The photographs show faces as they are (centre), and with each side of their face ‘butterflied’ to give a completely symmetrical right side and left side view.

The 'logical' left side of the brain, as a generalisation, governs the right side of the body and the 'intuitive' right side of the brain the left side of the body.

• Do the differences we see in the sides of the face correspond to the differences in the functioning of the two sides of the brain?

• Are the more symmetrical faces those of people whose brain sides take equal responsibility for the running of the person?

• Does this change throughout our lives?

• Can we change the way our brain functions so that the left and right sides are equal and, if yes, will this make our faces more symmetrical?

This is the start of a thought process, I draw no conclusions and welcome your views. We're hoping to add a comments area soon, subscribe to be informed when this goes live and for other major updates.

Left brain functions

• Logical: Drawing conclusions based on logic; one thing following another in logical order.
• Verbal: Using words to name, describe and define.
• Analytic: Figuring things out step-by-step.
• Symbolic: Using a symbol to stand for something.
• Abstract: Taking out a small bit of information and using it to represent the whole.
• Temporal: Time aware, sequencing in order.
• Rational: Drawing conclusions based on reason and facts.
• Digital: Using numbers.
• Linear: Thinking with linked ideas, in an order, often leading to a conclusion.

Right brain functions

• Intuitive: Making leaps of insight, often based on hunches, feelings or visual images.
• Non-verbal: Using non-verbal understanding.
• Synthetic: Putting things together to form wholes.
• Actual, real: Relating to things as they are now.
• Analogic: Seeing likenesses among things; understanding symbolic relationships.
• Non-temporal: Without a sense of time.
• Non-rational: Not requiring reason or facts; able to suspend judgment.
• Spatial: Seeing how things go together as a whole and in relation to each other.
• Holistic (whole-istic): Seeing things all at once as a whole; perceiving the overall patterns and structures, often leading to differing and maybe contrasting conclusions.
