Something like the Hypothalamus, for instance, will not grow larger, because its function is to do with hormone production, and it is large enough already for sufficient amounts of hormones to be produced. Something like that lymbic system, which the hypothalamus is attached to, also, would not grow, because there is no emotional state that causes brain growth or shrinkage (and the lymbic system is to do with emotion). If one did grow larger than normal, and then shrink again, you'd see its effects - that being, one part of the brain would be squashed or degenerate due to lack of space and excess of pressure, and this would lead to it being underdeveloped (we see this in brain tumour patients - the cancer places pressure and stress on other parts of the brain, and they must either shrink, or the pressure causes the loss of bodily function or mental capacity, etc., etc.) - and after this, that area of the brain would not just "spring" back into its usual state of being. There are no foldaway parts of the brain; that's why when the brain swells, it causes brain damage, leading to things such as memory loss (severe in some cases, with the memory being limited to only a few seconds in relation to certain things not done through routine) because portions of the brain have been damaged.
