Myelination Process and Tween Impulses. Medically reviewed by Joel Forman, MD Building Self-Esteem in Tweens. Medically reviewed by Joel Forman, MD Why Girls Use Social Exclusion.
Medically reviewed by Joel Forman, MD Developmental Needs of Middle School Students. Consistent with the myelination model, in childhood (ages 6-12), girls develop impulse inhibition and control of hyperactive behavior at a strikingly faster rate than boys, resulting in much lower rates of ADHD and conduct disorder in adolescence (Cjte et al., 2002).

tween the turns of the mesaxon leads to the fusion of the opposing plasma membranes with the formation of the major dense line of the myelin lamellae; the intraperiod line is formed by the narrowing of the mesaxon (Fig. 2). In this way, successive layers of compact myelin lamellae are manufactured, and a single myelinated internode is created. Myelin, the insulating layers of membrane wrapped around axons by oligodendrocytes, is essential for normal impulse conduction.
It forms during late stages of fetal development but continues into early adult life. Myelination correlates with cognitive development and can be regulated by impulse activity through unknown molecular mechanisms. Myelination begins at six months of gestation and continues into adulthood.
Hence, in this stage, the glial cells produce myelin. Myelin is a fatty covering that helps neural connections occur more efficiently. The Functions of the Cerebral Cortex.
Pruning, Myelination, and the Remodeling Adolescent Brain The brain rewires during adolescence to increase integration and efficiency. Posted Feb 04, 2014. The velocity of nerve conduction is moderately enhanced by larger axonal diameters and potently sped up by myelination of axons.
Myelination thus allows rapid impulse propagation with reduced. Other changes in the brain during adolescence include a rapid increase in the connections between the brain cells and making the brain pathways more effective. Nerve cells develop myelin, an insulating layer that helps cells communicate.
All these changes are essential for the development of coordinated thought, action, and behavior. An axon that is myelinated can conduct electrical impulses up to 100 times faster than an unmyelinated one. Moreover, myelination allows the axon to recover more quickly after firing—a feature that, combined with the quicker firing, represents a 3,000-fold increase in the nerve fiber’s bandwidth.
