Well it depends what you mean by 'neural'... Blood pressure is
controlled by various systems, for example local metabolite
concentrations in tissues and blood vessels, Starling mechanisms in
the heart itself and a more global regulatory mechanism from various
brain centres e.g. sympathetic/parasympathetic efferents to the heart
and neuroendocrine axes. However if you mean by 'neurally mediated'
whether blood pressure is to some extent unde conscious control then I
don't know. You can manipulate the mechanisms that control blood
pressure, e.g. if you hold your breath your heart rate falls, but as
to just thinking 'lower blood pressure' and it happening I doubt it!
Of course certain states of mind such as stress do affect BP, but
again via the 'unconscious' mechanisms.
