the radiation kills bacteria, so no it would not decompose, only dry out and freeze, similar to mummies found in the Andes.

The temperature changes would turn the human body into jerky relatively quickly. The Incas used to mummify their dead kings by putting them on a mountains and letting the hot days and freezing nights dry out the body.

The sun would desiccate it and solar winds would eventually strip the body apart.

How preserved would her brain structure be after that?

The parts of the body in sunlight would get hot very quickly and the parts in shadow would get cold. That alone would probably do horrible stuff to a human corpse

considering the neurons and binding structures take irreversible damage when dried, it would be not more than a dry lump of fat.

If the body is in sunlight, it would cook and dry up until its hard leather. If its in a shadow or on the dark side, it would freeze.

No. It would dry out very quickly in vacuum and be sterilized, then slowly cool off the core temperature to ambient Moon surface temperature while the surface of the body is cratered by rare debris impacts, then even more slowly be turned to dust in the bombardment of solar radiation.
