Q&@
A CONGERIES
OF BIOCHEMICAL REACTIONS
AND ELECTRICAL CURRENTS IN THE BRAIN
CREATES THE SUBJECTIVE EXPERIENCE OF PAIN, ANGER OR LOVE?
Perhaps we wìll have a solid explanation in 10 or 50 years! But as of 2016, we have no such explanation,
and we had better be clear about thàt... Using fMRI scans, implanted electrodes & other sophisticated gadgets,
scientists have certainly identified correlations and even causal links between electrical currents in the brain
and various subjective experiences! Just by looking at brain activity, scientists can know whether we are
awake, dreaming or in deep sleep. They can briefly flash an image in front of your eyes, just at the
threshold of conscious perception, and determine (without asking us) whether we have become
aware of the image or not?!! They have even managed to link individual brain neurons with
specific mental content, discovering for example a 'Bill Clinton' neuron & a 'Homer Simpson' neuron!?
When the 'Bill Clinton' neuron is on, the person I thinking of the 42 president of the United States of
North America; show the person an image of Homer Simpson, and the eponymous neuron is bound
to ignite?! More brooadly, scientists know that if an electric storm arises in a given brain area, you
probably feel angry! If this storm subsides & a different area lights up - you are experiencing love.
Indeed, scientists can even induce feelings of anger or love by electrically stimulating the right neurons!
But how on earth does the movement of electrons from one place to the other translate into a subjective
Image of Bill Clinton, or a subjective feeling of anger or love? The most common explanation points out that
the brain is a highly complex system, with more than 80 billions neurons connected into numerous intricate webs.
When billions of neurons send billions of electrical signals back & forth, subjective experiences emerge. Even
though the sending & receiving of each electric signal is a simple biochemical phenomenon, the interaction
among all of these signals creates something far more complex - the stream of consciousness.
We myDiadepts live & love stories even if we make them up ourselves
while going from here to there or
sitting still without
'anything to
do'.
