Restrict access to area within a layout?

Hi, can anyone tell me that if a layout is setup and you break that layout into a few seperate quadrants and you want to give specific users access to control only a specific quadrant, can that be done? Restrict an area within a layout based on a users login?

You can give permissions to users at the region level yes, but to be able to edit the layout at all, they will need permissions to edit the layout. So you can prevent them from modifying some regions on a layout, but you can’t prevent them from adding or removing extra regions.
