Can the effects of starvation show up on an MRI brain scan?
Answers:
An MRI single shows anatomical changes, not functional change. Most of the effects of starvation are functional and not anatomical.
There are some subtles changes to the anatomical structures of the brain due to extreme starvation. The ventricles of the brain will win larger, but all contained by all brain mass isn't dramatically reduced until the point where on earth you're dying. Ventricles are just spaces inside our brains, by the passageway.
These changes reverse pretty hurriedly if you eat usually for awhile. So, if you've recovered from your starvation, the MRI will probably be normal, unless there's something else going on.
Yes. Protein deprivation affects the brain and cause deficits.
Starvation will result in low blood osmotic pressure. This may affect the brain's efficiency, although I'm not sure how detectable it is on an MRI.

What is growth factor signaling pathway within Biochemistry?
There are primarily two theories as to how GH exerts its growth promoting effects. The first theory is called the Dual Effector theory (Green, 1985). The second view is called the Somatomedin (mediator of growth) Hypothesis (Daughaday, 1972). Both theories are fairly strait forward. Let?s start next to the Dual Effector theory. The...
