Psychosurgery is
treatment involving —
(a) the
use of a surgical technique or procedure or intracerebral electrodes to create
in a person’s brain a lesion intended (whether alone or in combination
with one or more other lesions created at the same or other times) to alter
permanently —
(i)
the person’s thoughts or emotions; or
(ii)
the person’s behaviour other than behaviour
secondary to a paroxysmal cerebral dysrhythmia;
or
(b) the
use of intracerebral electrodes to stimulate a person’s brain without
creating a lesion with the intention that the stimulation (whether alone or in
combination with other such stimulation at the same or other times) will
influence or alter temporarily —
(i)
the person’s thoughts or emotions; or
(ii)
the person’s behaviour other than behaviour
secondary to a paroxysmal cerebral dysrhythmia.
