Myelinated

“We found that if we just transplanted motor neurons into the spinal cord and did nothing else, then the surrounding neighborhood in the spinal cord—the white matter surrounding the spinal fluid, which is full of other, healthy myelinated axons—would see these motor neurons as foreign and reject them,” Kerr says. ❋ Donna Jackson Nakazawa (2008)

In order to coax the nerves to grow out into the paralyzed legs, Kerr had to introduce two last chemicals into his nerve-regenerating cocktail: chemicals that told the myelinated axons that these newly birthed nerves were exactly the same as those that wire the body during fetal development. ❋ Donna Jackson Nakazawa (2008)

Placed along the nerves in the limbs of the body, they tell myelinated axons during development whether to go left or right. ❋ Donna Jackson Nakazawa (2008)

In experiments in lab mice, even very low doses of pleiotrophin, or PTN, significantly enhanced the regeneration of myelinated axons, leading Hoke to hope that PTN may lead to novel treatment options for neurological autoimmune disease. ❋ Donna Jackson Nakazawa (2008)

Because different parts of the brain are pruned and myelinated at different times, there are biological windows of opportunity when children are interested in and able to learn different skills. ❋ Michael F. Roizen (2010)

He had myelinated nerves and a spinal cord and there, within the hard bone box of his skull, he had about a pound and a half of putty-colored aspic: Jesus had a human brain. ❋ Kate Braestrup (2010)

The last brain area to be myelinated is the prefrontal cortex, a region thought to play a role in inhibiting unwanted behaviors. ❋ Valerie Strauss (2010)

SPECT scans indentify blood flow abnormalities consistent with microvascular defects consistent with loss of glial cell energetic metabolic support of neurotransmitters, myelinated neuron action potentials and proper neural network cortical to cortical learning and motor, sensory and abstract concept processing functions. fMRI Functional MRI can demonstrate abnormal myelination and neural pathway functioning with changes in neural traffic and dysmyelination patterns that can be verified on T2 Weighted MRI. ❋ Unknown (2008)

The non-specific association areas are 8 layers thick and made up of non-myelinated neurons. ❋ Unknown (2007)

Normal touch is transmitted to the brain through a network of fast-conducting nerves, called myelinated fibres, which carry signals at 60 metres per second. ❋ Unknown (2002)
