T
his is generally how the 2
hemispheres of the human
brain are depicted. The
one on the left is that of
the right-hand dominant person
(shades of grey; compartmentalised;
predictable), and the one on the right
is of the left-hand dominant person
(twirls of colour; different fonts; full of
imagination). They go further to say
that those character traits mentioned,
can be aligned with that of a right or
left-hand dominant person. This is
just a generalisation, but there are
always some nodding heads as I show
this slide, in agreement with the fact
that lefty’s show signs of creativity,
musicality, imagination, etc.

In the brain we find something
called the Corpus Colossum. This
is where the 2 hemispheres of the
brain communicate with each other.
Their brains are more flexible-their
understanding of music could be on
the left, and maths could be on the
right. Research has shown that in
lefty’s this area is 11% larger than in
the righty’s. The main reason for this is
because the lefty is exposed to much
more right-handed challenges than
the righty is exposed to left handed
challenges on a daily basis. These are
things like bottle tops, buttons, zips,
reading and writing, to name but a
few. This advantage gives the lefty
more bilateral brain activity-according
to dr. Amar Klar-which can be an
advantage in visualization and problem
solving. So theoretically they use
both hemispheres to manage stimuli,
resulting in faster overall processing
and response time. The research also
showed that when one side of the
brain became overloaded and slowed
down, the other side could pick up
the slack without missing a beat. The
theory then also stands that lefty
seniors could retain mental quickness
for longer than the righty’s.
Growing up with everything
right-handed, lefty’s give their nondominant side more exercise than the
average righty. Bio mechanic research
has revealed that training the nondominant side actually enhances the
dominant side. This is known as the
cross training effect-since the body’s
neural network is integrated on both
sides.
Studies in the US, UK, and Australia
have revealed that processing of
language, special relations, and
emotions takes place in more diverse
and creative ways. It also showed that
lefty’s are more gifted in music and
maths.
Chris McManus says that historically
lefty’s have produced an above
average quota of high achievers.
He says it’s because their brains
are structured differently, with an
increased range of abilities.
In an article in the journal of
Neuropsychology 2006, it was
suggested that lefty’s are faster at
processing multiple stimuli, for e.g. a
jet fighter pilot; talking and driving at
the same t
