Abstract:
· Neuroplasticity, the brain’s capacity to adapt to internal and external environmental changes, occurs physiologically throughout growth and in reaction to damage. Many MRI studies of neuroplasticity have shown strong evidence that the brain changes quickly and extensively when people have new experiences.
· In this paper, we review the most advancement in the role of neuroradiology in neuroplasticity and using biomarkers.
o Detecting neuroplasticity in global brain circuits in vivo is critical for understanding various processes such as memory, learning, and injury healing.
o MRI-biomarkers can be used to check for corticospinal integrity and how well motor resources are used. White matter neuroplasticity is studied via MRI. It has been used to study structural changes using diffusion tensor imaging (DTI)
o The ultrafast fMRI (ufMRI) technique allows for high spatiotemporal sensitivity and resolution in dispersed brain circuits to detect fMRI signals more connected with the underlying neural dynamics.
White matter hemodynamics may change over time, explaining functional neuroplasticity in this tissue.
