Q

What are the two ways that the body can use dormant nerves during neuronal unmasking?

A

1 - Axon sprouting - new nerve endings grow and connect with undamaged areas.

2 - Reformation of blood vessels.

Q

Who provided evidence for the role of stem cells in recovery from brain injury?

What did they do?

What were the findings?

A

Tajiri.

They randomly split rats with traumatic brain injury into two group, one received transplants of stem cells and the other recited a solution infused into the brain that had no stem cells in.

Three months after the injury, the stem cell rats showed clear development of neutron-like cells in the area, the control group did not.

Q

What are the evaluation points for the stem cell evidence research, one good one bad?

A

Bad = Animal studies are hard to generalise.

Good = Because it was an animal study, ethical issues that would be present with humans are not there.
