Regional temperature rises within the
CNS can lead to an alteration of mem-
brane properties. For example, enzyme
activity – ornithine decarboxylase – is in-
creased when calcium flows into the cell
via a temperature-sensitive mechanism.
Interestingly, one study observed an acti-
vation of this enzyme after EMF exposure,
subsequently resulting in a temporary per-
meability increase of the BBB.
On the other hand, also a tempo-
rary blood pressure rise could cause an
increase of BBB permeability.
