:15Neurogenesis and Regeneration of Nervous Tissue
2.1K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

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.
