Gray / white matter

Question 1

What is the typical color for cell bodies & dendrites, and axons?

Answer 1

Gray = cell bodies and dendrites
White = axons because of the myelin
Note: the third substance in the brain is cerebral spinal fluid

Question 2

True or False. Cell bodies & dendrites will always show up as gray or the darker color on the image, and axons will show up as white.

Answer 2

FALSE. The staining technique can be different for each study, therefore, we have to identify cell bodies & dendrites and axons by anatomically

Question 3

Location of cell bodies & dendrites and axons in:
1. Cerebrum
2. Spinal cord

Answer 3

1. Grey matter (cell bodies & dendrites) are on the outside
2. Grey matter is in the center

Question 4

Diffusion tensor imaging

Answer 4

technology where calculations are made based on data of a healthy brain to see what the white matter axons (fibers) look like

Question 5

Color coding in DTI

Answer 5

green: front of brain (eyes) to the back of the brain
warm colors (red, yellow): left to right
cool colors (blue, purple): top to bottom
