I am not starting a comparison between hands and brain. Nor am I trying to establish a relationship between the two. I leave it to the researchers and the people reading this to opine upon my observations and what I am trying to tell. I am a forensic scientist working for Police Department, specialist in Fingerprints,with over 32 years experience. I am still active and energetic.
The human brain is a paired organ. It is composed of two halves (also known as cerebral hemisphere) which are a bit of look-alike. Left and right half. Similarly human have two hands. Left hand and right hand.
The development of fingers and the brain lobes start between 12 to 15 week of foetus life. Dye to their simultaneous development and growth many researchers and scientist have tried to establish relationship between Fingerprints Patterns and Brain Lobes. Dr. Harold Cummins was such a doctor who gave very positive relationship between Fingerprints Patterns and Brain Lobes. He even coined the relationship as “DERMATOGLYPHICS”. According to Dr. Cummins, each Fingerprints Pattern is associated with some Innate qualities/ potentials, Personality Traits, Human Behaviour, Skills, Vocations, etc. Reading and analysing the fingerprint patterns on the hands of kids as little as 3-5 years of age, their innate qualities can be known such as whether that child will be Extra-ordinary in reading skills, or sports or vocational training or that child will prefer acting, dancing, singing, etc.
Paul Broca suggested a mirror correlation between cerebral hemisphere ( half and opposite) and the personality traits i.e. the human left hand movement is being controlled and supervised by the right cerebral hemisphere of the brain.
In 1999, neurologist Frank Wilson wrote a book on hands. Inspired by his own efforts to learn a challenging manual task – playing the piano – and working with people with injured hands, he compiled a book on the intimate relationship between brain development and how we use our hands.
Each cerebral hemisphere is having lobes or parts responsible for performing function, activity, etc related to that part. They are:-
motor strip location, impulsivity, short term memory, emotion, voluntary movement, social functioning, creativity, expressive language.
sensory strip location, perception, touch(pain & temperature), ability to draw, reading and writing, calculations.
hearing, long term memory, verbal and written recognition memory, receptive memory, music, initiation of verbal.
coordination, balance, ability to judge distance, muscle tone including the muscles required for speech.
Connects with the spinal cord, reticular activating system, thalmus, hypothalmus, heart rate and blood pressure, smell and taste, eye movement, appetite, vision, balance.
