Neural
Influences
 It
is unlikely that only one structure of the
brain is solely responsible for aggression.
 Anderson
& Anderson (1998) found that
both humans and animals several
different parts of the brain have been
identified to be involved in the production
and control of aggressive behaviour.
 The
Hypothalamus and
the Amygdala are two
structures located
deep in the brain.
 These
are made up by
neurons, which can be
manipulated by
electrodes to control
normal functioning.
 Animals
such as dogs
and cats have been
observed to be
particularly
aggressive towards
animals that would
usually produce a
neutral response
when the amygdala
and the
hypothalamus are
activated by
electrode's
 Researchers
have
been led to believe
that the amygdala is
the structure of the
brain the contributes
mainly to aggression.
 The
cerebral cortex is
responsible for how
we interpret someone
else’s behaviour, for
example a
threatening gesture
can be interpreted as
either an aggressive
act or a joke.
Depending on who
makes it, when and
where.
Example 
A
normal peaceful woman who was
suffering from a brain related disorder,
had an electrode placed on her
amygdala by the neurosurgeon. When
the electrode activated the woman
became aggressive and snarled “take my
blood pressure. Take it now!” she then
tried to hit the surgeon.
