I've always assumed that the "brain freeze" had something to do with
the relative location of the hypothalamus to the human palate and the
constriction/dilation of blood vessels around this area.
Actually, headaches can be subjectively localized to a number of
locations around the head (e.g., temples, occiptial region, etc.).
The headache doesn't occur in the head but on the surface of the skull
as stretch receptors react to the constriction/dialation of the vessel
walls.
Hope this helps some,
